If u read my post in the vector section u will find that the 08-09 vectors do the same thing, I have taken my clutch off and ran engine, it sounds the way the sled should sound like, nice and quite and the great 4 stroke exhaust sound, I have researched this alot and have found that the cranks in the08-09 vectors have differnt spline thickness than the 05-07 vectors, they dont rattle nearly as bad as the 08s,presuming u have the oring kit installed in the earlier vector clutches Supposedly yamaha got a different supplier for the 08-09 cranks and they were made up with thinner splines . I took my buddies clutch off his 05 vector with 8000 miles on it and on his sled the clutch is real quite, bolt it on mine and it rattles as bad as my clutch did, Take your clutch and rotate it left and right real fast and u can actually hear the clunking of the splines on the crank and the stub shaft that the clutch bolts to. This is a major f... up on yamahas part Im waiting to here back from some service rep on this issue, They are aware of a problem, but to remedy this problem would probably bankrupt them,by having to put new cranks or stub shafts in all the 08-09 nytros and vectors So when it comes time to trade our sleds in we better not here that oh our sleds are to rattly we cant trade that in.
