Needing some information from anyone who has played around with gearing to make a servi car have better hi speed.
i have experiances changing gearing on WR,s for racing and understand that.
Looking to find out what others may have done to servi cars working within their limited power and heavy weight.
What about the rear sprocket, i have not diss-assembled the rear end to know, but can i fabricate a different sprocket to change my gearing ??
