Clutch Alternative to the Clutch Lever

    I'm just wondering if anyone here has ever come up with an alternative to the clutch lever?

    Rather than have the lever on the handle bar, have it mounted like a gear shifter somewhere on the frame?

    Also, has anyone try using a hydraulic lever & slave cylinder instead of the cable method?

    Just looking for some different ideas on my project.


  2. How about an electric solenoid activated clutch? (not practical but different)
    I would think a hydraulicly activated clutch would be nice.

    I'm going to be installing bearings to try to help with the slop and friction a bit.
    I may(most likely will) put an O-ring between the clutch cover and clutch lever to help keep debri out.
    I hope I dont have to end up trying to make another clutch pivot shaft.

    I got my bearings in the mail today and now I'm just waiting for the extra clutch cover and pivot shaft to get here.I'm sure it has been done before but I'll give it a try myself.

    The stock setup is very sloppy on mine and it is new so I can only imagine how much worse it can get.
    I did grease it during the install but it is sloppy.

    I'm hoping with some bearings in there it will be good for just about forever.

    IMO, the stick shift clutch would be awkward....I want my hands on the control.

    not sure if the clutch leaver all comes at the same angle ,,i removed the nut on leaver and since it sits on a spline i change it so that there is less angle on the clutch cable ,, that helped ,,i also seen no use for the long spring that covers the cable that only added more tension , i then added a spring from the clutch leaver to the other side of the motor to re leave more tension need for so much tension on the clutch ,, just make sure that if you add a spring to help re leave some of the tension that your clutch is not slipping ,,my guess is that i took off about 25 percent by adding a spring and it works good and no sign of slipping ,as time goes on the clutch spring may lose some tension so you should keep a close eye on the amount of tension ,

    the amount of tension ,and the poor angle,,plus the sloppy fit of the clutch leaver ,, can injure your mussel in your arm ,,the amount of tension on the spring could operator the clutch on a gray hound bus ,,a long way from a 70cc what were these engineers thinking about ???

    dax has a new longer and angled's durn near a straight shot to the adjuster & the added length gives you more leverage, i personally like it.

    opinion: the small spring helps to keep slack out of the clutch-cable system and is a plus. i've always used it and still have my original clutch cable....over 3000 miles on it now.

    I have pondered an alternative to the clutch lever a couple of times and have made something I think would work. It's like a suicide clutch...well, actually when I made it, it was a brake. It would work just fine for a clutch lever though.

    On a side note, I have started my next motered bike build. Bent the tubing for it last night.

    I highly doubt that any REAL engineers worked on these, I'm guessing they are more of a copy, the chinese products in general are pretty much copies and no R&D goes into them unless a name brand company is over seeing all aspects of production.IMO

    I thought about a brass sleeve bushing but I wanted to try a real bearing so I wait for the new parts to get here, I guess I could just go out and install them in my clutch thats on the bike.

    japat100: i haven't noticed much difference in pull or adjustment. when i have time, i'll take new pics of the lever & arm positions under proper adjustment. remind me if i forget for too long.
  12. HI,
    I was thinking about the new clutch lever too....Does the relatively small change in length really make that much difference?...I think it was only
    1.5 CM longer on the lever arm..

  13. :grin: I thought about making a slightly shorter lever just so I could get a positive engagement/disengagement of the clutch.

    For me the clutch is not hard to pull in (I must have vise-like grip :grin:) and even my wife can ride it without any trouble but then she does ride her motorcycle and quad.

    I also thought about making a lever that was sort of a semi-circle, with the cable riding on the edge of the semi-circle which would help keep it aligned with the cable holder but I keep thinking that that is just a bit much.

    My plan is to minimize the slop and friction and shorten the lever 5-10mm.

    the whole clutch leaver,was poorly design from start to finish ,, the adjustment near the handle bars is junk. the play on the side cover leaver is crazy you would think they would have enough sense to at least dril the right size hole ,,the angle of the cable don"t make sense ,,the amount of tension in the clutch alone is at least twice as much as it has to be ,,and on top of that they give you another 2 spring to add to the tension ,, theres only one answer ,,,let it be known to the sellers and importers that this is not crazy but this is retarded ,, a 5 year old kid would at least drill the right size hole ,,so i hope the sellers and the people that import these kits read this post and get off there as,,,,and do something ,,there is no excuse for such sloppy work ,,and would cost nothing to make big improvements ,maybe what we need is more sellers that will fight for improvements .

    no reason why a little smaller hole would cost more then a bigger one
