    Ya know ya keep dancing around it but what you need to do is.

    1. take the carb off and clean it

    2, take the clutch apart and figure out what the hell is going on in there. Chances are the plates are just stuck together. pry them apart, sand the steel plates a bit and put it back together.

    3. take the clutch cable off and lube the hell out of it if it can even be brought back to life. I would suggest taking the entire cable off and soaking it overnight in brake fluid to try and knock the crap loose inside the housing.

    Do those 3 things and youll have a whole lot better idea what is going on inside there.

    If you cant figure out how to work on the clutch just post up some pictures of what your puzzled about. Somone on here will know how to get you thru it. But untill you get that side cover off you wont know what is in there.

    While searching for a sprocket for my Lifan 125 (they use the larger output shaft and not the early Honda-style splines) I noticed on one of the pit bike parts sites that the "outer rotor" ignition I mentioned in an earlier post apparently does come with lighting coils. It's simply a smaller, more compact version of the larger flywheel/stator combo used for years. This means that the Pitster motors equipped with this setup can be used to power lights (with a suitable rectifier/regulator). If you throw in the towel on the SL-90 motor and decide to swap to another motor keep this in mind. Might even be a good idea to ask whoever you order from if the motor you're buying comes with a lighting-suitable stator. The early Pitster motor I have on the shelf came with a big flywheel but no lighting coils on it's stator.

    Thanks for that info, I am starting to lean towards a Lifan, but not quite ready to throw in the towel.

    As for the bike, got a little time to work on it Saturday so I cleaned out the carb and put it back on. Noted one of the bolts was improper and the bolt stripped on it's way out!:rolleyes Appears that just the bolt stripped and not the carb manifold screw hole on the head. I had to remove the whole metal tube thing with the carb on it cause there was weird bolts in the end of the manifold where it attaches to the carb that had nuts on them and would be a PITA to remove. The gaskets still there, looks a bit old and dried but seems to still be effective.

    The carb seemed to be pretty clean actually, but sprayed some carb cleaner anyways and blew compressed air through the jets and made sure they weren't clogged.

    Put it back on and the bike wouldn't even attempt to start! But with the stripped bolt on the left it probably was leaking air now. It was already hard to start before anyways. So I'm gonna go get me one of them new bolts.

    But then I decided to start pulling it apart, it won't run now anyways. I kicked it and kicked it and not even tryin. Sometimes the kick starter feels like to easy to kick and then it gets hard like its seizing and then goes back to normal.

    So I pulled the cover off to see the clutch but right as I did my friend who I'd planned to ride with on a 2 day ride pulled up on his bike. So we looked at it and I didn't see anything to obvious, so I decided to start disassembling the clutch next weekend. I'll keep Y'all posted.

    I know this is a year late - did you replace the SL90 engine in your bike? If you did, I'm interested in buying it (and I'm in California). Let me know - thanks!
