What next?
 

So I bought this scooter and paid a guy to put a 100cc BBK on it. He said he put a 24mm carb on it, new CDI and a set of up-gears. What is something cheap that I can or should do to this scooter to make it perform better? It performs well, will go about 50mph with good acceleration. And what did this guy mean by up-gears?

if it goes 50 leave it be

Sounds good. Now I just have to get a new tire for the back. Brand new tire is leaking a ton of air already. Opinions on windshield?

Make sure your valve stems arent leakiing. I didnt pay attention to what year your scoot is but they are known to leak.

Scooter is 2013. Sprayed some soapy water on the tire and it's leaking from 3 different grooves in the sidewall.

Doesn't sound like the tire is a 2013... Bummer time for a new tire

Check the valve stem, the valve works loose by times.

I soaped it down and found where the leaks are. In three of the little treads right next to each other on the tire. I put some slime in it and hopefully it fixes it. I feel sorry for the poor SOB who changes my tire in the future. Thanks for all the help though.

Opinions on windshields anyone?
