    They've never taken me more than five minutes. It is simple if you know a few tricks. I just knock them out with a brake spoon. If, for some reason that doesn't work, get a washer that has the same OD as the race, grind two flats on it so it will pass through the ID of the race, set it flat on top of the race, put a big bolt through the washer from inside the steering head, place a drift in the center of the bolt and hit it with the biggest hammer you can find.

    dude, I tried it all

    dry ice worked on the top one, cool trick that

    I just mangled the bottom one and had to clean up the frame with a dremel

    I regret taking them out because they were in oerfect shape but with the fram going to a powdercoater I figured I needed to fully strip it
    the homebrew slidehammer sounds like it would have worked fine, wish I had tried that

    more air = less torque?

    what am I missing? of course me missing something obvious is par for the course

    I am going to keep the motor mostly stock, no 336 or hi comps

    the cafe treatment will be primarily cosmetic, you are right there is just not a lot of speed to wrung from that motor and I like the power it makes well enough.

    I just want it to breath mo betta and maybe put some dells on it, maybe not. Throttle response is lame on this bike

    I will move the MC up on hte bars - I'll use the regular guages because they will be under the fairing anyway

    Ikons are a plan

    Jtwind's bike is pretty close to what I have in my minds eye, but I want to lightent he look with aftermarket signals, bobbed fenders, no side refelectors, wrap the headers and out on some dunstall knockoffs (might even consider some supertrapp shorties)

    my motor is a 1980 with the boyer can so I'll upgrade the coils to some dynas

    Probably get a whole new harness for the bike, not crazy about teh idea of using a 25 year old harness from a bike that sat for about 8 to 10 of those years

    Probably do the flywheel

    as an act of cafe blasphemy I'll probably keep the luggage racks but I'll black them out too

    I want an good looking old school rider

    Mutt, I'm doin' the same thing w/ my R80RT. When I got it, the fairing had already gone into the trash. I ordered some S type bars from Eurotech yesterday. They make two widths in the S bars, one for early(drum) bikes and one for Later(disc) models. I had the same thing happen w/ the steering head bearings(almost). They were all but seized up when I got the bike and I could not figure out how to get those races out so I left them in and just replaced the bearings. Guess I dodged the bullet on that one. I also ordered some Dunstall type mufflers for it. I saw them on a /5 and they looked bitchin'. I put some fork boots on the front end while a I had it apart and got the whole thing back together w/o reinstall the signals.......... Fuck it! I'll take some pics of the new lower bars when I get them on this weekend.

    This is what it looked like when I got it:

    Read Snowbum's web-site if you're interested in details on pod filters versus stock airbox.

    For improved throttle response, consider a Mikuni conversion kit from Stan at Rocky Point Cycles. Nice guy, and he rides a /5 and a Commando.

    I've built several BMW cafe bikes - mostly on /5's, but the R100 is easy to modify into a proper cafe-style. Feel free contact me about sources on parts - I've got lots of them.

    I've also got a large selection of period aftermarket tanks for BMW cafe bikes - can send pics if you'd like.

    I have a 74 90/6 that is ripped apart for mods so no pics right now-sorry!
    my mods are a Mac 2 into 1 pipe- better sound and I noticed an increase in revability and power, BMW 1/4 fairing, S bars, upgraded front rotor and stainless line, and braced swingarm. Haven't seen anyone with the brace in the pics but it made the bike wallow less in the sweepers. I would add the frame braces and a front fork brace- makes a big difference in the handling.
    I'm going the other way with my /6- a solo seat-old harly springer and wide bars, maybe even floorboards. I may put the 1/4 fairing back on, don't know. It's gonna be my wierd cruiser- got enough bikes that go fast

    How about some info. on those chrome signals? Where did you get them? Do they fit right onto our airheads? /6s? And how about that Corbin seat? Any mods needed for that? Thanks. Great bike.

    The alloy turn signals are made by K&B? Lot's of sources. The rears are monted in holes in the subframe, the fronts on shortened stock mounts.
    The Corbin drops right on, as the subframe is from a SWB /5. If you don't use longer shocks it will handle "funny".
    When you order from Corbin, you can get the seat anyway you want, but you must be insistent and get transfered from the regular order folks. I wanted no pleats or piping and the online and regular customer service people said it was "mandatory". I told them it was not "mandatory" that I buy the seat...no pleats, no piping, thank you.
    BTW, This thing can be changed back to stock appearance in about twenty minutes.

I need to go thru it and redo all motor seals gaskets and rubber, and in short strip all apart and rebuild for kicks... re looking at bikes for ideas
