I have a 03 gade 800 (ZX chassis). Dealer gave me 03 Rev belt by mistake. The rev belt is wider. Before I noticed the mistake, I did notice my sled was faster than ever. Does anyone know why this would happen? I am thinking less belt slip, perhaps. What would be the downside? I did notice some wear on my clutch springs when I changed them at 10,000 miles. They stood shorter on the bench than the new ones and there was wear on the 2nd and third coils. I am uncertain if this was caused by the wider belt or is just normal after 10k miles. I ran the Rev belt 2k miles from 8k to 10k miles on the odo. Once I put the proper belt back, the sled was slower again. Any thoughts?...I am thinking of staying with the rev belt but I am nervous of causing future problems.
