Hopefully in a few hours I will know the issue with the motor.Maaaaaaaan, this is why we can't have nice things! A replacement 125 is a great choice, the 140's are a pretty proven motor as well. That said, you can't beat an original built motor. Hopefully you can figure it out.
I saw that they do! Sad part is if I want a 140cc with semi auto I can only get them with electric start it seems. So i may do a 125cc semi auto but throw a performance cam in it.Bummer about your engine, but tbolt has 140s in stock!
Gave this a shot and still have the same issue. Headlight goes out when applying the brake. So weirdThe Tail light needs a better frame ground. Try a jumper cable from the engine block to the tail light to test if it is the frame ground or a more rare case where the tiny jumper wire between the reflector and base of the tail light unit is broken. You will be able to tell if touching the jump wire to the tail light unit solves the problem, or if touching the reflector makes it work. The reason it is doing what it is doing is because the tail light ground is being made through the headlight positive wire ( you just switched from parallel to series wiring.)
