Guys!!!!
Bitching will get you nowhere here.....
EVO had my SW and blew a belt with 8 miles on the odometer.....8!!!!
Testing in the yard with no snow. I knew the stock clutching was too heavy and belt squeeze was too much. Put in #1 clutch kit, then #2, then #3, then #4 and #5 with no issues with blowing another belt...so I thought "Must have been a flaw in the belt when EVO had it....#*$&@ happens"
Ran the piss out of my 8JP belt and after 600+ miles of hard off-trail, back to back fast speed runs....the belt popped on me while I was showing off in front of some Cats. The bang was so loud...instead of laughing cause I blew a belt, they were concerned I was hurt.
New 8JP belt and now after 1,200 miles. It was time to make some fast speed runs on revised #2 clutch kit. At 130mph GPS, the belt blew in half and actually pushed the side panel out with the belt "sticking it's tongue out". The reason why the belt blew was because the belt climbed over the inner sheave and was pinched between the engine and clutch. How do I know this? Because my gearing only allows me to run about 116mph....but I am overly machined for overdrive. There isn't even a magic-marker mark on my primary anymore.
I have machined both my clutches, set my offset to 61.2mm...and can honestly say when I found out the coil bind was happening, I thought that was it. Machined clutches for friends and has it got better? Hell yes!!! Are we or they still blowing belts? Yup....but now it's after a few hundred miles.
Tried different springs in the secondary and the ones that have less wire diameter will knock off mph on top end. We all have our dimensions checked over to make sure the offset distance is correct. Trying different clutch kits. I don't know what to try anymore....but I believe my sled will not blow a belt if I re-gear. These are my results and have tried everything.
