Well I got some weights off eBay that where supposed be in good shape, which they are but the person didn't list then as the right weight Grrrrr. Anywho just checked them and they are 53.8g as apposed to the 52.7g they where supposed to be. Would you guys leave negative feedback? Now comes the important part, I'm ready to grind the weights down to 53g to start trying to tune me sled, my question is where do I take material off? Don't want to mess them up. Running a new belt, new yellow grn primary spring, new primary clutch, I'm adding these weights. What should I shoot for weight? Figured 53g would be a good start as 51.5 was the weights I had.
