    XJ900 Cafe Racer...
    Build by Greg Hageman based upon a design brief that asked, "If Yamaha had evolved the xj line more towards a naked, cafe racer motif, what might the xj900 SECA look like circa 1999?"

    where did you hide the battery?
    1. Mike Martens
      It is in the tail cowl... Lithium Ion job. Works great, smaller, saved a few pounds too.

    Can you explain the carb set up on this bike. Those aren't stock to that bike, are they? They look like flat slide carbs, off of what? How do you like them, as far as, response and maintenance?
    1. Mike Martens
      You are correct; mikuni flat slides that had been set up for the fj1100. Had to have some extensions machined so bowls would clear the alternator. Carbs were dyno tuned and we were able to go up on the main jet a little, and had to lean it out at idle some. They sure make power at the top half of the rev range, and they fire right up no problem.

    I have a photo of this from Barber a few years back, I rode my red/white 81 seca over with some friends from Atlanta. I prefer stock to most customs but this is very tastefully done. awesome build.

    Did you completely disassemble it to paint it? Is the engine done in one coat? No primer, or finish?
    1. Mike Martens
      While Greg Hageman did the build and the design, I had Eric at Flying Tiger Motors in St Louis MO dress the motor... and yes, he took it out of the frame and disassembled quite a bit to get to everything. It did a great job.

    Cant really tell, but did you get a after market tail light? or did you push the stock tail light back into the housing?
    1. Mike Martens
      It is an aftermarket LED job with two round lights that are both brake and turn signals. It all sits behind some black mesh and, when the key is off, is pretty clean, but with the key on the LEDS shine through brightly.

      That is the crankcase breather. No sense in hiding it now that she is all naked.

    ..those beautiful forks, how or where did they come to be?
    1. Mike Martens
      Forks are 43mm units from an FZR1000.

      Was that a direct bolt on, or was some tinkering required to get it to fit the frame?
