So are ya saying a OKO 30mm? PWK starts at 28mm, 33mm, They don't have a 32mm. PJ34. Mikuni has a 32mm
Really any of those carbs will work very well, If I had to choose and new I wasn't gonna ever go BBK, or drag mode I'd stick with a 33PWK. Only as I very familar with the PWK series. Had the 30 OKO hard to dial in, but quad did rip! Ran the 35mm air striker awesome! And now I am sticking with the 33pwk for life!
But really if ya pick up any of those carbs on the cheap, it's a good buy!
Remember if you stay 28-30mm only slight mods to fit carb into stock intake and filter side.
Any larger your gonna need a larger intake about $65 and more opening of the stock air box unless you are running a aluminum box then just a matter of changing the reducer size. Some guys cut a section off of the stock filter side boot and inserted a piece of PVC pipe with hose clamps and then ya just need a silicon/rubber connector from pipe to carb!
