stroberts22 86 atc 200x

[stroberts22]

I have a old 200x that I got when I was 12 years old for christmas. It's been sitting in the barn for over 18 years. I got it out the other day and cleaned it up and decided to go through it to get it running. I bought a nos cobra exhaust awhile ago waiting for the build. I ordered a 30mm mikuni carb and was wondering on oher mods I could do to it. I want to do a 12:1 wiseco piston, port job, valve job, new valve springs, retainers, mid to top grind web cam, and open up the intake to fit the 30mm carb. I already opened up the motor and found that every thing looked like brand new inside. I also got alot of the frame stuff ready to go to the powder coater. I need sugestions on the motor because I never messed with a 200x motor at all. I got alot of fond memories on this machine and can't wait to get it running better than new.

[Dirtcrasher]

Your fine, it's an easy motor to work on.... Such easy valves to adjust, so many upgrades. I love the 86/87X.

12:1, you haven't had it out for years, are you prepared to run fresh race gas consistently? It's hard to keep up with.

IDT if it's worth the trouble, I have done it......Wish I didn't. Too many trikes to keep fresh.

Get a nice 10.25 or 10.50:1 piston, a nice cam, the exhaust and carb mods and take the lid off the air box.

Just my opinion.

[stroberts22]

Will the middle cam web cam offers work with the 10.25 compression. All my trikes and 4 wheelers get a diet of 110 octane race gas only.

[Afrothunderkat]

110 in all machines?

hah, not good unless all your stuff is high comp. must not be ridden much.

[atc007]

While you and DC are both on the right trail. there's a Good chance Mickey Dunlap will see this now : ) He MIGHT know of a couple things to coax a little more out of her. Right at the very end,,Powroll/He,,had those things figured out quite nicely. Normally here,I'm saying leave it stock,enjoy it the way it is. But if you're already feeding Race gas to your stable,,lets see what this thing can do!!! I am a big fan of port,head work. I think I read somewhere they don't do a lot of porting to these? I know 350x and old style 200x,,but I have not stretched one of these all the way out ,,,,yet. I'd be willing to try : )

[stroberts22]

110 in all machines?

hah, not good unless all your stuff is high comp. must not be ridden much.
I go through 5 gallons every 2 weeks. They all seem to like it.

[stroberts22]

I mock the 30mm carb on the intake today and it fits good just needs the intake enlarged a little and it will flow good. The air box hose had to be heated and stretched a little also. http://i811.photobucket.com/albums/zz40/stroberts22/IMG_1505.jpg

[stroberts22]

Got some stuff ready to go to powder coated.http://i811.photobucket.com/albums/zz40/stroberts22/IMG_1506.jpg

[stroberts22]

Parts are already back from powder coating. Got a web cam and springs ordered and getting the magic done to the head to get her to run. I went with the middle grind cam. http://i811.photobucket.com/albums/zz40/stroberts22/IMG_1536.jpg

[threewheelin-feelin]

parts are looking good!

[stroberts22]

Got all the engine parts cleaned up and ready to start putting the engine back together.http://i811.photobucket.com/albums/zz40/stroberts22/IMG_1555.jpghttp://i811.photobucket.com/albums/zz40/stroberts22/IMG_1558.jpghttp://i811.photobucket.com/albums/zz40/stroberts22/IMG_1557.jpghttp://i811.photobucket.com/albums/zz40/stroberts22/IMG_1556.jpg

[gomer202]

looking good

[Dirtcrasher]

Who's porting your head? Any over sized valves??

[Husky250]

What is the carb off of? I put a 24 on my TTR (stock so I think) and it did wonders. I may like a larger one on the "X"!

[stroberts22]

The legend Mickey Dunlap is doing the port work and valve job. I think he just used stock size valves. The carb is advertised as a 30mm but I think they measure it different because it is bigger than stock but not by much. Mickey flowed the carb and said it didn't flow as good as the old school powroll carbs but will work alright for me.

[stroberts22]

I've been trying to work on my tank. It has heavy rust in it. I got a gallon of metal rescue and put it in last week and I got back from work last night and checked it. You can see the line that the metal rescue was filled up to in the tank. I turned the tank and started working on the other half. The part where the metal recue covered looks like brand new. This stuff works.

[jsmay]

any other updates? the motor looks mint...what did you paint it with? can't wait to see it done.

[stroberts22]

The porting on the head is done and waiting on it to get back. The cylinder is getting bored for the piston. I'm going to get the bolts and axle sent off to get them cadium plated. The tank needs to be painted but the inside is clean.

[oscarmayer]

looks good man!

