    I would have to admit

    The "trim" on motorcycle seat is very nice, good luck finding some similar "trim" here. The edge guard on the back of the seat might be obtained at an automobile upholstery shop that deals in antiques and vintage cars.

    mmmm... . you'll probably not want to hear this.

    By placing a weld onto the frame bracket at the short end of the reinforcement mending plate, you've inadvertently set up potential stress across the bottom web of the original frame bracket. A crack is likely to emanate along the red line, starting at the outer edge of the web.

    The preferred placement of the weld would have been along the long side of the mending plate (green line), with no weld across the end.

    Or the brace could have been stepped down into thinner sections to help the transition of load from the very stiff brace to the more flexible frame member.

    Yeah they didn't charge me for the whole thing, all is good. I did get a call from them today saying they were bought out by a new owner and that if I wanted the backordered items could be kept on my account and ship when they come in. I realize you're in the midst of a project so time is more imperative, everything I ordered was stuff just to have for future jobs

    Looking at your attached photograph is post # 296, it appears as if the muffler hanger is not parallel to the frame tubes. Is that an optical illusion? If it isn't straight, that will affect the alignment of the exhaust system and that of your foot peg. Hopefully, you addressed those issues before you welded in the gussets, because once those are in place, it's impossible to properly readjust the hangers.

    Those gussets are somewhat similar to the parts that I include in my frame kits but the section that runs down the lower lip of the hanger is superfluous and could be eliminated. The main thing is for the the frame down tube, the cross tube and the bracket, to be tied together using steel plate and a continuous weld.

    The rear sets are available form: http://www.motocicliveloci.it/
    Or
    Omars here in the states: http://www.rearsets.info/bmw_rearsets.html

    The only real issue with them is that you end up loosing about 80% of the effectiveness of the rear brake. If you're a rear brake user, as I am, you'll need to make some changes in your riding style but if you come up with a work-around, I hope you'll share it.

    Thanks for the input, Josh has already mocked the exhaust onto the bike and it is some sort of optical illusion with the photograph I think, very excited to see what the R12 exhaust looks like when all said and done. Thanks everyone for all of yoru input, your comments, your concerns and feedback, much appreciated.

    Sincerely,
    Shane

    Speedo Done

    We received the Speedo back from Palo Alto, the white face is going to go very nicely with the Porsche white race stripe that is going on the bike, as you can see we set the odometer back to 00000. They restore the entire gauge inside and out. Happy Holidays to everyone!

    Thanks, your new BMW comrade.

    Don't know if this anywhere close...probably need to hear from the Germans or people fluent in the language...but google translates "revolutions per minute" to "Umdrehungen pro Minute".

    Love it

    Thanks for the German Translation, that is what I love about these bikes and the Porsche Cars, authentic. My Porsche has an Oel Cap as well. Just another reason why older cars and bikes are so appealing and unique versus modern cars. I would not take a modern BMW motorcycle over a vintage one anyday, there is something about the history and something special about something old being brought back to life for the road.

    Sorry to get philosophical again.

    In my home state of Alabama, that cap would have to spell "Earl".
