Decided to do the Kawi 454 front pulley and step up the gearing a bit. There were some truly nasty ones on Ebay. New one on Bandit with the AMA discount was only $90, so I went for it.
Kawi pulley weighed in at 6+ ounces more than the stock Suzi-Q. Whittled down both sides to match the dimensions (thickness and offset) of the stock. Couldn't control myself, and drilled a bunch of holes as well. Still a few ounces more than stock, but much closer  
FWIW, I cut it on the lathe with a carbide insert tool. Pretty easy, although I'd guess the inner surface of the spline was hardened because it sounded and cut nastier in that area.

I'll probably slot the leading edge of the axle slot in the swingarm to make it easier to put the belt on.
No biggie, just more stuff...
