    Great thread. Lots of inspiration. That exhaust looks amazing. Would be great to hear how it sounds when you break the bottle on the bow, and turn her over... Wait, that didn't come out right, whatever

    You'll need one BIG bag of popcorn. I'm in Mexico for a while now as I used up all my vacation for this year.

    Damn.
    Well, while it is still fresh in your mind, you didn't happen to grap a measurement of that HPN sump ring- how deep it is at the front and at the back?
    So um... how's that Ducati coming along?:D

    I say since AW is out of the country, that some of us get together and finish this thread ......bike , for him. It'll be our little secret. I'm sure there's a "Lone Wolf" in Washington State that could do it.....

    Unfortunately, no, I didn't measure it. I bet you could get pretty close scaling it off this photo. You know the length of the oil pan so some photoshop measuring and calculating could probably get you within a few mm.

    Cheers, that did the trick. I used a silicon sump gasket I've got for the reference, blew up the image and just measured off the screen with a tape measure.
    My calculations came out at 31mm (rounded up) at the back and 51mm (rounded down) at the front- which assuming a bit of error is probably more like 30mm at back and 50mm at front.
    Which is a good thing for me, because 50mm at the front is exactly what I need for the sump bottom bash plate thing to clear the bottom of the headers at their lowest point.
    (my stainless headers are home made by someone, and sit a bit lower than stock, and I wold like to make a bash plate to bolt onto a sump ring like you've got that extends out the sides and will cover them as well).

    Now the tricky part...
    contacting HPN.
    Wish me luck, I'm going in.:D

    Well, if you're thinking of using the HPN sump ring for that idea, you've got a not-so-small problem. The oil drain plug is on the left side right next to the header. There's another threaded hole, but it's on the front, so it can't be used as a drain plug. It's meant for an oil temp sensor. Both are visible here.

    Thanks, that is a little annoying.
    One way around it might be to have a hole in the wider bash plate where the drain plug is for a spanner to access the plug- on top of this hole there would be a half funnel welded on and facing the plug so that when the plug comes out the stream of oil gets directed down and out the hole...:D
    Way complicated of course. Potentially a bit messy.
    My problem is I want to avoid bashing my headers in with flying rocks (like has happened on my R90) and along with having the bash plate as the lowest point I would like it to cover the bottom and front of the headers.
    Being a custom made exhaust system (at least until a staintune muffler from a different bike was bolted on the end of it) I can't exactly just buy a new header if I damage one badly. I could just plan on cutting and welding any bad dents, but I'd rather avoid them first with a bash plate if at all possible.

    None of the other sump rings I've been able to find measurements for come close to giving me the depth I need at the front.
    I did just check the price of the HPN sump though... so I'll be chewing on this for a little while.:D

    Sorry to clog up your thread.

    P.S. that angle and that image you just posted is er... kinda erotic... :sweeti:D

    Yeah, for some reason they charged me less for it. Their price list says 340EU which includes 19% VAT that you don't need to pay. Still they only billed me 251.68EU for it on my invoice. Give them a call and ask Klaus how much they are. Don't bother with email.

    AW,

    Maybe I missed it, but where did you get the triple clamps to fit the WP forks to the ST frame?

    Thanks,
    Jeremy

    They came from HPMguy from his first group buy of these. He's got a second run of them going now it looks like:

    My only comment on them is that the stem is a little too thick where the bearings fit. They needed some hot/cold to get them on. Getting them off the first time is going to be a bitch. Otherwise they are REALLY nicely made.

    Re : Next came the rear brake. Since the swingarm got lengthened 100mm, HPN provides a longer replacement for the brake actuating rod. Instead of a solid rod they provide a flexible steel cable with a plastic sheath over it. Pretty slick actually.


    Hi Spencer

    Just got into your rebuild thread. Great job. Make me feel the itch to finish my beemer projects. If i may give you an advice, you need to turn the back brake lever or you are going to destroy it the first time you hit a decent rock. To do so you need remove the brake cam and make it symmetrical so that it can work turned it up side down. The HPN bikes have the same setup. Good job...the germans will say "prima!"

    Hi Airhead, the bikes looking great,nice thread to follow as you know I went through the same slow process of doing bits at a time even when I got her all finished it took another month to get the suspension all set up right and the motor running perfect with the different exhausts and all - so your getting closer but still a way to go but hang in there its worth it in the end.

    Your set up was good, but I'm going with soft luggage this time. What are you running on your new bike?

    There is now an electrical plan. Rather than reinstall my stock harness which is old, cruddy, muddy, brittle, and half irrelevant, I'll be installing a motogadget m-unit and getting rid of a LOT of crap. Here's what things looked like after south america when I tore the bike down:

    [​IMG]

    The thought of replacing all that crap with this is enticing:

    Plus none of the handlebar switches carry any load anymore, only enough to switch a transistor so I can go to a single 8 conductor signal wire from under the tank to handlebar controls. All switches will get replaced with push buttons from highway dirtbikes like these:

    Very nice, as soon as I saw the harness on my bike, I ripped it out, and threw it away.
    Love those handlebar switches!
