ATC 110 build

[1979atc]

I have a 1985 ATC 125M and frame with my 1984 Atc 110 forks and plastic. I am putting my 1979 Atc 110 motor with my H&S cylinder on the frame. It would be better with an aftermarket frame, but I don't have the money to spend on one of those right now, maybe one of these days. I plan on making a Dickson joker or Sprint frame at school in welding class one of these days. I'm not a big fan of the chain tensioners, I have a BAPP chain tensioner but I have it on another bike right now. These aftermarket parts are also going on this build, BAPP breather dipstick, sudco intake manifold, oversized carb.
I have also been working on these cases for another bike I have, with a 123cc piston kit.
Sorry about the side ways pictures I can't get them to rotate.

[Joseph Farrow]

Cases look good. I know that was a lot of work.
I have found that if you use pic's from your phone you have to rotate them on the phone before you down load them onto the site.

[1979atc]

Yes thank you I'll keep that in mind, and the cases have a lot more to go a lot of wet sanding and polishing.

I've been running xr 100 carb, on my sudco intake on my stock 90 with pipe and stuff, On this build im going to get a aftermarket xr 100 carb or another stock one. And I commented on your video, im Allen Bingle on youtube. After its done I will put videos on my channel of it.

Dr. ATV has a lot of parts for the 110-125. The 85 ATC110 is still my favorite of all of mine. Just never quits. Great little trike.

Few more pictures of the build with all the plastics and tank on. And will be getting a new seat cover.

Got my motor apart and it was a bent exhaust valve. I had a head that was ported and I decided to use it because the one that was on it had some issues. Had stock valves with aftermarket springs and retainers. While taking the head off the cylinder didn't crack loose while disassemble. So I didn't touch so I didn't disturb the rings. Everything came out great. It had a copper head gasket that was cut down. I did some looking and found one that was the same size. Only problem I have is that it leaks a little oil on the right side of the head gasket, it's not a bad leak more of a seeping leak lol. I will take it back apart sometime. I would like to do a hi lo range cut out mod or find a case that is already done and some other mods. Then I would take head off and do a big rebuild, when I get the money to do it. But I got it back together and the thing rips and runs really good. I will post more pics of the motor in trike later.

Looking great!! Love the polish job!!! ya want to do mine ?????

[1979atc]

Lol I would but I would be 80 by the time it got done! And I was looking at my head that I swapped and I think I know why it's seeping oil, the one had 2 copper gaskets on it that were perfectly lined up with eachother, I only used the one I had didn't know that it had 2, all well ill have to take it back apart someday to do more things to it. Thanks for the input!

Got some wheel spacers for the rear, did some riding on my oval track last night and it performed really good. How does it look? Motor has been running great and the plug is showing very good signs that it's running how it's supposed to. Not running rich or to lean, just right. Been gathering parts for my next build, 1980 Atc 110 with 123cc big bore kit. Will be doing a hi/lo gear box elimination. Will be getting sl 90 counter shaft soon, and have a tranny, carb, and stage 1 cam on its way. Mods to my next build will have 123cc kit, stage 1 cam, sudco intake and oversized carb, hi/lo gear box elimination, BAPP crankcase breather, and plan on getting 4" rear wheel spacers. Will keep this thread posted on the next build. Thanks

I'm looking for a Big Al's Atc 110 allenhead engine case bolt kit. Could anyone help me out?

[John Tice]

Looks like your head spacing is too tight. It appears that your piston is smacking the head. A dab of play dough on the head will give you spacing amounts.

Good luck finding a 90-110 BAPP allen head set.

Here is a good set that is also stainless.
