    The type of grease really isn't particularly important. Basically the thicker and stickier the better! I'd also caution against greases with a high molybdenum disulphide content as this can in fact build up at the point of contact of the rollers and actually promote scuffing.

    The main problem isn't the type of bearing or the loads applied to them and how they cope, it's mainly water intrusion and the fact that there's nothing coating the cage or rollers to protect them from it. While the seals in the frame are adequate, (As long as they remain on their registers!) the Achilles heel of the system is the rubber seal incorporated in the cone of the RS bearing itself. These are an odd design and while 30205RS bearings are available in the aftermarket the type and position of the seal on the center race is different on the ones Guzzi uses and their ability to actually seal in the frame is dependent on the outer race sitting below the frame spigot it's register is cut into. This enables the outer edge of the seal to sit recessed into the frame. Unfortunately though its ability to actually seal in these circumstances is a bit 'How's yer father?' and given they are in a pretty hostile environment unless they are well and truly stuffed with grease water ingress is going to be pretty much inevitable.

    The good news is that as long as you do get to them early and pack them chock-a-block, (Yes I know the conventional wisdom on bearing packing.) they will last pretty much forever. The first one I discovered with really badly shagged bearings, (Worse than Vic's!) was a 2008 1200 Sport. At 40,000-ish Km they came out in big ugly chunks! They were replaced and packed well with some sort of marine grade 'Waterproof' (?) grease and the next time I saw them was when the bike came in for a 180,000km overhaul. They were re-packed and went straight back in! This is a bike that is flogged mercilessly, mostly two-up and with lots of luggage.

    Since then I've done several more with similar damage and later checks reveal the success of decent grease and packing. Like most things about Guzzis they are well up to the task and tough as old boots! The problems they have are down to shitty assembly and or neglect.

    Advice given me years ago on grease for swing arms and steering bearings.
    Bob

    Use a good quality waterproof multi-purpose chassis grease. The drawbacks inherent to using wheel bearing grease is that it does not lube at all when packed into bearings that #1.Move quite slowly, #2.Never get heated up by rotation. Wheel bearing grease will not become viscous or 'fluid' until it reaches a much higher temperature than your steering (or swingarm) bearings are ever going to see.
    Chassis grease has a much lower flow temp and will actually lube the bearings, as opposed to having them 'plow through' the much too thick wheel bearing grease.

    Fire away, kids. :)

    Just to update on my Gisa exhaust issues, the Italian company I ordered direct from covered it all under warranty by promptly shipping a brand spanking new GPR Furore (because they said is better and I can see why) that arrived in mere three days! No cat on this one just a sieve cone that's probably meant to create back pressure. The new pipe looks al business and a solid piece of hardware, of almost aeronautical quality. I am really thrilled with their customer service! So now I have renewed interest in getting that sucker, Lucifer, back on it's wheels!

    Then there's all the people that wash them too often! :wink:

    A good reason to have Grease Nipples fitted!

    It's a bit of a sacrilege to talk maps. But I absolutely love mine, I think it has even made me a better person in the last few days!

    I don't wash mine often but have a deep hate for the thick layer of bug guts we collect down here in the warm months, which is pretty much 3/4 of the year. They also attract wasps when stopped. I have removed the windshield few times and took it in the shower!

    When too much crap sticks to it, I use S100 and an electric relatively low pressure power washer, carefully, from a distance. Those nipples scare me. I would not drill my Stelvio!

    At least we'll never descend into the depths of hell that is a chain lube discussion. :D

    These beauties arrived today. Unfortunately I'll have to wait a while to try them out as the Stelvio is in winter hibernation.
    They *feel* and look really good though!

    They look very nice! I need a set that can bring my levers closer, to make it easier for two finger 'covering'.

    I have a scar exactly between my eyes on my nose when my spring tool broke while doing rear shoes on a customers truck.

    Not to sure what to say...thanks?? I go with the rule "just because you can, doesn't mean you should" and conversely, "just because you should, doesn't mean you can"
    On another note, not riding for nearly 4 weeks is killing me. I have replaced all the exhaust gaskets, lubed the crap out of all the pivots (still not necessary), fiddled with just about everything I can without actually riding it. Have a cardiologist appointment Friday, hoping to be cleared to ride, motorcycle and hopefully the bicycle. If not, I don't go back for my next ultra sound until December 22nd.
    Anyone want to talk about doing a BDR next year?:D

    I too have a scar between my eyes, from my wife poking me with her index finger and saying "WTF do you think your doing"... perhaps that's what Dracula is referring to?!

    Dang Mooney I'll ride my Stelvio over and bring the jacket liner as well so you can test it out. I have rarely used it what with living where I do but it is nice when needed. Hope you are doing well, have the doctors release you back into the work force yet?

    I am back to work. Doctors wanted a full 4 weeks out, I wanted one week, we settled on two weeks off with "limited" duty. Which means the letter they provided to HR had a bunch of restrictions. Seriously, how long does it take for the stints to heal???? I'm doing well all an all though. Just anxious to get back to a bit more normal lifestyle.
    As for the liners, I actually have a jacket, pant and glove heated liners. I wanted to terrorize Drac... got to get my feet wet again so to speak!

    Wait. They said you could go to work but not ride?

    Your doctor clearly has some screwed up priorities.
