    Hydraulic Clutch

    Years ago I installed a 2" Rox Riser and a 1" Precision Machine Riser on my 07 TT Lightning. This allowed me to sit almost upright for long distance riding/cruising. To make this work I had to install the longer Uly clutch cable. The longer Uly cable is harder to pull than the shorter stock cable.

    Looking to reduce clutch lever pull a bit. Does anyone know if Magura or other manufacturer make a hydrualic clutch lever for 03-10 Buell's?

    Anyone know anything about thbis hydraulic clutch system?

    Hi mm,

    it seems this guy: https://www.buellxb.com/forum/showth...ghlight=magura is quite happy.
    To me it seems that 40% gain could be a little optimistic, but for sure some gain must be there.
    I read some of your previous posts:
    Do not stop to ride just for your left wrist, as far the right one is working well!
    Just joking, but just in case I will hate a scooter like clutch.
    Much better I would ask somebody to build for me a system with an electric actuator (solenoid) proportionately governed by a rheostat on the clutch lever.
    I don't know if something like that has already been done for Buell's Bike, but for sure it can be done.
    Just need to see if such a strong solenoid 12 Volt can be found within reasonable dimension and weight, otherwise it will be needed to add some leverage,
    but still if needed it can be done.

    Hey mmcn49! Been awhile, how's the hand?

    Actual (luggage scale) testing of the Magura found the clutch pull to be the same, and that makes sense considering the power needed to actuate the clutch is the same whether mechanical or hydraulic unless you change the ratio (length of pull) and they don't You would lose the actual cable drag #'s but a new cable should be super easy. No magic there, power is power.

    Pingel makes an electric shifter that slams the trans between gears. http://www.pingelonline.com/prodcat/...d-shifters.asp. But honestly, you can do clutchless shifting yourself between gears up and down by practicing your throttle application*.

    Adding a quick shifter is cheap and easy and will take care of upshifts:https://www.buelltooth.com/quickshifters.html. I LOVE mine.

    But none of those address your real problem of holding the clutch lever in for a long time, like at a stop light. This does.

    http://efmautoclutch.com/street

    It combines centrifugal release and normal clutch. Really not a bad custom piece for $695+exchange.

    *Motorcycle "constant mesh" transmissions were designed for clutchless shifting without damage.
    For upshifts, release a little throttle pressure (still slightly accelerating) while putting up pressure on the gear shift.
    For down shifts while decelerating, add a slight amount of throttle while putting downward pressure on the gearshift.

    Get it right and it's as smooth as using the lever, especially in the upper gears. Start practicing going between 4-5, then 3-4-5, then 2-3-4-5. The lower the gear, the bigger the ratio change so while learning, make sure you are going straight and your speed is proper for the gear you're choosing, not just banging gears to practice

    IMO

    Hi Cooter – Thanks for responding and asking. What a wealth of information.

    Had two wrist/hand surgeries and two months of hand therapy since March. Stitches from the second surgery were removed last Thursday and things are looking up! Finally, no pain and a stronger hand!! Hopefully continuing hand exercises will keep it going for a long time to come. The hand is still swollen a bit from the surgery and the incision is still healing but I'm on the mend.

    Didn't know if the rod end of the salve cylinder had enough surface area to give it a mechanical advantage over the cable, (longer clutch lever travel for an easier pull). Guess not.

    And they cost over a grand.

    Watched several you tube videos on quickshifters. Had no idea BuellTooth made anything like that. This is going to help a lot and will have “She Who Controls the Purse Strings” order both pieces as soon as I finish typing. This will cut clutch pulls by 40% or more.

    My problem is pulling the clutch and to a lesser extent holding it in. I've been practicing pulling the lever at the very lower parts of my fingers. I've adjusted the cable so there's quite a bit of slack in the lever, but leaving enough pull to disengage the clutch. This seems to be working.

    I know about clutchless shifting. Did it on the Enduro bikes racing through the woods decades ago but not so much on the Buell's. That will probably change on downshifts when the BuellTooth is installed.

    In closing want to say I learned a lot about RA/Osteo Hands and Fingers over the past few months. One group of exercises called “Tendon Glides” are simple but unbelievably effective. They are not strengthening exercises but the fingers are stronger and they work a whole lot better. If anyone is interested PM me and I'll send the exercise information.

    Thanks for the information Cooter, I really appreciate it.

    Glad to help keep you on 2 wheels

    If you haven't bought the quick shifter yet, PM me
