A guy I know has a 440 kit on his bike Wiseco 11:1 stock cam, stock carb, uni or twin air filter and stock exhaust. Where should he start on his jetting it had a 148 in there just prior to the 440.
We tried a 152 last night and all the sudden fuel came out of the drain tube in the back side of the carb, but would only do it when gas was turned on reserve, he didn't have much gas in tank. So for that probably float stuck or something silly. Just curious where we should start I noticed a lot of guys running around 160-165 but with other mods cams and such.

Thoughts?
And the only reason for other stock componets is $$$$$$ or lack there of I suppose :)