[stroberts22]

Head is back for getting ported. I dropped the tank and other parts at the powder coaters. I never had a tank that I could powder coat because they had dents in them and had bondo in them. I hope it turns out good. Cylinder is bored for the piston. I almost ready to put the motor back together. Do I need to replace the timing chain and guides? The old one is a did chain and shows no wear. What other parts I need to replace in the motor?

[Dirtcrasher]

The 86 seems to be never as loud as the 83-85 200X timing chain and guides............. Not sure why, just design I suppose.

[stroberts22]

So, if it's not broke don't fix it or go ahead and replace everything while I'm in there?

[atc007]

If your chain is a recently replaced DID,and was tight. It's fine. If the cam and rockers look good,leave them to. Are you staying with a stock cam? You'll love this little sucker when she's all buttoned up!

[JJMF1979]

any other updates? the motor looks mint...what did you paint it with? can't wait to see it done.

Ya I would like to know the answer to this too have to do my engine in a week or so

[250esbigredNY]

Any update lately with all put altogether? im sure it gonna looks sweet when it s all done.

[stroberts22]

Any update lately with all put altogether? im sure it gonna looks sweet when it s all done.Yea, I posted some and they got deleted.

[atc007]

We're waiting ! Your stuff is awesome !

[stroberts22]

Tammy from Cosmic Quads sent me pictures sent me pictures of the completed seat she done for me. She did a great job! I can't wait to get it on the bike.http://i100.photobucket.com/albums/m40/cosmicquads/seat%20restos/Shannon1.jpghttp://i100.photobucket.com/albums/m40/cosmicquads/seat%20restos/Shannon2.jpg

[oscarmayer]

nice!!! can holder! :)

[Husky250]

I've written cosmic a couple times about getting a taller saddle for my X but never got a reply so you got me really jealous with that seat!

[atc007]

Dam that is pirty.

[Husky250]

You know, I don't mean to hijack the thread but I gotta say somthing. It occured to me that when I wrote that I never received any reply from Cosmicquads it may have appeared that i was upset with them or throwing a dig at them. This was not my intention. My intension was to say his seat is SWEET and I soooo want one, that's all. I know they are busy over there (just look at their website as proof) and my emails probably got shuffled around and lost...... trailprotrailprotrailprotrailpro happens and I'm not the be all end all of customers. As a matter of fact Tammy PM'd me today and asked if she could help me. Good on her. It wasn't necessary but she did. OKOKOK We now return you to your regularly scheduled thread.

[stroberts22]

I was putting together the bottom end today and the gasket set I got for it doesn't fit. The center case gasket doesn't go around were the kick starter is. I guess it's for a trx without a kickstarter. Has anyone else had this problem?

[oscarmayer]

they sent you a 200s gasket kit i bet. I had the same issue with my 200x when i redid the engine. I bet you don't have the side kicker gasket either. If the kicker gasket is there, then it was a goof up from the factory.

[stroberts22]

I got the seat in the other day from Cosmic Quads and it has inspired me to get the rest of it done. I got the motor together and installed but I still like some seals on the right cover, the seal kit I got didn't have the ones I needed. I tried to reuse a old trottle cable I had but it is to long and I ordered a new clutch and throttle cable for a 200x. The set of tires for the 84 250r is is backordered and they are waiting on them to ship all the tires together. I ordered ITP GNCC Holeshots for the 200X. Still like alot of little pieces most of them are ordered and waiting on them to show up. This thing is screaming for some oem fenders but maiers are going to have to do. This build has been easy. I was afraid that I ragged it out to much when I was younger but it is in good condition considering the abuse it has gone through. http://i811.photobucket.com/albums/zz40/stroberts22/IMG_1625.jpghttp://i811.photobucket.com/albums/zz40/stroberts22/IMG_1623.jpghttp://i811.photobucket.com/albums/zz40/stroberts22/IMG_1624.jpghttp://i811.photobucket.com/albums/zz40/stroberts22/IMG_1626.jpg

[pantera1975]

Wow that really looking goo. 86 200x IMO about the best looking color match up. It will look nice with LP tires on it

[atc007]

Wow man,,looking stellar. Beautiful work as always!

[jays375]

Looks Great!Don't worry about the Maier fenders.It will look good with the decals installed.Plus if you are going to ride it originals are just to costly to ruin.Only suggestion with the Maier is make a support to hold them out from the exhaust.Mine started to sag after awhile.143330

[Dirtcrasher]

You can make the OEM support work, but have to drill the fenders. If and when I do this, I just use SS hardware; Thats about the best I can do.

