Excellent parts, fast shipping and great customer service if you have any questions
This motor really made my ct70 more enjoyable on the road and now can keep up with traffic
Great little motor, performs better than expected. The stock shifter is a little strange, but definitely does the job. I have no complaints, and am looking into the aftermarket shifter
Runs great.
Solid motor. Never had any problems with these 140's. Love the power and reliability.
