Thanks. Yes it is from a super combat and it is in good shape. In fact I have two of them but one of them has been modified with a bar across instead of the yokes. It could be restored easily though. Thanks again.

I have one. It doesn't have a roller.

I have a center stand for a super combat that I'm trying to figure out what it is worth. I can't find any others for sale to compare with. Anybody got an estimate what it might be worth?

Thanks. If it did'nt quite clean up at the very bottom would that be a problem?

I need to have my cylinder bored. Right now it has a .02 over piston in it but it's quite abit out of tolerance. I messurred it with a Sterrett inside mic and it messurred 50.57 mm at the top and 51.04 at the very bottom of the sleeve. Can I go .04 over or should I go .05?

Thanks for the info. Does anyone know the Dia. of a stock ace 100 piston. In inches if you could.

The specs say .004 clearance between cylinder and piston in an ace 100. Is that on .002 on each side or .008 overall? And where is the best measuring points for wear and taper in the cylinder? Above the ports or down to the base also?
