Sorry for not getting back to you. I am out of the country for a week. I have posted pics of the pulley and found some more info. Eurocharged was not able to tell me which one it is, but it was purchased 10-2011(so I am assuming the first version). After digging deeper I see that this pulley had problems with springs on other posts but did not see a definitive fix other than changing to a different pulley. My plan was to re-shim and keep a close eye on it, then if it gives me problems change to the stock or different pulley. Is shimming again worth my time or is it doomed to fail?
