ATC 110 build

[1979atc]

Today I did some more work, got case oil holes filled last night and did some sanding to smooth everything off. Got my seal put in my case half, and I have to get my doner 90 motor tore apart plan on using head and I have to get shifter shaft and keeper out. Other than that I got the crank put it and the transmission together. Donor is at my grandfathers, so I will get it about Tuesday when I go out there. Going together pretty well so far hopefully have it running in the next month or so. Still have to get chain, would like to find more flat track tires, have three bolt rims for them but I need to get those sand blasted and the old tires need takin off. Have a NOS wamulass front tire for the build also. Still need to get a carb and another sudco intake. And I have a Big Al's pipe and stinger to go on this build.

If I decide to paint it sometime I'm thinking about going with a old spray bombed blue my dad used on one of his race 90s he had back in the day, wish he never sold it. It had a Chrome Big Al's pipe like the one I'm using on this build, but only chrome. And had a 108cc kit with stage 2 cam and oversized carb. My father had his friend race it in the 200 class, wouldn't let him be in the 110 class, and he started dead last and finished 3rd. I may have to put a picture on here of the three wheeler, I saw it at my grandfather's not to long ago. Hopefully this build turns out good I love these 90/110s. Thanks

Yeah they are I think they look and handle great. I tore apart my doner motor and got my shifter shaft and keeper out. This motor is horrible I have it sitting vertically right now with brake fluid down the cylinder to loosen up the piston. The head was good shape, so I am able to use it just need to get the valves tore out of it, and port it. Lap the valves and clean up everything then ill be good to go. Bottom end is half way together right now, hopefully be together soon.

The side cover is just slid on there for now I'm waiting on my shifter shaft seal. Transmission shifts and works well. How does the case side look? Thanks

Good Stuff! Those were the days. Grass Roots Racing!!!

I wish it was still those days, I would at least want to race mine once. I have an oval track but only race my brother on it sometimes, anyone know where they race like 70s and 90/110s anymore? Or do they not do it at all anymore, thanks for the input everyone!

Daddio would be the one to ask about the 70 racing around Coshocton. I know a couple places that'll run whatever as long as there's five of them. I'd love to get a group of 90/110's together for some fun. I know Sunset Ramblers in Galion ran a trike class when enough people showed up. I also know a couple other places that would run them too

There are a few small tracks around here but most of the guys are either racing stock cars or dragracing during the summer. We do manage to get a few races in every year though. If you are on Facebook try this link. It's to the O.T.C., Ohio Trike Crew. They have the scoop on trike racing in Ohio.

Maybe I'll have to look into it, kinda a shame all the tracks around me disappeared. My dad is a close friend of the person who owns Fremont Speedway a sprint car track, pictures I posted of the racing is the track. They had that track in the infield, maybe I could do some talking someday and see if they would try to get something put together. Just have to find people to come and race!

I have ran into a problem, my 123cc piston I was told was a 123cc I am pretty sure it is a 118cc piston. My rings I got that were 123cc are to big and the top ring will not even fit in top piston slot. Does anyone have rings for 118cc kit for Atc 110. All I need is the rings not the whole kit. I see kits on ebay ,but no rings. Please let me know ASAP, I need rings! Thanks

What is the measurement on the piston?

[1979atc]

This is what I have on the caliper, but i am not real sure how to read it. But I think the piston is a 118cc. All input is appreciated, I'm learning a lot of you have more knowledge on this type of stuff thank you!

Looks like a +5 90/108 piston. The 90 has a 14mm wrist pin, the 110 is 15mm. The piston on the leftt is a 110/123.
