    Wolverine X2/X4 clutch mods

    Reserved, stay tuned, but here's a teaser pic (That's the belt in the Primary, notice how much lower it's riding compared to the wear marks, it's right at the lip seal boundary). Note: there's more that can be done, this is just the first stage of testing.





    UPDATE: Weller ECU flash is now the primary solution. Please refer to this thread on SpeedoHealer, which currently is the only solution to bypass the speed limiter until the ECU is hacked:

    Fixed Primary stock wear marks:



    Fixed Primary first cut wear marks, can still mill some more:



    Good for an extra 3 MPH (barely hit 56 MPH). Unfortunately we received 10 inches of snow so I'll have to wait for better weather to safely try again. Will disclose weights used at a later date.

    Even with this first cut, she's like a bulldozer plowing snow compared to stock and I couldn't restrain myself:

    Also to note, we hit this speed with a full windshield and canopy. We also have my X4 ecu programming and my fuel mapping from my dyno runs back in November. Removing the canopy should boost our top speed further.

    Those of you who have upgraded and still have your stock rollers laying around, please inspect them for me. I just inspected my stock rollers (ran in grease from the factory) and I don't like what I'm finding (what you're looking at is flat spotting):







    My X4 has been driven in sub 40 F temps for it's 870 some miles. Most of that has been low speed with occasional plowing, most of the plowing in 20-30 F temps.

    UPDATE 2: the flat spotting is due to the rollers being scalped when they reach the end of the cam plate ramp, which has a sharp edge.

    UPDATE (disregard this update): I believe the flat spotting is probably due to my secondary spring cup being gouged by the guide pins:

    I really don't care about us being the first to hit 60 MPH in a Wolverine X4, but the fact that URBS isn't and that Timmmaaay and Jamie will have a coronary makes my day. Maybe they'll shut up, just for a little while. I hit 63 MPH, but since I don't have it on video (yet) we'll concede to only doing 60 MPH. This is our very first sheave machining attempt. Needless to say, you can get results by testing, or doing research, or both. Obviously we did more research on our first attempt than the other guys despite them having months of testing (as well as an X4 in-house) head start ahead of us.

    It's my sheave, so I care a little, haha. When finished testing, full sheave will be available through Hunterworks.

    Thanks, at this point I'm worried about belt cooling (scratch that, after 3000 miles I'm no longer concerned about it). My stability concerns at those speeds aren't as big. I don't know what it is but she seemed stable once you get past what seemed like a boundary layer.
