Machining grooves out of inner clutch hub?

    My rekluse pro inner clutch hub has some faint grooving (bought it used). It growles, groans and snatches off idle. I've talked to them on the phone about it a couple times, and the consensus is that it could be the grooves in the inner clutch hub. The longer I ride the bike in the day, the worse it gets.

    Is it reasonable to think that I could have a machine shop take off a few thousandths from each half-circled shaped "row" all the way around the hub?

    I'm not ready to shell out $200 for a new center hub just yet.

    Because of this statement I don't think the grooves would be the culprit. Makes no sense, neither the inner hub nor the steel plates should be affected by extended use.....at least I don't see how.:excuseme: Have you checked the wear limits on your fiber plates?

    ehhh... well, I didn't check the wear. I put it in, and it started doing it. Clutch was fine before the rekluse.

    My statement about worse thoughout the day may not be accurate. Let me rephrase: It doesn't do it cold, but once I have a half mile or so behind me, I'll begin to notice it from a dead stop. It then SEEMS to get louder one more time after some riding (that may or may not be happening though).

    The first time I called, they said it was normal with synthetic oils. So I swapped to Rotella. Same thing noise an actions, no difference.

    FWIW, Bike has 14 hours. 4 of those with rekluse (used).

    Also... I don't want to spend $200 on the inner hub only to find out its NOT the problem... so anyone think I can get away with machining it a little?

    I had grooving in my inner hub on my 01 wr250. Took them out with a die grinder, small file and sand paper. Use the die grinder to level the sharp edges of the groove then file and snap paper to smoothe the "tooth" of the hub out. Worked great. Going on 3 years now with no clutch problems.

    Hmmm:thinking: looks like that's what I'll be doing.

    Thanks!

    i always just take a small file to it....

    but that dont really sound like your problem...
    usually it wont disengage totally...growling sounds like a bearing or something

    I can see how it would get worse as you ride because the oil gets hot and thins out and is masking the issue less.

    As for re-machining the grooves this will make the drive plates that interface with this hub looser and then you will gain these notches back faster. The only real solution is a new hub. Filing will gain you some rides but you will be right back here in 10-15 rides IMHO.

    You might get away with filing them slightly and then having the hub hard anodized. That will provide some thickness back on the part and also is harder than aluminum while it lasts. I think that hub is plated already right?

    That was my initial thought.... I didn't check on the cost, but I imagine it would cost half as much as a new hub (new hub is $199). I didn't want to drop that on a "worn out" part, but it may be worth investigating.


    It may well be, I'm not sure. I asked them how many hours I should expect to get on one, and didn't get a good answer... they said it depends on heat. That's probably true, but doesn't help me any. lol.

    eh well... I'll probably just get a new one in the next few months.

    thx for all the help! :thumbsup:
