    1998 GP800/GP1200 Carb Rebuild

    Recently purchased a 1998 GP800 and 1998 GP1200. The GP800 runs great, the GP1200 runs a big sluggish compared to the GP800 and seems to be quite smokey and the engine doesn't seem to run as well and smoothly as the GP800 (sorry for my non-mechanical terms).

    Since these are my first skis, I have been told to rebuild the carbs on both since they are long overdue. I'm quite handy, but never have rebuilt carbs before. I do want to save $$ and get to know the skis so I don't have to pay someone to do maintenance on them. I hope I'm not getting myself into too much trouble. Is this something that's better left for someone experienced?

    If this is doable by the average person, which kits do I need to buy and where is the best place to buy them? Are they normally available locally? I want them by this next weekend so I can try to rebuild by the 4th of July for some water fun.

    Thanks in advance...

    Not difficult to do. First, search the forums and download the OEM service manual on PDF. Then it's just a matter of removing the carbs, taking them apart, cleaning and reassembling with the new parts. do 1 at time so that if you forget where something goes, you have another for reference.

    I would only buy genuine mikuni carb kits. They cost more, but they are better than the after market stuff.

    make sure you get the right kits as well

    GP1200 will have SBN carbs GP800 will have I body carbs.
    GP1200 will need 3 kits and GP800 will need 2 kits

    Thanks guys for your replies... looking to get them soon. Do the Genuine Mikuni kits sell locally anywhere? Or is it best to order online. If online, where is a good place to order that is pretty good on prompt shipping?

    You can get kits many places even ebay
    They will be in a Mikuni package
    GP1200 has 44mm Mikuni SBN carbs GP800 has ?mm Mikuni I boby carbs.
    I think 44mm and 46mm I body carbs use the same kit but make sure.

    Good dealers and PWC shops will stock mikuni kits, but bring some vasoline They can be found on ebay for as low as $25ea. for the sbn kits. I buy them whenever I see them. Retail usually runs about $45 for the SBN's. I body kits are a little more, just not sure how much more.

    if you hit a problem, gimme a call..can do em with my eyes closed by now.
    get an impact driver from harbor frieght for cheap and save yourself stripping out the kidney screws. Mine is sears, but i saw cheap ones for low use at harbor the other day. Use vise grips sideways to break loose the outside screws, then unscrew with a #2philips.
