Boring out my 85 110

[85_ATC_110]

you can always do what the rednecks do, and weld a 350 sbc on the frame!

And then weld on some wheelie bars?? lol

I would mainly bore it out, not for a huge power gain, but to indeed clean the engine up like another user here stated. A new piston in a freshly bored out shaft just seems like a good idea.

How much of a modification would I have to do to put in a performance piston? Is it as easy as bolting it in, or are there modifications that have to be done.

What I have in mind so far is a bore (mainly to clean it), a performance piston, and new fuel lines, petcock and clutch. Any other ideas?

If I replace the clutch, should I redo the gears? Is it a good idea to replace anything while down in there (besides the seals)? Good idea to change to timing chain and such? I sure wish there was a complete write up on this already.

You could also put a 200x carb on it. Then get a nice K&N filter for the x carb. That would help out some with power.

a performance pistion is bolt in. It just has a larger dome to compress the Air/fuel in the cyclinder more

Will a 200x carb fit on with no problem? Or is there going to be some cutting and fitting?

Found a piston on eBay. Says it is a new .25 mm over piston kit for the Honda ATC and CT 110 models and it's going for $34.95 or about 36 bucks for "buy it now."

Is this a good idea for my atc, or is this not a performance piston. It's an "over" piston, whatever that means. And it says it is a bit bigger than stock, which makes boring out the old cylinder more possible. (replacement kit include piston, rings, pin and wrist pin clips) I am guessing it is not a performance upgrade?

no its not...its just the next size overbore

doing a big bore i was talking about means you need to get a bigger sleeve for your cylinder
