    Heya

    I dont wanna be a forum hog or ne thin, but im really sweating on getting this bike working sweet before uni goes back and i run out of money and time. (my dear bommadore is broken too!).

    Just wondering, i snapped a clutch cable the other day, and im just waiting on a replacement, no probs there. But while i was waiting for the trailor on the side of the road i thought i could just yank on the cable to engage the clutch... apparently not. i pull on the cable which moves the arm thing... go to click it into gear... nup, just pops into gear and stalls. like i wasnt doing anything. Is it just i cant pull it hard enough? go i hope so.

    Cheers felles

    You won't pull the clutch by hand, there is a lot of leverage gained in the clutch lever.

    As hawkeye suggested... if it's a matter of getting home and avoiding a trailer call-out then you can actually rollstart it in 2nd gear and then clutchless shift up and down to get yourself home. You don't want to rollstart in first as clutchless shifting from first is almost always a rough and violent experience for the gearbox.

    The quick and dirty way of explaining clutchless shifting needs to be done in two parts as upshifting and downshifting require almost reverse techniques.
    Upshift: whilst accelerating with near full throttle, in one motion you need to shift up and snap the throttle half closed then open again. If you did it properly the bike with almost seamlessly continue to accelerate; if you did it badly it'll judder as the chain absorbs the shock.
    Downshift: whilst decelerating with the throttle closed, in one motion you need to shift down and snap the throttle open then closed again. Downshifting is more difficult to get right; and arguably does more damage to the gearbox than upshifting.

    If you do need to stop at traffic lights just make sure your in 2nd gear and it's reasonably flat ground (or downhill) and just roll start it again when the light goes green.
