First I work at a scooter shop as a full time Tech. Piston clearance on a Gy6 is minimum 0.004" recommended. The piston to Cylinder clearance on the set you sold me was 0.0005" way to tight. The Cylinder must be honed 0.0035" to achieve the proper minimum clearance then I will fit the rings. I wanted a drop in kit that didn't require work before installation. If the clearance is not redone to Spec. the parts will self-destruct in less than 10 miles. My kit was honed then installed The scooter ran great and had good power.

I was expecting some more power for my 50cc Tao Tao out of this big bore kit but what I got was a fire breathing scooter. This works like I would have never have expected. I had it installed by the motorcycle shop by my house and even they said they could not believe how much of a difference it made in the power, torque, and top end of the scooter. This kit buries the speedometer needle. I am very impressed with the kit and I would defiantly recommend it to someone who wants to put a very powerful edge on their 50cc. If i got on the scooter not knowing it was a big bore kit, I would say it drives just like if not better that a 110cc or 125cc. Combine this with a performance exaust to help the more powerful engine breath better and you have yourself one mean scooter. A+++

You need to maintain ur scooter that's all. Oil change, gear oil change, and valve adjustment every 1500k it runs like a top! Get a cdi orange in color NGk plug . I have no problems with My scooter. I get 165 k per gallon . Which is a little over 100 mpg. I have 21,876k on my TAOTAO ! U just need to maintain! I decided I was going to order this kit ! My buddy just got the 72cc 47mm kit it runs better then mine so I had to up him with this 83cc 50mm kit this kit is a good one for twain it's better steel ! And the only way u can tell a diffence . China 08/10 on jug. Twain o8 on jug! Happy scooting ! Adjust ur valves like I said u will like ur taotao again! Plus it's so easy YouTube has all the videos u need.
Before I was 30-35mph up hills which was better then stock 20-27 now with this kit I'm 45 all day ! I drive 40 miles a day wow I was missing out on that extra 10 mph! Ps I live in the mountains of Appalachia. Maintain ur china parts it will love u for it!
