Carb question

[Timmer]

I have a 22mm kehin carb on a 90cc on replica motor. So its pretty much the same as the 50cc with an 88 kit on it. I was just wondering what kinda main jets some of you guys are running on your motors this size with the bigger carbs and where I can get them.

I have a 20mm on my 88 race head and am running a 85 main. But this all reallly depends on your elevations and such. Here is a good guide to help you tune your bike in good. http://ministothemax.com/hop_ups_carb_tuning.htm
