1986 Honda ATC 200x

[Budget_Blaster]

I know its not a blaster but...My little brother called me and said a friend of his got a 1986 honda atc 200x running for 50 bucks but after riding a couple hrs it just quit running and has no compresseion.Wanted to know if id be interested in redoing the motor for the guy.So i went to look at it and its in damn nice condition i thought about just buying it off him since my first atv was a 3 wheeler.

Anyways i pop valve cover off to see if the valves are moving and the chain broke a master link so i immediately stopped and told the guy id need to do some home work since i didnt know if it was an interference motor or not.Are they?

They guy wanted me to just put the chain back in and put in a new master link and i advised against it but hes trying to be super cheap and i think if i did that it would be a ticking time bomb.im not too keen on a stretched timing chain and 26 y/o timing componets so when it blowes i get blamed for half assing it.

What are your opinions of these engines?Easy to work on?Durable?Expensive?

Would it be worth the trouble and money after it snapping the timing chain for me to get it and build it.Its in unbeliveably nice condition and the plastics arent even broke has a uni filter and a funky ass looking DG exhaust setup on it.

sometimes when the timing breaks, it isent good for the motor, and it probs took a couple years off the life and for being 26 years old,....

I would take the top off and inspect everything. But I would definently fix it up. The 200s didn't have the best motors to start with, but its still worth it. Or find a pull rope atc 200 motor and put that in there. I've seen lots of people do that. Be slower but more reliable.

my 87 200x had a severly stretched timing chain, slapping away inside there for over a season, till i got the nads to tackle changing it, the guides were almost worn thru also, so they got new too,
ran like a champ till i sold it 2 years later to purchase my fist new blaster in '96

prolly doesnt answer your "interference" question directly,
but the timing from my stretched chain had to be off bad, as power was way down,
so i'd "guess" that no, the valves will not hit with a snapped chain.
a bore scope down the plug hole to inspect for piston damage may work, but removing the head would allow you a valve job too.

definately worth fixing if it's in good condition, very fun bikes !!!

Right site, but I wanted LMGTFY Epic fail on my part for humor Bigest problem would be if there are missing pieces of the chain. Would have to think if you can kick it over probably no damage to head. Look through that to find process to replace chain. He might not want to pay fair price to do job, or you might not want to tackle it either. Or might get it cheap now and do it on your own dime.

I would just do a full rebuild on it. If it's in real good shape, it may be worth it.

rebuild the thing! I would buy it off him cheap and keep it for yourself. If he can't fix it, that's his problem.

I've helped people out and done cheap fixes that they wanted despite me telling them that it was not a good idea....then they go and blow up the motor. It sucks to put time and effort into something just to have it fail right away!! Unless you're helping the guy so he can come riding with you, I would tell him to find someone else to half ass it.

That's so true. It's the owner that's to cheap to have you fix it the right way but you get the bad rep when it breaks again.
