well you probably know this but i figure it cant hurt, just in case you dont have any left over to measure. They are 13.5mm in diameter, and i think the weight is floating around somewhere on the perf tuning section.
You could try macmaster carr... im looking right now, you can get 17/32" = .53125. which is damn close to 13.5mm = .53149". Thatd probably work. But of course you can only get those in steel.
Anyways, i just got a varplus from treats and for the cost it was an awesome investment. Good alternative to trying to tune the stock variator. people complain that you have to disassemble it to change the weights, but after a few tries you can have your variator off your bike, in pieces on your work bench, and back together again in less than 10 minutes. not so bad.
