I used this motor in a street legal '67 cl90 dirt/street tracker build. Using the stock lighting coil, external mounted oil cooler and VM26 mikuni carb.
It. rips. It is such a fun little screamer on the road. And the motor is flawlessly bulletproof. I have just under 5000 miles on the motor and have done ZERO motor work, not even a valve check. Only regular oil and filter changes.
A great motor. Great value. And really good reliability.
Would recommend 100%
