    Pro 785 Carbs on SL750 question?

    Hi,

    I'm in touch with a guy who's got a set of Pro785 carbs and intakes for sale. I want to put them on my SL750. Will I need the reeds as well for my conversion? Reed spacers? Did the reed spacers come stock with that ski?

    Also, any tricks to this swap, or is it just a bolt-on and go kinda thing?

    Also, what's a fair price? He's asking me what I want to pay. I don't want to steal them, what would be fair?

    Thanks,
    Michael

    At the time I got my set, I paid about 500 for everything. That did NOT include the rebuilds by Randy.

    Prices have fallen a lot since then. But really, it all depends on how much HE sees as fair.

    I would offer him 200 and see if he bites.

    The pro reeds would be better than your stock ones, they are longer and are angled towards the cylinders. Spacers were stock on the pro. The throttle cable connects on the rear of the manifold, where yours is up front. You will need the cable from the pro or a 780. I paid 225 for the carbs manifold, and f/a.

    No tricks, just bolts right up.

    Definately get the reed spacers .

    Get the reed cages for the PRO as the stuffers match the carbs better than 750s. Wouldn't be a bad idea to get Carbon Tech reed petals at this time too.

    You will need the longer throttle cable like star mentioned.

    Get the F/A to match if you can also.

    To sum it all up, you'll need:
    PRO F/A
    PRO carbs (prefer 98 and newer)
    PRO intake manifold
    Reed spacers (780 or PRO spacers will work)
    PRO reed cages with stuffers (or AM like V Force)
    Longer throttle cable from 780 or PRO

    I've gotten the carbs, F/A, and intake for around $200. So, maybe offer him $250-300 for everything. That would be a very fair price IMO.

    So what I don't get is why Partsland doesn't show a 1997 785Pro?

    http://www.partsland.com/index.cgi?N...&P=Polaris-PWC

    Strange, huh? The guy I'm communicating with says he has a 97.

    I read in one thread about the 97 and 98> carbs being different internally, that the jetting won't be the same. Can anyone confirm this?

    I have the 97's. They have been tough to tune, but considering all the changes to my ski, its no wonder.

    That is correct Delegem. Don't be afraid of getting the 97's, since Star and myself are using them on our projects currently. It's just suggested that the 98 and newer are easier to tune.

    The internals are different between the carbs. 97 uses normal jetting like 180 mains with 82.5 lows.

    The 98 and newer uses a reverse jetting with smaller mains and larger pilots. Something like a 120 pilot with 65 mains.

    You can see this posted in the online manual in the tech section under 785 PRO.

    Carb differences.

    The 98 & Newer carbs are tons easier to tune. The 1997 785 Pro came with reed spacers, and you will need them for the 750 cases. If you can find a set of 1998& newer carbs, they are the way to go!

    Randy
