carb size

Sure. It probably wont fit your stock intake boot though. Youll have to get a different intake manifold, and youll have to modify your intake boot to fit (stock carb is a 26mm)

Im running a 28 mil PWK and I had to get a different intake mani and modify my stock boot.
 
you can modify the manifold too. if you have a dremel or a drill with a drum sander. just hollow it out slowly until it fits. what kind of carb is it?

That's odd Luni, I just ran my stock manifold for the PWK28. I did cutoff the rubber bumps up top so I could rotate it just enough to clear the clutch lever tho.
