Theres no way for us to tell you that. Look at whats in there then add 10-12 %. Have you done your rollers and clutch springs?

You don't wind jets in and out, that'll be your idle adjustment. To get at the main jet you have to take your carb apart and it will be inside the float bowl area.

As said look at the main jet size and add 10%. The exhaust should have come with new rollers and clutch springs. If you don't change these then your bike will never run properly.

I would put a post on Scooter Shack as there are more ped heads there who may have done the mod so they can tell you straight away roughly what jet to fit.

Google plug chop because thats what you need to do after rejetting. It's not that easy to set a 2 stroke ped up so if you feel uneasy about doing it, take it to a garage. Plus your ped will no longer be legal if your 16.
