    First post!

    Evening, yesterday I picked up a 1986 Fat Cat. I live in Southern New Mexico, so we really dont deal with a lot of rust! Just sun baked plastics. But this Cat was decently maintained. Most importantly is I have the title for it and it came with a Factory Service Manual. Last week I missed out on a 250R Honda 3 wheeler, now im thankful, this popped up yesterday!

    Its definetly been ridden for 30 years, but its in decent enough condition. The only real concern to me is the tires, they are cracking. Any go to tires I should be looking at. Being the desert we deal with a lot of sand.

    Broken link fixed

    Anyone fitted a better carb to the cat? I know it has a fixed manifold but that could be modded.

    What is standard carb size and how large could you go?

    So would a fcrmx from a crf150r make much difference ?

    So photobucket wants 399$ to link my pics on third party sites now? Yeah that's not happening.

    New Cheng shin c832s

    They are quite a square profile but with air I guess will balloon out

    I would take the carb apart and give it a good clean out, make sure all the little passages are clean and clean the jets. Make sure the float is not hanging up. Depending on the condition it might need a rebuild. Clean out the air filter or replace.

    Guess what I pulled the needle jet holder and no needle jet!!!

    The needle jet was not in the carb!!

    Just the main jet and needle jet holder (which the main jet screws into)

    So now I search for a needle jet for a 30 year old bike - anyone got one that fits?

    Are you sure it's not stuck in there, they don't usually fall out, need to poke it down or tap with a small wood dowel.

    Tap it out from the slide side. It's very soft so use wood or plastic.

    To give the carb a good clean out remove jets and holders, remove air screw, remove float needle.
    Spray out the carb with cleaner and compressed air, every passage should spray through and come out somewhere else.
    Use a old toothbrush on the jets and jet holders to clean out every little passage.
    Reassemble and ride.
    Use a inline gas filter to prevent tank dirt from the carb.

    What about an ultrasonic clean?

    Is that best?

    Slightly pressed in. It should tap out with just light taps.
    It's not imperative that you remove that piece to clean it. Just spray it out real good.
