The Details

What’s inside

A curated mix of frequently replaced fasteners for typical service tasks—CVT cover bolts, cylinder studs, and drain hardware among others—so you can button things up without hunting individual pieces.

Compatibility

  • Primary: GY6 QMJ157 150cc
  • Also useful: Some pieces fit QMB139 49cc (varies by application)

Why this kit

  • Convenient backup hardware during tear-down/reassembly
  • Great to replace rounded, rusty, or missing fasteners
  • Saves time vs. sourcing individual bolts/studs one-by-one
Important Things to Note
  • Assorted hardware: Contents may vary slightly. The photo is an example of the kit makeup.
  • Verify fit: Designed around QMJ157. Some pieces may fit QMB139, but not all.
  • Install tips: Clean threads, match lengths, use anti-seize where appropriate, and torque to spec.

Keep a small organizer tray handy—label by location (CVT cover, head/cylinder, drain, etc.) to speed up reassembly.
