86 200X suggestions

**80'427** · 03-02-2005, 03:20 PM

Sorry I didn't look hard enough to find those specs. Wow I paid 1500 for it either I got a bad deal or now it should be worth at least 2000 or so. Wiseco does offer a 12.1 and 10.5 piston so I could bore it a bit (to clean) and do the cam and head and that should get me a little more power. Will 10.5 run on pump gas? Anyone done any of these mods? Would the 26mm carb really help? Can I steal one off another stock rig? From looking at the other engines on the spec page this one is really one of the hotter engines. I guess I like it enough to try a few upgrades plus buying a totally different rig would be hard this year when we are already getting one new one. Since I am kinda ignorate what do you mean by a sister? Is that like a 250 with the same basic case? Kinda like a Small block chevy 305 350 share the same and similar parts. Thanks for your help so far, helping to strighten me out.

You americans always have the same answer for everything - buy a bigger one!.

Stick with what you have and work it. Everyone will envy a 200x that blows off 250r's and 350x's.

Do some port work for better flow, get an aftermarket cam, get a 34mm carb and big bore it as big as you can. The key is to make it breathe.

Regular pump fuel will run on upto 10.25:1 but if you want power go for something in the 11's and run premium.

I am not new to increasing preformance just on doing it on ATCs. I do plan on keeping it and doing what can to make it faster. Never know may figure out something cool.

**80'427** · 03-02-2005, 04:32 PM

would a 27mm carb off a 250x work? Another dumb nubee question is how do you know what size a carb is? just measure the inlet? You know a sneeky pete bottle would fit under the seat. Does pulling the airbox lid really help? Alway been afraid of filling the box full of mud/water.

**jenndnn3** · 03-02-2005, 04:45 PM

Haggle, I respect your knowledge you have a ton, (in fact I hope to pick your brain when I start my 85 next week) but I hate to disagree with you on this one instance. I do not see any performance for this particular engine, that will take it to the level of the 350x and 250r. You said key word Breathe, you have choice of stock pipe, slightly up from that to a cobra, to an upgrade of same or more depending on which of us Americans you talk to on the RCM. I havnt seen any proof any of these really do anything more then stock. I did not see any cam out there for it but if there is I said go for it. Cam being one of your biggest getters. I am not a fan of bigger pistons for performance, but hey have at it.

80'427 all you can do is try. A sister engine, what I mean is the 85 200x has the xr to pull from the 200s and so on and so on. The 86 changed so much, there has to be a sister out there. And if we find the sister then maybe we open the doors a little bit more for performance.

**Lomax** · 03-02-2005, 05:24 PM

jenndnn3= I have had the same problems that yall are running into finding performance parts for the 86 model X. As far as a Sister engine there are only 2 other Bikes out there, 86-88 200SX Fourtrax and Honda 200 Type 2 (I dont know what years that thing was around). If there is another machine out there even remotely close then I cant find it anywhere. On mine, I am just going to run the DG carb, DG pipe, Port and polish the head, slight bore, higher comp Piston, UNI filter and a Cam if i can find one. Ya'll might dig something up that I just have never found and good luck to you for that.

I had my head ported and polsihed, 10.25:1 piston anc kept the stock cam, I was told the aftermarket cams are all top end to different degree and I really like how the bike makes good bottom end, also I got a 27mm carb, I have yet to install it. I have a 250r(I gotta install my 310 pv), crf450r quad, restoring a 350x and doing a cam, port/polish, 10.25:1 piston, suppertrapp exhaust, suspension, the whole nine yards.
So, I'll leave the 200x to where it belongs, playing around in the tight woods, I'm not looking for crazy power from it, I know I won't get it. Still on my 200x, I'm pretty fast in the woods, the quad guys around me have a hard time keeping up with me. My advice: leave it for its intended purpose and get a hi horsepower trike if you want a powerhouse. I also have a 01 xr250r, It has a cam, port/polish, carb and a pipe,its not a powerhouse, but its good for its intended purpose, riding fire roads, again its hard to catch in the woods, and rding back and forth to the trails, work, etc. If I wanted a powerhouse(and a I had a husky tc610, wow that was powerfull), I will buy one. BOTTOM LINE: don't make a bike do something it was never intended to compete with, it just makes time bomb, because the tranny, cluth, rod, wasn't made to take the stress. Also remember, work on suspenion first, there is no use having a fast motor on a poor handling bike, sure it will go fast in a straight line, but you will get buryied in turns, whoops, rough stuff.

