Amazing product!
Great upgrade for moped, it will get your speedometer to break because it will make it go so fast. I had a yamaha zuma '01 and this increaed my top end from 37 to 46. Acceleration was increased tremendously. Pull back on the throttle and it gets so much more HP it will pop a wheelie if your not careful. Ive put on around 3,000 miles with this kit, and its running better than the original engine. Would recommend, however dont do what i did and dismantle your engine because you think you know what your doing. Had to watch alot of youtube to get this sucker bsck together. All in all, great addition and upgrade if your somewhat mechanicaly inclined. Best kit for the price.

Meh
More power but.... You can't use the carbon reeds because they don't seal in the cage. It also does not come with the gasket and oring for the reed cage.But it does come with a large oring that isn't used on this engine lol

POOR CASTING
The casting at the bottom of the cylinder was so thin it rolled back and folded over. Casting pieces in the crankcase mean I now have a full teardown rather than just a top end job. Poor quality, pot metal cylinder.

Huge increase in torque off the line 0-20 is fast and burries the speedo and then some
Did not like it has a new rist pin but does not have a new roller bearing have to use old one

10 more MPH
10 more MPH and worth every cent. Easy to install and super stoked on the extra power. Don't forget new 90 jets, Athena Scooter Roller Kit 15mm D x 12mm L 5.6 Gram rollers and remember only swap out every other roller, 3 old, 3 new. Also, adjust your air fuel and idle screws. Finally I pulled the internal snorkel out of my breather box for 91 octane and my set up works great.Best bang for your buck to increase speed, torque and fun!
