    newbe has a problem with sl650

    Hi everyone, I'm a newbe that just got his first ski. 92 sl650, starts and runs fine, but I discovered (after getting it home), that there is fuel leaking around the back spark plug. The plug is tight and has the washer on it. Is this a common problem, and how would I go about getting it fixed?

    okierebel, love your screen name LOL. WELCOME to the Green Hulk Forums!!
    Do you happen to have a photo of the leak?
    Have you tried to torque the plugs to their proper specifications?

    I don't have picture yet, but will get you one. It appears to be leaking around the plug itself, I can't see any cracks or other damage. The plug is tight, but I don't know what the torque settings are. Thanks for the reply.

    A new plug get torqued to 10 foot pounds
    A used plug gets torqued to 18 foot pounds.
    Be sure to use a little anti seize on the threads.

    Welcome to the HULK.... Plugs can leak between the metal and the ceramic. I would install new plugs and see what happens. Also do some searching on this site about upgrading your fuel pump and fuel system. That is the biggest engine failure problem with that ski!!!

    Thanks for all the help guy's, I pulled the plugs out and checked under them to see if there were any problems with the mateing surfaces. I couldn't see any problems, used some anti-sieze on threads, and torqued them back down to the recommended 18 #'s, and what do you know no more leak! Got the speed fever so bad, I had to take the dirtbike for a spin!! Can't wait for it to warm up a bit more, so I can get this thing in the water!! One other thing I need to do for sure is to reglue the no skid mat on the back deck of the ski, it was loose, so I took it up and put in in the cubbie so I wouldn't lose it. Any suggestions on what to use to reglue it, and how to get the junk off the bottom of mat to get a good set?

    I always use a pad designed for stripping glue and the such but if you don't have access to the SCOTCH product line, I'd just use sand paper for prepping the surface. Contact cement is what is used for mats. I usually trace the pattern, prep the surface and apply the glue in the marked area. To prep the mat try using some acetone. Put the glue on both cleaned surfaces let it set for about 5 minutes, apply pressure and 'wala' done.
    Check the tech section and you can read the detailed instructions by Hydro-Turf.
