I have a 91 Formula MXE 470 with 144 studs on OEM track. I rebuilt the engine last year (after the crank blew) 40 over oem pistons, milled 10 thou off heads, and instaslled UFO's in 34mm carbs (rejetted to match) With all this I've gained about 25km on the top end (and stronger through out the powerband), but what I want to do is gear it for more bottom end grunt. I don't care about loosing the top end so much because it wasn't always there(so I'm willing to sacrafice some of the top) My riding style is somewhat agressive (on a limited machine) So I was wondering if anyone has geared this machine, and if so what do you suggest? I should add I'm looking to avoid clutching for now. (As I still have to repair the Rear drive and a few small things to the wifes sled before clutching)
