I titled my 1980 CT70 and needed to go faster. This engine certainly did the trick. Runs great and sounds amazing.
Had a wiring question and the guys at Bart Moto answered my text in a couple hours. ( white wire from harness plugs into second yellow wire from engine)
Lightning fast shipping too! Thank you bart moto!
Great engine! Just make sure you get correct carburetor and jet it properly and an exhaust to get the best performance.
