    GP1200R rebuild - what would you do?

    Burned up a piston in my '02 1200 GPR (mods are listed in the Sig) so maybe now is a good time to add a little speed... Was planning to fix my little problem with an SBT Top-end kit and then add:

    pro-tec 150psi heads
    rejet the stock carbs
    Jet-works mod

    Does this seem like a good approach while keeping the cost down as much as possible? Does a 1300 top-end just bolt on and if yes, does that make even more sense?

    Thanks much for your feedback!

    How many hrs on the bottom end now? Was bottom end ever rebuilt? If yes was the crank Trued and Welded or OEM?

    Frank - Bottom end is stock @ around 190 hours. What do you think?

    Don't run SBT.....get Prox piston kits...comes with rings, pin, clips etc. 190 hours is getting to the point you may think about having someone like crank works take a peek at your bearings etc....more so if your planning on modding and making extra power.

    Mpeavler - thanks much for the input, would you mind sharing why you would stay away from SBT? I would appreciate understanding the differences. Thanks again.

    PS - The SBT kit is the entire top-end cylinder kit, not just the pistons.

    the quality difference in parts ...from the craftmanship being in question. You can do a search and most .."99" percent of them are complaints about their products. Pro-X piston kits are cheap...very relaible and as close to OEM quality as you can get IMO

    Mpeavler - Thanks again. So you would simply have the cylinders bored locally?

    Most folks know a good amount on these boards. I've been messing with the skis for 10+ years....but I would not say I'm an expert....but I've worked on a few skis.
