Great Item, Great Price
Good price and fast ship
This cylinder head kit is a complete solution for 110cc engines. Everything needed was included, making installation straightforward. The quality is excellent and it runs smoothly. Fast shipping and great value. Very happy with this purchase.
This cylinder and piston kit brought my Yamaha two-stroke back to life. Great quality parts, easy installation, and it now runs like new. Highly recommended.
It fixed 2 problems--AC going off and on (breen light too). Ac was always pulling outside air in--now I can switch to recirculation. My husband had no trouble with the install even tho he is disabled.

Grill fits well
Removing the OEM seals were harder than I expected. However, installing these new ones were WAY easier than I expected! The new clips lined up perfectly, even though I didn't hear all of the clicks. They are firmly in place and look great.
The quality and fitment was on par with OEM. It was an easy install with no issues.
