Reminds me of when I was (much) younger.... Honda SL 70.... first ran on alcohol, Flywheel put on lathe and lightened, then bored to 90cc (and run on alcohol) Kalgarded, THEN entire cylinder bored out, replaced with a 110 (or 125, cant remember) sleeve and piston.... Ran like a stripped @$$ ape for about 30 minutes.... then tied rod into a knot....
Couldn't make a 110 (or 125) rod fit... so probably only reason i didn't get shrapnel, cause we weren't through trying.... :smile:
(oh.... and in the end, the guy up the street blew us all away anyway,, 650 Kawasaki (3 cyl 2 cycle I think) in a 3 wheeler frame, chopped and lowered (kinda like a big wheel)... you couldn't keep it ina straight line in any gear with the power applied)
