The mechanic that was going to put this on told me that it was missing the bolts and screws that was needed to complete the job so I didn't even use this 80cc Big Bore Kit I went ahead and put a hundred cc on my bike I wouldn't use is Big Bore Kit if I had to do it all over again too much stuff was missing

I order this kit to replace my old worn out BIG BORE kit. First the piston in this kit is only 47mm not 50mm like it should be. Second the head is a stock head. tiny tiny valves. I bought my last kit on ebay and will go back to ordering from them. This was a terrible purchase

Some parts are for an 80cc. Some are for a 100cc. So basicly the kit is put together incorrectly. I do not recommend this seller or kit.

I will tell you one thing rebuild the bottom end first because, the top end 80cc will give you more rpm and that's awesome 👌 if your engine can handle it..The 80cc top end is very easy to do if you can read 📚 and have a little wrench handling skill 😀. My scooter went from 45 to 65 mph some times 70... It's also smart to have good tires and shocks because speed is great 👠if your bike can handle it 😀...Be safe and have fun buy it, ps the equipment was built very well and everything fit perfect 👌. Buy it...
