    His picture is of the initial "incorrect" linkage... they sent him a new one, the correct one. No pics of that. Yet.

    :D

    Hmmm... I guess I'm dumb enough to need captions in order to follow the story. I'll just shut up!



    No offense meant but looks aren't everything and that type of clamp, used in that particular location, looks too much like a possible trip to the emergency ward for me.

    Those clamps are absolutely superior for joining mufflers to headers and so forth but the thought of that threaded shank being so close to my leg, ankle and foot... Well, it gives me the willies just looking at it.

    Still.... Not my bike and YMMV! :lurk

    Here are the 2 linkages. The one with the clevises is the new linkage. Pictures of the new link installed are in the web album at this link but I will post a pic below. You can see the offset is totally different. The lengths are identical however.

    I am not sure that I like the T bolt clamp either. I did plan to trim off the extra bolt length should I keep it on the bike. Overall it is a bit more bulky looking than I wanted. I just don't have any more of the screw band clamps and if I go that route I want them all to match. The T bolt thing was just a test to see if I liked it. It does function well though.

    And on another note...the only real leak I have in the bike is coming out of the transmission shift lever that I replaced. It didn't leak before I changed it. I was warned to be careful, and I thought I was, but for some reson it drips quite regularly since the change.

    The 2 linkages, old and new (new has clevises):

    Here is the new linkage installed, it is perfectly parallel to the frame:

    Here is the drawing I sent to Motocicli Veloci:

    You measured that rod to a hundredth of a degree?

    ...and a hundredth of a millimeter?

    lol...yes and no.
    First I bent the coat hanger to the desired shape (seen in one of my images). Next I do a trick with the computer where I take a photograph of it, load it into a CAD program, scale the photo 1:1, then I just use the software to draw on top of the picture, creating a 3D model of the part. When I make the drawing from the 3D model, the dimensions automatically come out to 2 decimal places. I didn't bother making the extra effort to round the numbers. The manufacturer will apply the appropriate tolerances anyway, which in this case would be simply getting it close enough. Here is an image of what that process looks like...you see the CAD model drawn over the picture of the coat hanger with the digital caliper used for scale reference.

    I used a modified Raask set-up on a track bike and frankly preferred the stock footpegs even for track use. The pieces bolted to the ear that supports the stock passenger pegs and resulted in pegs that were less solid than the original pieces. Was disconcerting to have the footpegs give a little when shifting your weight.

    Stock airhead footpegs don't drag before the heads if you've got any kind of decent suspension on the bike. They're solid and they're not too badly located, imho.

    imho, fwiw, ymmv,
