I agree with Bill, they don't call 'em BikeBANDIT for nothin'! $35 for 
a headstock bearing set is pretty reasonable. You can get them on ebay 
for about the same price. One of the bearings is standard, the other is 
not so after buying one cheap std and one expensive OEM bearing, it's a 
wash buying the set.

I like Sprocket Specialists ( for my 
sprockets. They don't have a listing for the coutershaft sprocket for 
the GPZ. The one for the ZRX1100 is the same as ours. They have both 
steel and aluminum rear sprockets. I get a steel C/S sprocket and Titan 
Tough aluminum rear sprocket for a little more than $100 shipped to my 

As for the chain, I prefer the DID brand, 530ZVM2 (about $150) for the 
best, 530VM (about $110) for a HP OEM equivalent.

Good advice from Bill on the valve adjustment as well. Measure 'em up, 
see what you've got, and swap around the ones you can. You may end up 
only needing a couple. See if your local dealer will swap you the ones 
you need instead of buying new ones.
