Hi everyone, My name is Cameron and i have an issue with my CVT on my 2010 450 grizz.

Issue is that the secondary works a treat in park and neutral. however when under load…Drive, Low or Reverse. it barely moves and i have to rev the daylights out of the bike to get it to even take off. I have tried to spread the secondary apart a little which i could do…was a little tigh, and when i did it stayed there, (didnt spring back onto the belt). I am assuming the secondary spring needs replacing. Can some one please help.

Note the bike was sitting for almost 7 months in a shed due to previous owner trashing it. Just had to replace both fron CV axles, both steering nuckles and rear bearings.

Any advice or help is greatly appreciated.

Cameron
