Hi all. I just picked up a 98 600 grizzly that’s in pristine condition. Very tight bike with no cosmetic damage. But, as most of these do, it’s burning oil heavily and has some really bizarre knocking and slapping noises.

I got the top end off. What a treat… Rounded 3 of the valve cover bolts and had to drill the heads of the bolts off. Very tight clearances because I left the motor in the bike. Real fun! Lol.

My question is about the decompression setup. I noticed that when I push on the weights to open up the decompression/ raise the cam pin, it takes very little effort. I can’t imagine it being normal as it just feels so loose and flimsy. It barely wants to return. Is that normal? Or do u think that I need a new spring under the pin? This setup is all new to me.

Any helping greatly appreciated. Thanx.
