ATC 110 build

[1979atc]

Been wanting to share this with some of you for awhile, and today I could finally get a picture of it in the daylight. My father's old modified race bike, it all needs put back together. This is a fully suspended bike, This thing is very wide, wider than legal limit I was told. The motor that goes in this is a stroked 210cc 185s motor. Huge stage 2 cam, 32mm carb I believe went on it. Had a supertrapp full exhaust system and a lot of other goodies. He still has all the old parts that went on it. Packed in our several barns of parts, lol. We plan on restoring this bike someday, or get it all back togther and running again. Has been part for awhile now, ever since I can remember and I'm 17 now. Thanks!

My father told me it has been apart since about later 1980s, what is also really neat about this bike is he said he raced it in the SilverDome in the early 80s with Mickey Dunlap. Just if we got enough space, we could drag it out and start rebuilding it.

Ok back to the 110 build! The first 110 on this thread I decided to upgrade the carb setup. I was first running a 19 mm carb. Now I'm running a 27mm carb! Now it really breaths! Lol. Next I will be redoing the whole clutch pack. Brand new everything, clutch friction plates, metal plates, and springs.

I need a little help. On my second 110 build I'm having a little trouble with the head gasket sealing. I used copper gasket sealer and is still not sealing correctly. I can't seem to figure out why it keeps leaking. When it's running its blowing oil out and bubbling out at the same time. I have never had this happen before and have built several motors with no problem. Anyone have suggestions how to get it to seal? Thanks

Did you put a new rubber seal in? The circular one that goes around the lower left stud dowel between the head and cylinder.

Yes, the rubber seal was in there and it was new. I always double check myself putting that seal in. Lol I used every gasket that came in the top end gaskit kit also.
