Moby decomp cable

My brand new cable snapped at the cylinder. It looks like vibration caused rubbing and cut right through the cable.

Is this a common issue?

I haven't looked too close, but probably going to shorten it, knarp, and reattach it.

Is there a work around to the decomp? I've never owned a bike with a decomp, can I ignore it and leave it shut? Is it really required to start the bike, will it be more difficult?

Maybe just leave the cable off all together and use a piece of string or screwdriver to start/shutoff.

I don;t think you'll have an easay time without the decomp. unless you go to like a kickstart or pullstart.

You could simply use the kill switch, (left bar) Be prepared for the stepped on duck sound the horn will make as the engine dies, this is "normal"....It's French! :D I use the decomp on Motobecanes, not on my Hobbit, but it really helps to have.

theres a small metal nippled cup that protects the cable close to rubbing area.

Re: Moby decomp cable

You dont always need the decomp on a well tuned bike, however it is helpful in starting a cold bike and also very helpful for stopping the bike.

On the Moby decomp valve the sheath of the cable pushes on the shepherds hook and the bullet of the cable is under a fixed anchor. The shepherds hook is actually the spring that keeps the valve closed, pushing it down takes the spring pressure off the valve so it opens.

SO to rework the cable you do not need to snip and knarp it, disconnect the lever end and trim the sheath on that end, reassemble into the lever's knarp.

Adjust the cable so there is 4 or 5mm free play on the lever.

There is a step down cable bushing, see Myrons Moped.

Re: Moby decomp cable

Whatever piece protects the cable from the little hook is missing.

It snapped and is now frayed on one end, both ends missing their knarps or soldered equivalent.

I'm able to get it started by pushing it, and can easily use a screwdriver or tool to open the decomp to shut it down.

^ No kill switch?

Re: Moby decomp cable

I bet between this thread and the one I started I'll find some little hint how to make the new cable work.....all the parts are there.
