    Just got a '93 SL 750, wanted to introduce myself!

    Hello all,
    Just picked up a 1993 Polaris SL 750 with a ShoreLand'R trailer. Ski has an unknown but high number of hours on it. Haven't gotten a chance to check it out yet but allegedly it will start and run ok, but has little to no power. Ski had a top end rebuild in winter 08/09 and began having the no power issue in late 09 and has sat ever since. Ski was garage kept in the winter, and stored out of the water on a shore station and covered when not in use. Exterior is in fine shape, and the steering/trim were working fine.


    My plans:
    Diag. the power issue & address (According to my fathers untrained eye all of the pistons are intact)
    Carb rebuild - most likely Watcon kit
    Fuel Pump and lines
    Oil lines and fittings
    Fuel tank valves

    Is there anywhere I can find out the differences between the '93 SL 750 and the laster models? I have checked most of the stickies and the polaris repair website/wiki/knowledgebase. Thanks.

    Hopefully I can be in and out of this with a running ski for under $300 + the purchase cost. Oh wait, it was free... lol.

    I think the only real difference between the 93 and the later model SL 750s was the 148mm jet pump and the digital displays used in 94 and 95. 94 used the round MFD and 95 used the oval MFD in the handlebar pad. I always thought the 93 was kind of cool looking.

    That orange life preserver was worn during a rescue drill. In all of the other pictures the operator (which may or may not have been me from a few years ago lol) is wearing a propper Type III? USCGA PFD

    I just got my second 780SLT running, I have $300 (purchase) + $370 ($200 cylinder swap from SBT and $170 WATCON kits) in it total.

    That is reassuring! I am HOPING to not have to do a top swap, but if I do, I will most likely do the SBT exchange thing.

    Anyone ever heard of or use Group K Products? http://www.groupk.com/index1.html

    They have an SL 750 "kit" that allegedly nets 6 MPH for $750. http://www.groupk.com/p750.htm
    Are these mods good for that type of gain? I'm sure I could do all of that work locally for less money.



    Lastly, is the K&N Flame Arrestor any good? I searched and found one thread that compared a few FA's, but the results were relatively inconclusive.

    Thanks,
    -James

    Personally, I vote to stop trying to find ways to spend money on it and get it 'right' and then take it from there.

    I am actually de-tuning mine again now, as attempts to lean out for speed did not pay out much...back to safe and happy for me.

    6300 RPM and 48mph is just fine with me and I will spend my money on gas, oil, and ice cream for the daughter at the marina.

    Though I do have an admitted problem with hunting and buying spare parts.

    Actually I am trying to work a trade for a rifle on ANOTHER SLT780...sheesh!

    Lol between my two bike builds and school I don't have money for many mods. I was more asking because I stumbled upon that Group K site by accident. As far as the K&N I ask because I generally replace the air filter on all of my vehicles and was wondering if it is worthwhile for HP and MPG gained. Also, I can get a brand new K&N F/A for $12 shipped, so it is a minimal investment.

    My priority is 100% to repair and revitalize this ski. It was plenty fast when it ran well, and I mostly want reliability out of it.

    You will most likely find that you can have someone bore your cylinders and buy a new set of pistons for less than the SBT exchange.