I'd never feel bad about using MAIER; OEM even used is usually priced outrageously and I'd rather spend the money on the motor or some other part of the rebuild......

I usually don't even run stickers because I ruin them with the pressure washer :lol:

Coming together nicely :beer

[tpit8787]

I had the same problem with the aftermarket seal kit,even though it says it works for the 86/87 200x I think it is probably only for the trx200sx witch does not have the kickstarter or the comp. release lever on the rightside cover.hammer hammer

[stroberts22]

I cranked it today on the 2nd kick! The carb is perfect for it. It runs great. After it warmed up it cranked on the 1st kick. I'm excited to get it back going.

[Yamaha_Rules69]

You did a really good job on that X! It looks flawless from the pics above. Good work!

[stroberts22]

I've got 3 builds going on at the same time so I guess I'm getting alot of practice. This one has went together without a hitch. The 200x is easy to work on and parts aren't to bad expensive either.

[stroberts22]

Hooked up the Cobra exhaust this afternoon and I don't see why these exhaust have a bad wrap. It sounds like a 450! I can't wait to ride it. You can stab the throttle wide open without any hesitation. Mickey done a great port job on it and everything seems to be working well together. I appreciate his help with the motor. I know it's not going to be a 250r but I thinking it's going to be pretty strong.

[stroberts22]

Still waiting on backordered parts but today I got tired of seeing it just sitting on the floor so I put some old tires on it and some 110 and run it around the yard with no brakes. It runs great. I can't wait to get it completely done.

[stroberts22]

I got the tires that's going to stay on it mounted up. http://i811.photobucket.com/albums/zz40/stroberts22/IMG_1696.jpg

[yaegerb]

Looks great!

[Toledo_Tommy]

Wow man . . . . . That's a very nice build !!! Nice work !

[oscarmayer]

sweet! now for some fenders!!!!

[stroberts22]

Yea, I also need to rebuild the front and back brake calipers to get some brakes and get my shock back from the rebuilder to be completely done with it. The carb seems a little rich. I'm going to have to get the jetting dialed.

[jays375]

That looks awesome!

[yaegerb]

hows the "bad boy" mugen coming along? I would love to see some video of it running when its finished!

[atc007]

A real beauty!!!

[dirtwheels]

Its looking great! I like all everything you have done so far. Got one of my 86's apart right now too. New thread coming soon when it starts going back together.

[stroberts22]

Still trying to get the clutch figure out on the mugen. I've been working on this in the spare time. I threw some jets at it today and got rid of the choke like Mickey suggested and the thing is running even better. It's going to be great on the trails because it's gearing in 1st gear. I went up on the counter sprocket to a 14 but it still creeps slow in 1st.

[250esbigredNY]

Wow, it looks great & what a sweet build you done with it so far. I am getting a 200x by this wkd hopefully..

[110klt]

what size and make of rears are you running?

[stroberts22]

The rear tires are ITP GNCC Holeshots 20x10x9 with Douglas blue label wheels to keep it light.

[GO OVRIT]

Thats a great looking 86. I'd love to see some video and hear how it sounds. What main and pilot jet did you settle on?

[stroberts22]

Thats a great looking 86. I'd love to see some video and hear how it sounds. What main and pilot jet did you settle on?
It's got a mikuni 30mm pit bike carb on it. It had a 100 main and I went up to 110 and the pilot was a 20 and I went up to a 25 and the needle is in the richest position. Seems like it is pretty close to perfect the way it runs. It is real rideable without any hesitation. I rode it all day today. I already got it broke in and not even done with it. I've fell in love with the 200x all over again. It's like going back in time everytime I ride it. Lots of good memories.

[stroberts22]

Here's a walk around and a start up of the 200x. This is why hillbillies shouldn't have a camera. lol. I think ya'll get a kick out of it anyway.
http://www.youtube.com/watch?v=gu8EC96kr2U

[jays375]

Sounds great!You should be proud how it turned out.Wish mine would start and idle like that cold.The second gen 200x is a great little performer.Everybody that rides mine are impressed.

[yaegerb]

Very nice sir. I am most impressed by your tuning ability. That thing runs like a sewing machine!

[oscarmayer]

good job man! :) you did a really nice job on it and just enjoy it.

[atc007]

LOVE your work friend!

[badass350x]

Very nice!

[stroberts22]

Thanks guys. I can't get over how it runs either. It's always started like that ever since new. Never had to choke it. I figured that I change the carb and it would be different but It's as good as new with alot more power.

