ATC110 Smoking

[mason.mank]

Hello, My 1982 ATC110 is smoking pretty bad with white smoke. It smokes while you are not throttling it at all, then when you throttle the smoke stops, but when you stop it starts again. Im not sure what to do with it, I read that if you have the top end sent it they can reuild it and it will stop smoking. If any of you guys know what to do, i would appreciate the help. Thanks.

Hmmm. Oil is typically blue smoke, which rebuilding the top end probably won't fix. It sounds like you are burning (boiling, actually) water somewhere in the system and its coming out your exhaust. You take it through any water lately? It been sitting outside?

[mason.mank]

Nope, its been in my garage. Just changed gas, oil, spark plug. I bought it from a guy who said he had kept it in his shop. Thanks

id take it for a good long drive white smoke is ok its just moisture in the muffler. blue is bad.

To address your rebuild question, I think there is a
valve seal on the exhaust valve that can cause excessive oil
consumption and blue smoke and might save you a rebuild.

White smoke is a different story. Does it smell like anything in particular?

[Mr_RPM]

just because its white does not mean its not oil. I agree, get it real hot and boil off any moisture it has, but chances are its time for a rebuild anyway, these old trikes are all long over due by now.

your going to want to bore it to the next size up to get a fresh cylinder surface and a new piston with rings to the new size of the cylinder.
(well you generally match the cylinder to the new bigger piston you get but you know what im saying)

Thanks everybody. I am new and don't know much about these things, and I really appreciate all your advice. Are you talking about sending it in and having the people over bore it? Because i have no clue how to do anything like that. Thanks!
Mason

[Mr_RPM]

yes, your local Honda ATV dealer or machine shop could do it.

[mason.mank]

Alright, thanks a lot for the information.

About the boring... I could not find a shop in my area that was even remotely interested in boring a jug. And that includes the honda dealer. I ended up doing it myself with a hone. It's trickey work so if your not confident then don't do it. Good luck finding a shop to hone it for you. Should be easier for you in wichita than it was for me in the middle of nowhere.

[Mr_RPM]

thats weird, i have 3 local shops 30 mins drive either one who would do it.

Are you saying that you needed a bore and used a hone instead?

[Midnite_rider]

He is in canada..... That may be the difference.

I was thinking the same thing. He says it is tricky work - I believe that. That would be some trick boring a cylinder with a hone.

[mason.mank]

Yeah... don't think ill be doing that. Ill try to find a shop around me to do it. I let it run for 30 minutes, it is still smoking but not as bad. Thanks for all the information.

Smart ass me read "ATC110 Smoking" And the first thing I thought was "You'd better take away it's lighter." Silly buns :D

[mason.mank]

I started it again today and it started smoking even worse, anyone have any ideas. I don't know why it would be better than get even worse. It hasn't been outside at all, it has been in my garage. I have no idea what is wrong, thanks for any help.

Do you have thin oil in it? 5w/30 or something? Try runnning thicker oil in it... SAE30

[pcollins]

If you didn't actually have the cylinder bored, with some fresh crosshatching and new rings and piston, Its no surprise its still smoking. Just plain old new rings aren't really going to help anything at all. Theyre still riding on that same old worn out cylinder surface, even if you ran a honing stone into it. The cylinder needs to be replaced, or re bored, with a matching piston and ring set. Valve seals wouldn't hurt either.

[mason.mank]

Right now i have 10w40 in it, is there something better to run in it?

[Thorpe]

Try runnning thicker oil in it... SAE30............

[mason.mank]

oh, sorry i didn't see it. Ill go get some later tonight and try it out, and see if that helps.

mason about the boring you were asking trailprotrailpro the guys got off subject...did you find someone to rebuild the motor yet?
what you are looking for is a machine shop. google or use yellowpages to find a machine shop. HONDA will charge a ton, im guessing they will also want to put honda factory parts in it and charge a ton..you can buy aftermarket parts like wiseco piston and rings. usually there are small machine shops around town and guys that do it at their house. they usually do all types of engines or motorcycles. best bet is to load up the whole bike or remove the whole motor and take it to the shop to show them what you want. machine shops can usually order parts for you and put them in or just sell them to you and let you put them in. they will know what size piston you need.
if you bought the bike for cheap, only a couple hundred, dont be suprised to have to spend that same amount on a bore, piston, rings, labor, etc...
if you are really interested in learning about the motor, you should get a shop manual for that bike for about $35 and read it. it helps you disassemble, clean & reassemble the whole bike piece by piece with photos to help.

[mason.mank]

I haven't looked into it yet really, i talked to the guys at the honda dealership who have a HUGE service department. They said that they would definitely do it, the guy i talked to even said to try to find a smaller business to do it because they would charge less. Ill look into having it done soon, thanks for all of the information.

I actually used a three stone hone with coarse stones. It doesn't take all that long but its trickey because you have to constantly stop and thoroughly check your work so you don't end up out of square. I just did a .10 overbore and got within .001 throughout, so it is doable. And yeah Grande Prairie AB sucks for service. Everyone just wanted to sell me a new quad, not happening. Funny enough my 110 does exactly what you describe, even with fresh rings, valves, and cylinder. Doesn't seem to have any noticeable ill effects tho.
