correct me if i am wrong, but the throttle valve size determines how big of a bore i can do on my carb. the problem is... i have no idea the size of the stock throttle valve as my carb is together right now and it is really wore out anyway. Anybody know?

I recall seeing a 28.5mm stock mikuni carb before but that have been on the very edge too.
If you aren't trying to maintain the stock appearance and don't mind doing a little work, a keihin PWK is a good carburetor to swap to.

for what having your carb bored costs you could get a real good start on a aftermarket that is bigger to start with, your also going to have the option of a much better design of carb, not that anything is wrong with a miki round slide, that's what i upgraded to is a 30mm round slide, a lot of guys run keihin's on here, they must be good, what kind of mods do you have that your only considering a bore on the stocker?
well i am hoping i do not need a rebore and/or new piston. So i am looking for power overall for the price. my carb is just a leaking junker right now, head pipe is cracked, and the head gasket blew out :|. I was told that the pipe is directly related to the head gasket. So my plans (at the minimal) are to port match the jub with the stock bore, get a bigger carb, new pipe, and thinner head gasket. I have the v3's and a k & n on it already. Plan B would be to get a 68mm wiseico with all that jazz.
