what size carb for 90cc?

[oldyeller]

What is a good size carb to put on a viper 90?..The engine is basically stock right now with just a set of boyeseen reeds and a uni air filter...I will probably be doing more upgrades in the future.Is it possible to get a carb small enough to work well on my nearly stock motor now and yet will work later if I get a pipe,higher compression etc?

I think alot of people use a 24mm. Best bet is to get with Billy Holt, he can help you out. He did my sons motor before the season started and it's performed well and has been very reliable. He has always had the time to help me on the phone with jetting and clutch questions too.
