Trail Bikes 141 Big Bore Kit, Mikuni VM26/Kit for Chinese/Import 124cc Engines
Kit includes the following:
- Lightweight aluminum cylinder with steel sleeve, 52.4x55mm bore and stroke with 14mm piston pin.
- High compression piston with rings, pin, & clips (replaces your low compression dished or flat top piston)
- Head gasket kit
- Genuine Mikuni VM26mm Performance Carb
- Intake Kit
- Jet kit with 3 different sizes
- Throttle Cable
- Air Filter
- Cam NOT included
This will make a huge difference in performance over your stock setup and is a very quick and easy upgrade as it does not require case boring. We found the right level of compression for increased performance while also keeping reliability in mind. For additional performance, this kit includes our new Race Cam as well as the Mikuni VM26 carb, intake kit, throttle cable, and air filter. NOTE: This kit will only work on Chinese 120cc engines with a 52.4x55mm bore and stroke and a 14mm piston pin.
INSTALLATION NOTE: Don't use the original o-rings between the head and cylinder (not needed) but do use the large o-ring at the bottom of the cylinder between the cylinder and the engine case at the oil return.
Cam NOT included
