    I have replaced my stock shifter with an RFX and a Driven shifter. They both seem to get loose very quickly and I can barely get them tight enough to eliminate the slop. What's the deal???

    Same with Hammerhead. Lasted two rides, and it wouldn't shift anymore. Slipping on splines.. I emailed hammerhead and they wont reply...

    Replaced with a stocker, and no more problems..

    My stock lever does that, so I use a longer bolt with a nyloc nut on it. I tighten the bolt down as much as I can ( stainless ), then tight the nut down as tight as possible. And I check it often.

    Get a steel one that will fit on there. Also make sure there is a gap after tightening it. If not remove it and us a circular fiber wheel to remove some of the gap and make it wider. Aluminum shifters always seems to stretch to the point where they don't hold anymore. Steel shifters seem cheap and heavy but last much longer and can be bent back many times. I like steel shifters.

    Solid advice, the cause of most issues. Also Motorhead's advice of a longer bolt with a nut is a good call. I check my shifter bolt and kickstarter bolt pretty much every ride.

    Pretty standard for a lot of people on any brand making me think that shaft needs to be about 2x the size it is. Its somthing you smash your foot on with little tactfulness.

    I think I may have found the problem with the shifters I mentioned in my first post. I put both shifters side by side and found that they both have a deep notch worn into them as you can see in this photo. These shifters make contact with one of the bolts on the clutch cover. I filed away some material on my RFX shifter to add some clearance at the offending clutch bolt and remounted it. I only have been able to get out and ride once, but it's still nice and tight. I hope this is the cure. DSCF0560.JPG

    Just just bought a cheap steel YZ250 (same spline) shifter off ebay I'm going to modify. The steel splines should not come loose and I can bend it back when it bends. I ride gnarly woods and would rather have the bike weigh slightly more than have failures.

    I had the same problem, coat the inside of your shifter splines with Loctite retaining compound. (I used 609) Put your shifter on, tighten up and your set. Mines been good for 50 plus hours.

    Cheap steel is the way to go. For around 10-15 bucks you cant go wrong. I have never once had mine come loose on any of my bikes. And how much weight are you really saving? I mean really......lol its a dirt bike lets not overthink it

    And that weight is about as low on the bike as it could be. And you can bend it back if bent, and is does not strip. Steel has it's place on a DB.
