Review on Silver JRL CNC Racing Cylinder Head for 66cc/80cc Engine by Bashar Shaffer

Revainrating 3 out of 5

Looks great, doesn't work as well as I thought it would

If you're buying this to work faster, I don't think it's worth it. Anyway, I was losing about 2 miles an hour. (maximum 35 miles per hour). I've noticed that it definitely cools the motor. I was able to run the engine at higher RPMs for longer and not have to worry about overheating. Definitely looks cool on a motorcycle. 3/5 stars

Pros
  • Impressive
Cons
  • Mostly good, but...
