The wife's 2014 viper..I was playing around with 2weeks ago, in heated garage getting the hang of how to changing the belt,.... Same belt went back on it 1000km on it....now when it sits at idel it wants to creep ahead like it's driving itself lol,,it ran mint before, I was pushing on the helix 2 weeks ago...now it wants to creep ahead all the time...any thoughts? the yams dealer said gonna have to shim the secondary ,.but I find that hard to bealeave cause it was working good before I pushed the helix in doing the belt things ..thanks

Have you ran it outside since the belt reinstall? You have to run the sled through a range of RPM's under a load to properly set the belt deflection. If that doesn't do it then you will have to remove shims behind the three bolts on the back of the secondary clutch. Yamaha sells 1 mm and .5 mm shims so you can remove 1/2 mm for adjustment.
Also check the clutch springs to make sure one of them didn't brake.

When you put a new belt on or mess with the belt did you pull it backwards toward the secondary to bring it up all the way sounds like that’s your problem

Check your primary clutch, if the belt is flush in the secondary then it's not too tight. Look for a broken primary spring first.

I'd order Schmidt bros comfort clutch kit for it. It comes with the primary spring and smaller rollers for lower engagement. She'll like the lower engagement and it shouldn't brake a spring again.
