    Question 110 camshaft vs 90 camshaft

    Does anyone know if the cam shaft for the atc 110 and atc90 are the same part? I am putting my head back together after a valve job and notice that the rocker arms are not lining up directly in the center of the cam lobes?

    I had to buy a used cam because I bought this trike without the top end, so I been obtaining parts wherever I can. The head and the piston cylinder seems to fit together fine. I may have the wrong cam????????

    According to my listing a 72-78 atc 90 and a 79-85 camshaft is the same so I dont think that you should be having any problems

    Unhappy

    ooooh, I think I just answered my own question, I did not have the cam sprocket bolted on so the cam was sliding into the head more than it should have?

    Oh well I'm just getting too excited about getting this thing back together. Think I'll go drink a cold one, mow the lawn and return to the project later. Sorry for wasting forum space.

    The 110 CDI cam is longer where the advancer attaches. You can trim it back to run the points advancer in a 90.
