"Heavy Commando clutch"


  

          

greetings

My 72 Commando Roadster seems to have a very heavy clutch. I read (from a link here) that you can use an Atlas clutch rod actuator
for a mechanical advantage (lighter clutch).

http://www.britiron.com/dynodave/ndnsclutch.htm

Has anyone done this, what is the part# for the Atlas actuator?
It has been my experience, when I order Brit bike parts they need
the part #, I do not have an Atlas stocklist.

Also, where can I get a teflon-lined clutch cable for a Commando,
low-rise (UK) handlebars.

best regards

p.s. the reason for this light clutch is, previous motorcycle
damage (my left hand has several pins in it, I can ride for a couple hours
but after that my left hand goes south) I don't really want to
do belt drive conversion

I'll try and think of finding the atlas PN it when I get home.
I should really include it in the article.....

Be assured the clutch pack is made up of components, that if changed, affect the clutch pull.
This is in addition to the cable lube and routing.

Ease of operation is NOT associated with either belt or chain drive itself, but only if a change is made in depth of the basket that holds the clutch components. I remade my clutch bottom plate .050 thicker than stock and it lightened the pull a bit.

Under your circumstances it is entirely understandable to use an atlas lever/cam. It should become a one finger clutch, but you must maintain proper clutch/cable adjustment to insure full disengagement.

Jeff, I haven't used the Atlas actuator, so I can't comment. But I have experimented with stacking heights. It works.

Dave, thanks I would very much appreciate the part#. If I can source the part, I will try this when I replace the clutch cable.

Mike, my thinking is: I want to try 1) replacing the clutch cable as I have fitted the low-rise UK bars (the cable curently makes an "S", you can hear the friction) 2) replacing the clutch actuator with the Atlas part, and 3) I may try using "dog-leg" levers, if I can find some that will fit the controls.

If this is not enough, I will tear into the basket & clutch plates.

thanks!

Thanks! this will be the first time I've actually ordered from the UK, usually I can find parts here. But I have been reading the Norvil ads, and may order a few other bits while I am shipping a box across.

also noticed they have teflon-lined clutch cables

Will let you know how it turns out, thanks
