OK I've run a lot of kits, but this is my favorite so far. Lots of torque. I put one on my ZA50 and another one on my E50. The E50 takes off nicely and hits 60 mph with 18x37 gears. The clutch slips until about 30 mph so that may not last long at least under full throttle. On the ZA50, my gearing isn't as tall so it tops out around 55 mph but it's quick to get there. 19mm dellorto with 76 jet, 375 degree head temps up hill and 330 on flat.
