    I'm in the middle of replacing my clutch, and there's no signs of an oil leak around the flywheel. It's dry as a bone in there. I'm aware of the "while I'm in there" belief, but I'm a member of the "if it ain't broke don't fix it" camp, so I'm stuck whether or not to replace the main and oil pump seals. I'm looking for some convincing either way. What do you guys think?

    You realize that if you don't replace them, they'll start leaking within a month just to spite you. :D That said, if you DO replace them they'll start leaking within a month just to tell you that you shouldn't have messed with something that was working fine. Damned if you do, damned if you don't. Have fun with that.

    I'd skip it.

    You'll have the gearbox out in no time when you go back for the seal(s). :evil

    You don't say how many miles on this gem? I'd be tempted to leave it if very low miles but I know how to do the seal and have the tools so it would also not be a problem to put the modern seal in. So, yeah, if this is say under or around 30K miles I'd leave it. (that figure is really not important) If you do leave it and it leaks a month later it can leak for awhile and you will be an expert at removing the trans the next time you have to pull it.

    Something that riders may not understand. A leaking rear seal does not usually get oil on the clutch. It just leaks and makes a bit of a mess on the shelf. If you wipe it up it may not even drip much because the shelf can hold a lot of oil. What I'm saying is a leaky seal is not an emergency. Older guys like me have had bikes and cars that used more oil than gasoline. :lol3

    If it doesn't leak there, it will leak somewhere else.

    If that doesn't leak, some other piece of shit that you own will.

    Sorry if I'm transposing my life onto you.

    Pretty sure the bike has more than 30k on it, and the shelf is dry.
    I think I'll trust my gut, leave things be, and deal with it when the time comes.

    I've got an old '67 Land Rover that leaks like a sumbitch. That's next on my to-do list. Until then I'll throw another piece of cardboard under it and call it good.

    The Rear Main is not that big of a job. IF it's a bit seepy, OR if it's been in for many years and miles OR if you're planning an RTW trip, then I'd replace it. Otherwise, get it when you get it. Example: I last replaced my RMS in the mid-80's. Doesn't leak even after all these years and miles. However, I'm planning a "Send_It_Off_To_Southland" clutch refurb later this year and I'll be sure to replace the RMS and oil pump cover o-ring. Reason: mileage+years+transcon trip.

    I call it "between the dog and the fire hydrant"...

    Same difference.

    My .02 cents,I have probably gotten myself into more trouble(especially when younger) by not knowing when
    to quit tearing into things that weren't the reason I was there in the first place.
    I am with the just fix what's broke people.
    There will be just as many arguments the other way.A judgement call.
    Do what you decide and live with the results.
    Years ago the $$$$$ decided.
    Good luck either way.
