Terrible product. Do not buy

This set is just awful. I wasted so much energy and spent hours of my time installing it. After checking the compression, I found that the compression was almost non-existent. I bought another set elsewhere and have had great results.

Pros
  • . This is the perfect conversion kit or you can upgrade your 125cc engine to a 150cc engine.
Cons
  • Socket required

Pros
  • 57mm cylinder kit (standard 150cc) Piston kit with rings, gudgeon pin and clamps
Cons
  • I vaguely remember

EGR/Vapor System Replacement Parts

Pros
  • Fits 157QMJ engines with EGR head, 76mm bolt position, head height 2 1/2"
Cons
  • Secret
