Rebuilding 200x After 6yrs

[rodeofan5656]

So i warn you now, i have alot of 200x questions.

This will be kind of a "duplicate" thread, as i didnt seem to have access to the Trikesylvania section until after the first thread in the New Members section...... http://www.3wheelerworld.com/showthr...-ATX200X-Build

1986 ATC200X- Ive been away for awhile. But I finally got the engine out and the top end apart. Found alotta slop in the piston with wear marks on the piston skirting and cylinder walls. Which explains the excessive oil burning and exhaust smoke. Ive got a few questions about this build, with hopes that someone can help me out.

1) i plan to go with a Wiseco piston, 10.25:1. Ive been told the 12:1 is known for destroying transmissions (?). JSR Performance of Wichita, KS can do the bore job for $45. Fair?

2) the camshaft, chain, and guides look alright, except for a shallow groove worn into the front side (non-tensioner) guide. Is the guide still ok to use? What should be replaced? Also, the rockers has some visible wear, on camshaft ends, you can feel with your fingertips. Should these be replaced? And where to buy?

3) bent rear axle and rigged axle bearing carrier I read awhile back about a 300ex swingarm swap, but cant find anything anymore. Can someone point me in the right direction? Or have any access to an axle and/or carrier?

4) cosmetics- i have a cut up atc110 front fender right now, and it looks terrible. No rear plastics. I also heard 300ex rear plastics will work with slight modification. Where can i find this info? And also, something about an old 250r front fender fits the 200x?

Thanks for any info you have! Glad to be back.

UPDATE: The shop has the cylinder now. They are boring the cylinder, ordering me a Wiseco 65.5mm 10.25:1 piston kit, and full engine gasket and seal kits all for $220 before tax. I highly recommend JSR Performance of Wichita, KS to anyone needing parts and service!

They will have my rockers hard welded later, and are full of information!

In the pictures, you can see the inside of the engine casing is cleaner than the outside! Also, you can kinda see the wear of the cam and rockers.

Another question- on the stator coils, 2 look to be coated. Is this normal?

Hello, well it sounds like your heading in the right direction. You can probably get away w/not replacing the cam chain guides if there not to worn or dry rotted (lots of small cracks) but i'd definetly do the chain. Its a 100 link 25h-chain http://ebay.to/2hkPLUq its pretty cheap insurance.
Make sure to grab a engine seal kit too while your at it, the upper decomp seal is discontinued and doesn't come with
The kit you can buy on ebay. I bought a bag of thirty of them (just decomp seal) if u end up going that route let me know.
No charge.
Make sure your machinist orders 86/87 piston not 83/85 theres a difference im just not sure what?(anyone)?
The cam and rockers well you'll figure that out $$$. Search 86/88 trx200-- and fatcat you may come across a nice used set.
There's definetly more knowledgeable people here then me but i figured i'd put my 2-cents in...
Yes its normal--
Shep
Jeez- grab some new valves too..(ha)

Idk if its the 200x, but i saw a build about a 1982 200cc and the piston crown was dished. Mine is more of a dome. But i specified pretty hard on the year, and watched him find the part number in the Wiseco catalog. If its incorrect, its all on him.

Thanks for the stator picture, that makes me feel alittle better. At first i thought they were burnt

Here is a website for Honda.

So i tore into the head today. Valves could be reused, but guides are SHOT. So ill probably do new guides and valves. Can we still get guides for these things?

Found what looks like grind marks from where someone tried to taper the intake port (?).

Also found some good info about the 300ex carrier and axle conversion.

Trying to get the forks out of the trees to have the lower tubes polished. Also gettin frame ready for paint. Not sure on a color yet But i dont think this will be a restoration. I think itll be a custom/rider. So itll be all personal. I like all black, but i want just alittle flashy. Cant quite find a color scheme i like

[Shep1970]

I'm pretty sure all the intake ports were chamfered like that at honda
To give you ideas here's my sons a few years ago

Logan, I believe you may have forgotten this posting from a few years ago (?),,,, sounds like the TRX fenders are a fit with some mounting hole re-location.

When/if you get to the fender part of your rebuild and need some detailed pictures of my 2004 ( or 2006 ~ can't remember what year it is right now) TRX300EX fenders that I made into a trike by putting 83/84 250R front end on it,,, give me a shout.

[rodeofan5656]

Well crap, i completely forgot about that one. Its been so long, i googled the axle carrier and took me to an old thread i had posted years ago. I'll go back thru that one and see what i can figure out. But with the price of plastics these days, i might as well do the direct fit Maiers. I do like the round look of the EX fenders though

[rodeofan5656]

I hate to start a new thread for each question, cause they keep piling up the further i get into this thing. Like that fact i need valve guides and these are all i found. Hopefully someone who has used them will take a gander at the thread and give me some input

[Dirtcrasher]

Yes, Kibblewhite is good.

[rodeofan5656]

Thanks for the OK. I was startin to get worried. Got one of our Recon guys at work to do a polish job on the lower fork tubes. Itll cost quite a bit more than paint, but itll sure look better. So it may not be runnin quite yet, but itll look purdy!

Id love to post all the pictures ive been taking. But uploading them as an attachment 1 at a time, gets old quick. Anyone know an easier way to add multiple pictures to a post?

Photobucket

[rodeofan5656]

I tried photobucket on my phone and it went crazy. Started opening tabs like pop ups, and wouldnt let me login without adding my Facebook info. I just didn't feel comfortable with it.

[rodeofan5656]

Are all the steering bearings the same on all years of the 200x?

Ive got the engine about 40-50% apart. From what i can see, all the gears and transmission parts are good. Is it recommended to tear the entine engine assembly apart and separate the case? Everything rotates smoothly. If no one thinks theres much reason to go any further, i may leave it. The only things i have left to remove are clutch assembly, and parts to access cam chain and guide.
