    XS650 Clutch Worm Actuator experiment & tidbits

    Hi again, just a few words in case it's useful. Did another 25 miles on twisty, hilly roads on a warm day so got the engine pretty hot. Shifting is better at all speeds I think because the clutch releases with just a dab on the lever. And now say at low speed I can slip the clutch accurately if...

    XS650 Clutch Worm Actuator experiment & tidbits

    Yes the original is well protected. Actually pull effort seems similar but maybe more of the energy gets where it's supposed to go and more consistently. I'm cautious about saying to go for it until I've done more miles under more conditions but it looks good so far. And sure you know, everyone...

    XS650 Clutch Worm Actuator experiment & tidbits

    There's not much space between the mech and generator case but yes, a tin cover with a gap there for clearance could work. I haven't cleaned inside the case yet but this seems the cleanest area so that'll probably help.

    Just to say, I didn't look into this much, just picked a part and wanted to try it. I'm certain a more scientific approach would work better!

    Jim, no, none! And the grease might attract dirt but the steel is pretty hard. I'll chance chance it and add an item to the maintenance diary...

    XS650 Clutch Worm Actuator experiment & tidbits

    Cool, I'll do some more miles and try to confirm it's good. Adaptor is just a thick 45mm washer with holes for the original mechanism screws. 50mm washer would be better as the 2 holes are right on the edge but would need grinding to clear the generator case. Then 3 tapped holes for the...

    XS650 Clutch Worm Actuator experiment & tidbits

    I'd tried a hard to make the clutch work better but still had the usual stickiness and mushiness at the lever and loss of travel with a warm engine. The ball mech has little flex so I guess more lever movement makes it to the pushrod plus it works smooth giving very good modulation. And with the...

    XS650 Clutch Worm Actuator experiment & tidbits

    The eBay listing just said 5 speed, part number 550512 but googling that seems to confirm it. It's on an adaptor plate as i didn't want to mod any xs parts. The cable arm cracked when I tried to bend it a small amount - the case hardening goes deep, hence my ugly version. And I added a short...

    Hello. Just swapped in a royal enfield ball and ramp mechanism. Only done about 30 miles but feels really good so far.

    Removing clutch springs.

    Not had much success improving clutch drag so today I took out two of the springs (done this before on a Ducati) and now have an extremely light lever, easy neutral hot or cold and very progressive engagement. Didn't really abuse it but no slipping yet on a carefree test ride with hills and...
