anybody else experiencing noisy lifters on there 02 grizzlies? had mine adjusted at 20hrs.i now have 42hrs and there noisy again. is this common?

 

Grizzlies usually like to hibernate during the winter months and don't like to be bothered. Your Grizzly may be getting very upset with you if you keep bothering it.

Seriously though, is it a constant noise or just when you start up? Are you running the correct oil weight and plenty of it? If these are ok I have heard of a problem with the valve clearance on the intake side likes to get out of adjustment. I would check the clearance and if you have to adjust them try using lock tight on them.
