    UPDATE

    After testing different master cylinders from MAGURA here's my recommendation

    The 10.5 has the easiest pull but it can only fully engage the clutch when the star adjuster is set to maximum

    This leaves no adjustment as the clutch and clutch arm wears

    If everything is new and you don't mind adjusting your shifting pattern and want a really easy pull than the 10.5 master is fine

    For the kit I am recommending the 12mm axial master cylinder

    It fully engages at the lowest setting and has plenty of adjustment as the clutch and clutch arm wear...it has a slightly firmer feel compared to the 10.5

    At this time I'm not going to add my modified clutch arm in the kit

    The 5 participating members names have been submitted and when Jeff lets me know when the kits are ready I will send the codes


    I will continue to improve upon it until I can make it the easiest pulling clutch on the market

    The first 5 users are receiving a discount to compensate for their time so that they can be a part of the continuing development

    Their input will be crucial so that I can improve the product where the end user feels it's necessary

    Here is the new 12mm TurTal/Magura clutch kit installed

    The basic routing of the cable and the placement of the slave and TurTal gizmo

    The TurTal gizmo and how it worx

    The little gizmo is simple but it's very effective at what it does

    It has the ability to flex in any direction to alleviate any chance of binding while maintaining a straight pull

    It is easy to use once the clutch arm screw is in place allowing for quick installation and removal

    The screw is a specific length so that it can be installed without removing the clutch arm

    The nut has a hex threaded insert to keep it in place

    Within the nut is a tiny O-ring....it serves 3 purposes

    It allows the end user to tighten the nut by hand until it bottoms out....this keeps you from over tightening the nut and binding the rod....this also prevents the piston/seal from premature wear on one side of the bore from being cocked in the bore...this allows for long seal life and no premature leaking of the seal.....set the screw and you're done

    It allows a certain amount of cushion as the rod operates back and forth

    It also reduces the intrusion of contaminants into the threads such as grit...grime...water...etc.

    The nut itself also serves as a handle to aid in reverse bleeding of the system

    Fore and Aft Adjustments are accomplished via the slave bolt

    Like a mouse trap the gizmo is basic...gets the job done and will remain trouble free for its lifetime

    Update

    Jeff told me that Magura finished building the gizmo and that he was pretty sure they had recieved it at the U.S. location 2day

    He did not give a date yet


    I think they were shooting for mid/late February

    UPDATE

    Ok just got off the phone with Jeff @ Magura USA

    The latest projected date is that the kits will be ready by spring

    I know I know that wasn't the original time line

    Here's the deal

    When I designed the gizmo I wanted it to be simple and 100% plug-n-play for the end user

    I originally cut a slot in the cap with the hole so you could just slip the rod end into the cap nut without disassembly of the slave cylinder

    As I played around with it I really didn't think the cap could hold up to the constant pulling with that much material compromised

    I didn't do any long term testing to validate whether it would or wouldn't pop the end off I just went with my gut on it and felt uneasy about it

    Since Uralista folks like to tinker a bit I thought the best course of action was to just let them unscrew the rod and slip it through the nut then screw it back in the slave and wa la you're ready to go

    Looking back on it that's not really 100% plug-n-play...98% maybe...but still....no

    What I didn't factor in was Warranty and How Magura would handle that warranty if people were pulling the slave apart

    So Magura Germany has cut a slot into the cap so that now all you have to do is slip the rod in and go

    I told Jeff they can improve on the gizmo however they see fit...after all it is their name and reputation on the finished product...I am merely a humble servant

    They are testing that cap as we speak....I already did the cycle and pull strength of my original cap upon submission

    It's taking Magura Germany a little longer than we anticipated but I'm confident they want to make sure it works properly and is reliable







    P.S. There are a couple of TurTal enhancements to the design that I will post after the original kit comes out
    They will serve to assist with overall functionality

    Given the similarity of the clutch operation between Ural and BMW, would this fit an airhead BMW?

    Magura makes a barrel fitting for the rod

    I don't see a problem getting it to fit

    @TurTal - Please add my User Name to the pool that will be eligible to receive the monthly secret TurTal discount code. I'm interested in the 12mm axial master cylinder, as you recommend above. Thanks.
