we have two 70'S one with stock pulley ,variator
one with the mallosi overange
the stock is best at short to medium tracks
the longer tracks the overange will be faster, if your rider keeps it pinned
but im still tuning

It all comes down to how many rpms your pulling as to whether an overrange kit is useful. All comes down to how built your motor is. The finacially hard part to drr's is that everything goes hand in hand, and needs to be done at one time. pipe, pvl, intake,carb, clutching, bottom and top of your motor.

Case in point, I had a really fast 50 mod last year. During testing before the season I tried it all. Due to not pulling enough rpms, the overrange just wouldn't work. Call some of the very reputable builders in the mini quad world and run it by them. Just my 2 cents.
