Having issues with a juggaverter on a modified 196. Plenty of power. 7,000 rpm cam, good torque but seems to just max right out. I'm running 5.4:1 for more top end but it just runs out stupid fast. This is on a mm80 GPS race day bike. Is it possible that with the 14cc head and cs cam that I'm just winding the bag out of the thing? Somethings not right. I'm getting similar results with the same motor on 19 tires and 60:1. Maxes out till it just slips the darn thing and then revs past but that's with a loose belt! Why would the small bike do this? Am I too fat?? Really??
