My grizzly has 9200kms. and uses about 1/4 qt. of oil every 200kms. I,m thinking of boring it and
putting in a wysco piston. Any one else have this problem and what do you recomend? Other than
that I love my machine and have hod no problems.

 

my brothers does this too. he uses synthetic in his, and i told him to go back to reg oil. it made a small differance. thats a good ammount of miles though. maybe time for a 686 or 770 kit, heehee.

 

Has anyone installed a piston? Which is the best to use and what size? Really would like some feed back. Allso
is there a better intake valve that I won,t have to adjust so often.
