hey, since the 90 had a shorter connecting rod then a 110, could you stroke a 90 with just a 110 rod? Also are the cams the same on early 110/90? How do you tell displacement from boring you cylinder. If I got a .1mm bore on my 90 what displacement would it be? thanks

 

I have never tried that combination. Mainly due to the fat that even the aftermarket ATC90 stroker kits didn't ammount to much more power than what you would get with a bored 110.
Now, the 110 strokers that Sparks and Powroll used to offer gave you noticable power over a bigbore.

If you look good enough on ebay, serious hopup parts float around on there from time to time. You just have to be dedicated to finding them. A guy had one on there a couple months ago that was bored, stroked, cammed, ported,......and ran on alcohol!! He used the transmission from one of the early model streetbikes that had the manual lutch as well. He used in a race kart frame. It went for over $500
