    Angry Stalling in 1st gear

    Hey all-

    Last week I replaced the clutch cable and throttle cable on my freshly rebuilt bike, but now I can't get the bike to take off after I put it in 1st. It always stalls no matter as I try to take off. I can't figure this out.

    Here's a video of it happening:

    I replaced my old clutch cable with a shortened one from Common Motors. I figure it's something with how the clutch is adjusted. My process for that was:

    1- I screwed the adjuster cable where it feeds to the clutch all the way down
    2- I set the handlebar adjuster screw at half-way
    3- I adjusted the adjuster on the side of the case (screwed clockwise past the marker until it stopped, then back toward the marker until I felt a little resistance, almost getting back to the marker).

    4- That was still quite loose. So I backed the adjuster in step 1 out about 2cm until the clutch lever felt decently tight with only about 1cm of looseness as I pull the clutch.


    Any one willing to try and help me out here? I keep messing with the handlebar adjuster screw, but I'm not getting anywhere. Really don't want to just drop it off for a $300 repair after doing the full rebuild myself!

    Hey Phil. Bike sounds good. Make the phone call.
    Clutch adjusting can be a pain especially if it's your first time.

    Well, I haven't test driven it yet (pouring rain), but I think I got it corrected in my garage!

    I put the bike on its center stand and I played around with the clutch until having it in 1st with the clutch pulled/rear-brake depressed didn't stall the bike.

    Now to adjust my idle down to 1200 or so. I'd remove the carbs and measure the openings again....but removing the connectin piece between the carbs is so annoying! Have to loosen the throttle cable a bit and turn the carb adjsuter screws about 1/4 at a time.

    Thanks again you guys!!
