    OK, one more SLT780...but THAT'S IT!!! Ooops, I did it again!!!

    OK, so back on the 3rd I bought a parts ski per the below...

    I went and bought ANOTHER SLT780 tonight...that is three total...this one really is just a parts ski though. No way I am going to try to build this one up to running.

    Hopefully this will end my spare parts obsession.

    $265 and the only things I KNOW are busted are the MAG cylinder, which has the mag piston arm protruding thru the starboard side, the reverse bucket is busted off, and I am sure the crank is toast.

    Everything else looks good, hopefully this much damage will keep me from fixing it...plus I cannot afford another shoreport right now.

    Can't wait to see if the MFD works.
    Well, I found and bought ANOTHER one...sheesh...I am going to go change my sig file to "You have an SLT780? Can I buy it?"

    It will be Wednesday before I can go get it, I'll post details at that point.

    Oh, and there's one near Orlando with low compression for $100 on Ebay if anyone is down near there. The guy wouldn't wait for me to come get it in October when I will be down there anyway.

    Just curious, but if I decide to go the 780 route, would you be willing to part with any of your parts? This will be completely reliant upon the condition of the cylinders/pistons when I finally get everything apart and how much needs to be replaced on the 750 end of things.

    Maybe, I have dupes of some items now. Extra cylinders and carbs, reeds, some electrical stuff.

    I need to get a look inside the engine in this ski and see what can be salvaged.

    I winder how many there are in Georgia total?

    Hmm... well congrats on the pick-up, BTW. And if I need a full top end, I will most likely do the 780 swap. I need to do a lil more research on the actual gains though... cost / benefit analysis kinda thing. Also, I need to re-look-up what all is needed. I assume cyl. jugs & pistons but I vaguely remember reading that it also requires a 780 exhaust manifold.


    Anyways, you whould throw up some pics of all your ski's

    So tell me about the SLT780's. There's one for sale in my region that I keep thinking about. I used to own a Kawi STX-15F. Anyone that has ridden both, how do they compare?

    I have never driven anything else. But my brother used to have a pair of smaller skis that had been hopped up. He swears the 780s handle better and are more stable. I would guess if you are into wave jumping for height the SLT might not be the best plan.

    Mine both do 50mph topped out. I have them de-tuned to about 48 for safety.

    They have big 14gal tanks and reverse also.

    They do have an odd dead-zone just over 4000rpm, but I don't spend much time there.

    Looks like the parts ski MAG locked up, yanked the rod out of the piston, and then shoved it out the cylinder wall.

    I don't think I'll be wanting that cylinder from you...

    Yee Haw! Must have been a fun ride... Did the crankcase survive?
