Well I did it again. Blew the same piston (clutch side). This time major damage. Looks like I am going to need a new cyclinder, pistion etc. There appears to be a hose on the bottom of the crank that looks like it is there for pressure equalization. Where it attaches to the bottom of the crank it broke off. I don't know if I can have it welded back on or not. Anyhow I am learning the hardway. What I need to know is how you remove the clutch. I have the engine ready to come out so I can split the crank, but I don't know if I need a clutch puller for this type of clutch or not. My friend has one for a Ski-Doo but he doesn't think it will work on a Yamaha. He said some clutches will come off with a rubber hammer. I looked at a couple of places for clutch tools but they only went up to 2001. I am hoping the crank shaft is okay. It turns really easy, but with the bottom of the cyclinder gone that is a lot of aluminum in the crank. I don't know the cause, but I read some guys have had a lot of trouble with Kimpex pistons. The connecting rod pulled right out of the piston and broke the bottom of off one of the sides of the cyclinder.
Yes you need a clutch puller bolt.
Where in MN you located? I've got a minty 02 Viper for sale, but better yet if you are in the right area I may be able to point you in the direction to borrow the puller you need.

Viper
I borrowed a clutch puller from a friend, worked great. I am now shopping for parts. I need a cyclinder and piston. I am interested in your Viper. Can you send me some details. Price, mileage, condition, accessories? I have a line on one in Rush City I was going down to look at next Friday 3/19. My e-mail is dkruelle@midco.net. I am in International Falls so it is a drive to anywhere.
