Finally got my 100cc (79cc) Predator clone kit done! Put on 35 miles over the last few weeks. Got it to 45mph (still has governor). Rides smooth, reliable, sounds good! Sounds like a little 4-stroke pit bike. Had to buy a replacement carb and install new clutch, and adjust valve lash. Pretty happy with it now. Gets lots of attention, especially pulling up to the gas station and pumping gas right into it! Appreciate everyone who helped with good advice.
