I thought I had read somewhere on these forums about people using a different pulley. Maybe I'm mistaken.The cost of this stuff is crazy. Approx - Rear Pulley $754, drive belt $583, front pulley $209.I can't believe drive belts are $583. Snowmobile belts are generally $75-175.
I have corrected my earlier post (#51) on this thread. If you replace your Raider's stock, 66T, rear pully, with a 61T rear pully, you will need a 130T belt. In theory, dropping 6T on the rear pulley, would require a 129T belt, which isn't made. A 128T belt will be too short, and a 132T might be too long. So, a 130T should be just right. It's knid of like the Three Bears story.The reason I came up with a 132T belt, for a 61T rear pulley, was the fact that the Strat. runs a 136T belt, with a 70T rear pulley, and the Raider runs a 134T belt, with a 66T rear pulley. So, it would seem that a reduction of 4T on the pully would equal a 2T reduction on the belt. However, I think this might be more of a coincidenza, since Yamaha is the only company that I can find, that makes 134 and 136T belts.I didn't want someone to purchase the wrong belt, due to the posting of mis-information on my part
