Hello all! So a while back I traded loneXB a tail light for is 2004 sprockets/pulley from his Firebolt. I ordered a new 04+ belt and yesterday I installed it all. I get everything swapped and my belt is tight!! really tight, like it took me and a buddy about 45 minutes to pry it on there. (but tried my best not to bend or damage it) it really seemed like it was too small!! we finally get it on there and go for a test ride, she now makes a loud whining noise from the primary / pulley area at about 2k rpms in first and constant on the highway. but to hear on the highway I have to duck my head down to the right. (really sounds like the 1125R on decel!!!) but I also have no primary cover on it just yet, so not sure if it always made that noise and since the cover is off i can hear it or ???? Now the big kicker is going forward the belt spins fine, but I push my bike back about 3 feet and the belt creeps over on the pulley and if I go a few more feet it would pop off completely, but forwards its just fine........ I have no clue why it would creep off when backing up as well as I have no clue whats causing the noise?? any experience out there????? The bike has never been down and had no issues with any of this before doing the belt upgrade. (front and rear sprocket, idler pulley and belt) Thank You!!!!!!!!! -Robert Hall xblights@yahoo.com | ||

Robert, I have never heard of that problem, but I would try loosening everything ( Axle, rear pulley, idler, front pulley) and then re-tighten everything to spec. per service manual. It sounds like an alignment problem. Robert | ||

Robert Not sure about belt sizes but that sounds too tight and might cause bearing/wheel failure. Also there was a post concerning the 1125 belts backing off when rolled backwards when very new. Joe | ||

Did you obtain the 2004 idler pulley and bracketry as well? Pretty sure that it is different. Current issue of Fuel provides the complete parts list for a 2003 to 2004+ secondary drive upgrade. Thanks to Mr. Abe Askenazi for that!  If so, how did you go about mounting the belt? Last thing to go on should be the idler pulley with the belt already in place. The belt tending to walking off the rear sprocket in reverse is not unheard of. If I recall it was attributed to a misaligned idler pulley, at least in one case.