[stroberts22]

Motor is broke in now and I did a gps run on it to see how fast it will go today. It went 60.3 mph which I was impressed it went that fast.http://i811.photobucket.com/albums/zz40/stroberts22/IMG_1719.jpg

[jays375]

They are little screamers!So how is the throttle response?

[stroberts22]

It revs quick with no stumble after it warms up. I think I'm going to keep going up on the main when I get back to the honda shop to get more jets.

[yaegerb]

gee, that is an impressive number. Can you do a high level recap of the mods you have done to it?

[jon jon]

im so jelious.. that is one of the nicest 200x's ive ever seen. great job

[tx200m]

Yes, that is nice..hope to make mine look that good soon. I only got mine to top out at 49 mph. :(

[Dirtcrasher]

^ could just be a different sprocket set up............

[tx200m]

True, true. Mine is box stock..and Im 240:lol:

[stroberts22]

I weigh 180lb and I went up 1 tooth on the front to a 14 to compensate for the 20" tires instead of 22". The rear is stock 38 tooth. The mods on it are port and valve job by Mickey Dunlap at 4 Stroke Tech. He also port matched my intake for the bigger mikuni carb. 12 to 1 piston was installed during a complete rebuild right down to spliting the cases. A Barnett clutch was installed. The carb is a 30mm mikuni that is found on many pit bikes. I rejetted it for the 200x and works real well. The air box inlet had to be heated with a hair dryer and stretched for the big carb to fit but other than that it bolted up to the stock intake. It has a K&N air filter and a cobra exhaust. The rear shock was rebuilt by Shock Therapy and all the adjustments still work on it. I rebuilt the front forks. All the master cylinders have already been rebuilt but still liking the calipers rebuilt. It has alot of factory oem parts that I replaced that are still available. I was surprised on how cheap it was to build this 200x unlike a 250r. All the parts are easy to find and economical priced.

[yaegerb]

nice. Engine-wise, the only differences between my first gen and your second gen build is that I will be using a 28MM mikuni roundslide and I lightened my flywheel. My sprocket set up will be different as well. I am using 18 inch rear Hoosier (small crossblock) so I will be using 13/34 gearing.

Thank you for the summary!

[stroberts22]

I finally got the fenders on but still like the brakes. I might be able to take it to trikefest if I get the brakes working.http://i811.photobucket.com/albums/zz40/stroberts22/IMG_1795.jpg

[jays375]

Looks good!Maier fenders have come a long ways.I have no issues using them.My trikes see a lot of time in the woods.

[atcpunk107]

That is the most beautiful machine I've ever seen. It gives me hope for mine. I also have an 86 I just started working on. Unfortunately the parts for mine are nearly impossile to find. But I'm not giving up. If I can make look half as good as yours I would be ecstatic.

[stroberts22]

Thanks for the comments. This one is special to me because I've had it so long. I got done with it completely today and got some video of it in action. I was just riding around the yard. I'm definately taken this one to trikefest.
http://www.youtube.com/watch?v=pvsZnBS3d9o&feature=youtu.be

[yaegerb]

Great job! That bike really rips. Excellent work sir!

[hadden]

Sweet! looks great and sounds great! I love the sound of someone ripping through the woods.

[jays375]

Seems to run pretty good!The second gen 200x are a blast to ride.Every time I think about selling mine my mind changes after riding it.

[jon jon]

boner acheived lol jk

[stroberts22]

I put the 200x to the test this weekend at trikefest. I took a basically stock setup trike to the motocross track and it kicked butt. It came in 1st place in mx. The drag racing was a different story. I went up against a poweroll 6mil stroker in the semi final and came up a little short. He easily won in the final. I didn't get a chance to race the loser of the final round to settle 2nd place so I was 3rd. I think I could of beat him. It ran really strong all weekend and was good on the trails. I hit double jumps on the mx course with no problem. I'm really proud of how it done.

[yaegerb]

Glad it performed well and great to hear you got 1st place! Makes me proud to own an X. Quick question Shannon. Can you tell me how much Mickey charged to match your intake manifold to your intake port on the head? I am curious because I may just break down and get that done rather than performing my "other" idea.

[sinsayers]

Beautiful X man, great work.

I finally got the fenders on but still like the brakes. I might be able to take it to trikefest if I get the brakes working.http://i811.photobucket.com/albums/zz40/stroberts22/IMG_1795.jpg

[Keepah Rolln]

very nice trike!!

[stroberts22]

I found this picture that rachel took of the 200x. Thanks for a great picture.http://i767.photobucket.com/albums/xx312/AnnelidM/TrikeFest%202012/2012%20MX%20Photos/DSC07187.jpg
