    Fuel Supply and Carburation
    Seems like i may never. Thought id have some fun building a custom in my spare time. Pick up on that runs, mod it, tweak it... have a little fun like when I was a kid. But, it's turned into a he'll storm with my limited time to work on it. I've posted some carb issues previously and since...
  3. Rebuilt, Rejetted Carbs 81' CM400T

    Fuel Supply and Carburation
    Ive read the main sticky on rebuilding rejetting for pods, 125 and 90s.... and followed it to the T; less the 127.5 jet for straight pipes. I jetted with 90s and 125s and running pods off the back of carbs, no stacks, and headers only. So I really didn't follow the main sticky to the T. I get...

    Fuel Supply and Carburation
    Hey guys, My superdream is having problems and seems to be running rich. Always has sooty black plugs and i'm wondering if the jet sizes are wrong, but I can't seem to find any information on what stock jet sizes are. I've looked in the OWM and online but no luck. Thanks for helping Cheers Isaac

    Miscellaneous Discussion
    Hi everyone-- New member here with a 1974 CB200. Has only 4,700 miles, and purs like a kitten(when it's running). Sometimes when I would ride, once I would come to a stop the bike would shut off. Note: I've been only been able to ride with the choke on, so I think I just need to adjust my carb...

    Fuel Supply and Carburation
    Hello All, I have put pod filters and high-flow mufflers on my CB360T, and immediately noticed a lack in power when going full throttle (which I of course expected). So I got my hands on a jet kit from 6sigmajetkit.com and have put the following into my carbs: - 78 Primary jets (changed from...
  8. Removing Jets! (Have searched around!)

    Fuel Supply and Carburation
    Can anyone point of the most straightforward and non-destructive way of removing the jets? I assume mine are stuck with 46 years of gunk in them, but I still can't see which side I should be pushing them out from now that I now that you shouldn't be using a screw driver even if it looks like...

  12. 1971 CL 175 main, slow and needle sizes

    Fuel Supply and Carburation
    I have been working on a 1971 CL175 scrambler with off idle hesitation. Purchased this bike for the wife's first bike but the hesitation is stalling the motor on her. The carbs were rebuilt by the previous owner and I'm convinced the wrong jet, needle and slow jet were used, the wrong kit. The...
