I have a 1992 Mach 1 with a 617 and I am thinking about changing my rotary valve. *I would really like to know what is involved in the switch. *What do I need to do not to screw this up? *Do I have to change anything else for this "mod" to work? *Any info from someone who has done this would be great. *Thanks
There is one special tool that you will need to get from skidoo. It is a degree wheel that you use to time the valve. Other then that I am not totall sure. I am going to be doing this soon so I will let you know how it goes.
