@steveracer16 i like yz more tho lots of power and the water pump is not on the rear axle wich is alote better.. dunno why they diont putt yz instead of cr seriously
My Grand Prix Racing TonyKart CR125 pulls 39.8 on the rear wheel dyno. A stock CR125 moto engine pulls 32 with a good pipe. My GP RS bike pulls 47-48.5 . A rotary TM125 pulls 48-50 when built right. I hold 13 land speed records for engines 100cc, 125cc, 175cc I built all these engines. Records posted on So Cal Timing Assoc (rider D. Cummings)
PS. NO stock 125 moto makes 41hp! lol
Ive been building motors for the top AMA GP riders and karters for years.
hmmm - was it strapped down well enough? Seems like it spinns the wheels on the rollers - could explain the poor reading. But 30,8 must be at the rear wheels, right?
where did you get ur motor mount for ur kx 125