**jenndnn3** · 03-02-2005, 09:06 PM

So that brings my next question is there a cam out there? Wouldnt mind one of those myself.

Deathman makes excellent points all around. He is right on the suspension, but that is an easy fix there are very good solutions, but whats the point, if you cant beef this engine up. I have searched as well, and every door was shut. Some slammed. Trust me guys it was my ambition when I first got this trike to make it as fast as the bigboys. Wasnt gonna happen. Even with big money I was hopin to spend. I woke up. But hey I have an 85 200x as well now, and guess what. She wont be chump change.

Lomax you really think that is the only one? Those 3 are the same engines, 2 of em rarer then the 200x I was hopin they made something that was remotely close. But I long ago gave up looking.

They all use the same topend design, The X making the most from it out of the 3. The only benifit from it is that it makes finding top-end parts a little easier than having to kill another X to get them. It is sad that the aftermarket never made alot for them because they are superior machines to the ones that they replaced stock for stock.

Yes Web cams makes 3 different cams for it. This should take you there.

I was thinking the small one to keep that strong lowend.
I agree it is awsome trail rig, 99% of time that is where we ride. That is why I like it and don't really want a bigger one instead. I would like to get some more topend, but I am not asking for the world just the abilty to cruise with larger machines without struggling. The other thing is we are getting a bigger 4 wheeler for my wife so I will be able to get that big power if I feel the need. I am just trying to pervent what happened on my jetskis. We had a 760 first then got a 1200 (1 of anything is no fun). The 1200 can cruise easily at a higher speed and the 760 struggles to keep up. So I am just asking for a little up top to help out on the long straights. I am a horse power junky so later I may change my mind but for now this is how I feel. Cool enough?
Thanks alot guys.

I was at work for the last post and was thinking on the way home. When I posted in the begining I wanted to know more than just enigne struff. I would also like to hear things like if I am the only one running 20" tires and if that is slowing me down. If I sould gear up to put me back to where It was with the 22s. Where the sweet spot is on the stock rig, heck I may be over reving it and should gear it up to lower the rpms. Does the CDI box contol the revs or is it just what ever the rig can spin to under load and valve float?

**80'427** · 03-02-2005, 11:34 PM

Hey jenndnn3 I found you a cam, so what about that feet kissing?

**jenndnn3** · 03-03-2005, 09:45 AM

I am running 22's plain ugly knobbies with stock unsure or forgot what my sprockets are, Ill count em today. I know that 6th gear is somewhat wicked if you can open her up to that. I was actually surprised she had it in her at 6th gear. You can change alot by playing around with tires and sprockets. Do search they discuss what each will do, I would tell but I always get it backwards, when I type it

Closest I can come with enjoy.

**whiteman350x** · 03-03-2005, 09:58 AM

I have 2 86's. One is basically stock and the othes is modded pretty well. I went with a 12:1 pistion, the middle grind of the 3 webcams, I also got the spring kit. I am running a cobra pipe but still have the stock carb. I plan on upgrading the carb soon. With all those mods, I really woke that little motor up. The problem with it now is I have more motor than suspension. I do recomend replacing the cam tho. That was prolly the best mod I did.

**80'427** · 03-03-2005, 10:57 AM

I think I will just do a head clean up and a cam swap. Don't really know which cam to get but suspect that to keep my strong bottom but add some power all around I should go with the small cam. I will leave the compression alone until it needs a rebuild. May add the bigger intake valve to help in high rpm flow. My only concern is shrouding the valve, never seen a 200X combusion chamber.
