I'm going together with a 95XP800 and want to use a Rossier pipe. I would like to hear from anybody who has a clue about jetting, water routing, and carb setup. I also have the original MSD 42251 rev/timing box. Minnetonka4me, did you file that info? I ran into a old thread where you figured it out. This will be a rec rider. Thanks in advance guys.
