    Ooops you got me... :D.

    The old airhead bearing has the metal cage.

    Your bearing has a plastic cage, and it is sealed on one side but does not have the additional dust seal,

    There is a third bearing for the R100GS which is identical but it has a beefed up raised 3mm section outside the race for the additional dust seal.

    I used parts from all three bearings, so I have a indestructible bearing with a outer dust seal. :lol3

    There are some advantages, but I tend to over think things. I'm sure the stock bearing will be fine as long as it's kept tight. :beer

    Well, I contacted my dealer today and they have the bearings in stock. The are 47.20 for each. Going to go ahead and replace those.

    On a different note I don’t know if I’ll keep this bike or sell it in the spring. I like projects and have been hunting for one of these as they are supposed to be super smooth. I already have a 1150gs for long distance touring or gravel roads. I’m pretty certain I want to turn this into a commuter/around town bike. Something I can run to Seattle on and get around town easily sounds fun. I’m pretty certain I’m going to make it mostly stock.

    Any must do mods that anyone knows about? Might try and convert over to regular bars as the bars on it are ugly but I want to wait till I get a ride or two on her. I also really want a windscreen, anybody know a good place to find one. I also want to find a tach to throw on. Just need to find a stock one, my windshield mounts that I have have the mount on there if I understand correctly. Anyways enough rambling tonight, hopefully tomorrow I’ll get to Throw the clutch in. Once again thanks for your help guys.

    Have you thought about changing the cam chain tensioner on the left cylinder to the one from a 1200? It will fix the rattle on start up. a quick internet search will give you the details.

    Was able to get some time in the shop today. Started off with reassembling the clutch.

    Then using the tool lined everything up inserted in the main shaft.

    Then torqued everything down and the clutch is back together.

    After this was done I have it a quick oil change as the bearings were cooling off.

    Next I put In the new fuel pressure regulator. The old one was busted somehow.

    Got the lines installed on the new to me fuel regulator.

    Anybody know of a good fuel filter to put on these? Does it really need it?

    By this point the bearings I figured had cooled off enough in the freezer so I set about driving the old bearings out.

    Bearings popped right out. Where the bearing sits appears to be in good shape. So I got out the heat gun and started to install the new bearings

    Unfortunately I forgot to get a picture of the new bearings installed. But new bearings are in and now on to wait for the transmission To come back, maybe next week. Once that’s on, swing arm is on, I’m going to try and see if it will run.

    Going to start next on the wiring at the front light as the po has torn all of this apart and wired in his own universal tach and speedo. Going to take it back to stock.

    Well started on the dash as I’m waiting on the transmission. Finally ripped the old speedo off as the po had put a custom speedo on. Trying to figure out how this all goes back together was fun but it needs some paint and some fasteners. I think I got it figured out but please point out any mistakes. Hoping to pick up a new stock screen soon. I did find out that parabellum makes an screen.

    I installed the covers and some aftermarket turn signals. I got lucky as the bike has a signal minder on it. I’ll try and get some better pics tomorrow before I head to Canada for the weekend.

    Great stuff, thanks. The R's are mostly underrated…..yet they are fantastic bikes and handle as good or better than a GS. Such a bargain.

    Those pictures help more than all the time I spent fiddling with it. I did manage a couple of pictures today.

    Yeah I’ve had some time lately, but fortunately I have been cleared to go back to work. I tore my Achilles and have been out for about 1.5 moths. Once back at work then it will slow for sure, well maybe. I also am starting diet and exercise as that will help my foot out as much

    Got some more time out there today! Also got in the new valve covers and guards so time for a valve check and new covers to go on.
    New used covers

    Old ones....

    I guess the po dropped the bike while messing around with emergency stops. This was the main damage but both sides were beat so I got lucky and found a really clean used set.
    Take old ones off

    Then button it all up.

    Looking good!!!!
    Does anybody know of a socket that will fit down and in to get the spark plug out? My regular and spark plug sockets are to fat to fit.

    Tranny will be done tomorrow but installing chimney again to get the stove ready for winter. Hopefully by end on Sunday I’ll get to hear it run. That’s the dream anyways.

    That tool kit socket doesn't work? If not, you will have to turn down a standard spark plug socket, or get a thin wall deep socket.
