Title: derestricting a zx fever
Post by: steve w hebburn on June 05, 2019, 10:30:09 AM

hi, having recently bought a 1999 zx 50 fever 2 stroke, like everyone, im looking for more speed (. over here in england 50cc bikes are restricted to 30mph by law so 16 year olds can ride them, & car drivers without a bike licence. )  ok back to the questions. i intend to fit a derestricted variator boss, and maybe 5g or 7g rollers, ( which is better? ) i have already joined the 2 green wires together at the cdi. to disable the rev limiter. not going to touch the clutch at the moment. any advice guys ? cheers, steve.

Check out the 50cc part of this forum for performance parts. There are plenty of good posts about 2T hot rodding. I think a performance pipe is the best way of gaining extra h/p and torque. This option would require a richer rejet.
