Just wondering if it is possible to take a clutch off a 1997 xc 440 and put it on a 85 indy 600. Why you ask? Because I am trying to narrow the problem down on my 85 600. What Iam trying to do is see if it is a clutch or carb problem. IT IS BOGGING AND WON'T EXCEED SPEEDS OF 60 MPH. Carb or clutch? Oh ya, do I need a different for the 97 if I want to take it off. I have one for the 85 600 but I am not sure if it will work on the 97 xc 440 clutch. The clutch on the 600 seems to be good (rollers and buttons) any suggestion on what weight should be in it and spring.
