    New 1993 SL750

    New memer here, and the new owner of a "free" 1993 Polaris SL750. She is on the way to NC from GA, the original owner gave up on her. No idea of a major problem, just that it stopped running some time ago. ???. The guy is no mechanic, for sure.

    I'm a tinkerer and have a good chance I'll be able to get her running. Hope it is something stupid. I found the site a minute ago and already found a manual. WOOHOO.

    Thanks, guys.

    Thanks in advance for any help.

    What would you guys do with such a new toy?

    Dumb questions...

    I assume this will be a 2-cycle engine? Is it pre-mix or does it have an oiler?

    I assume this is a simple carb? Did they have fuel injection back then?

    Do I treat it like an outboard motor?

    Yup, 2stroke; carb, but no, not "simple" carb. Took me a year to wrap my head around these bizzare little carbs. Very clever design, though, will still work upside-down!

    Fuel injection was around, but aftermarket and very rare! Most likely yours still has oil injection, but it's good to convert to premix.

    Welcome to the Hulk.

    If you found the on-line manual, then you found all your answers.

    I just got to looking at it today... It is pink. I guess that was the Miami Vice era.

    I plainly see one cylinder head is a different color than the other two. No paint left on it. I'm thinking something happened there.

    She definitely has a blown head gasket under the suspicious head. Eroded, corroded, and burned in spots. The cylinder must have been ingesting water from the cylinder jacket. I don't know how long she could have run like that and how well she would have run.

    Otherwise, I don't see any signs of damage to the lower parts. The bore looks good as does the the rest that I can see. Maybe that was the problem?

    Do I get parts from Polaris or is there a distributor you guys like to work with?
