Ok, so I decided to shed somemore weight off the ole girl and upgrade to a 520 front/rear sprocket and chain kit -1 on the front. I slapped it all on and made sure there was no binding and adjust tension on the new chain and decided I would terrorize the mountain road quick before I went home for bed. Well as we all know with a new chain, it throws grease everywhere, so when I got back to the garage, I started cleaning her off and did and after-ride inspection. front sprocket=flawless... Chain=flawless, Rear sprocket=Not so flawless... The peaks (pitch) of the sprocket looked like the old one I just took off with 10,000 miles on it. We all know how a sprocket is supposed to look when we inspect em, and trust me, this one isn't holding up.. There are no broken teeth yet, but that's sure to come. I am pushing 81.6 ft lbs of torque per the dyno, so I am not sure what the 520's are supposed to be capable of handling from DRIVEN, but this has me concerned.. I am supposed to be receiving another sprocket from Sam, another 10.net member in the next day or two, maybe I will have better luck with the one he sent.. Only thing I figure, is that the sprocket isn't HARD ANODIZED... Any suggestions?
