    No!:D
    Its got super-bike acceleration but I had hoped it would do more to the gallon with the carbs being newer technology. If I hammer it to the red line in first and slam the throttle shut its as though the back wheel has ABS and I get a big dotted line behind:D I've only just got them set up right and the first tank of petrol went in 118miles. That's 31mpg(imperial not American):huh
    If I can't get it to do 40+mpg then they will be going. Good thing is they don't pee petrol all over my feet from the float valves:D

    The stock Mikunis off of Monsters leave a lot to be desired. I had a M900 for 6 1/2 years. For about the last 4 of those, it had Kehin FCR flatslides.

    Coincidentally, the FCRs improved the mpg on the M900 from about 41 mpg to just over 45 mpg. Highway or around town the same.

    If i were going that route on my R80, I would be looking for some Kehin FCR split singles in 39mm. (I had 41mm on the Duc.)

    Edit: I looked back at your vent hose arrangement - can't see for sure, but each carb need to have that hose routed in to a dead air space somewhere near the carbs. They are very sensitive to air currents and fluctuations at speed, which in turn may affect mileage and/or rideability. They shouldn't be plugged directly to each other (which it almost looks like) because of the strong internal pulses affecting the carbs with every intake stroke. They need non-turbulent free air to supply to one side of the diaphram.

    Hi!

    The motorne cover is made of fibre glass and doesn't fit too well. The aluminium version doesn't seem to be available. We did it ourselves as cast aluminium.
    The seat is not a Ducati seat, this one is hand made, wider and fits perfectly to the BMW rear frame.

    Greetings, Rudi

    Did the K front end just bolt on - that's what I've been told!! And I knew theoretically that the oilhead brakes are a bolt on too - now I know for real!!

    My bike will be a Frankenbeemer too I think - already have R65 frame and motor, R75/5 gearbox, K1100LT rear wheel. Will have K75S forks, brakes and front wheel, with R11** front caliper.

    Still up in the air about the tank - you've done a great job there - well done!

    Ta!
    I used K100 yokes because I knew I wanted clipons. The 75's have a built in riser affair. The forks are 75's. I changed the stem but other people have told me I didn't need to:eek1 I did it on the garage floor with a blow lamp and a lump hammer so it cost nothing and was easy enough:D
    I don't think the steering lock would have worked if I'd used the K stem.

    Great looking bike. Personaly and FWIW I wouldnt attempt a carb swap with out the aid of an air/fuel gauge. Lots of guys have put FCR-MX flatslides (the standard latest generation 250cc + 450cc MX 4 stroke...) on the DR650 and were getting brutal mileage except the bike was running good. With proper jetting via A/F guage mileage increased dramaticaly and the bikes run even better. I have the NGK AFX Powerdex A/F guage. $300 including extra extended SS sensor bungs shipped across a continent. Just sayin'

    I don't know where he's from, but his name is Len. He and another guy are putting it together. Way cool double tank. Man- I love that bike.

    Thats a /2 frame, and the valve covers are of the plain-jane variety, i.e. an R50 or R60, not the "hot" R69.... so, the color is great, the tanks and the rig are cool, but... speed....??

    Style points galore....:clap Love that front brake scoop!

    :huh

    I can't remember what work they're doing, but it's not totally stock inside. I think they're shooting for 120mph.

    45mpg today. Been all this time to use a tank full of petrol thanks to the good old British weather. Could be worse we were under 4' of water this time last year.:D

    G'day Folks,

    Here's a picture of mine. It's a 1983 BMW R100RS. It has a Ducati SS fairing, Darmah fairing mount, caferace.com seat, Raask reasets, stainless pipes and Tingate clip ons. It's not a show bike and gets ridden a lot. I love it.

    I've never managed to get the rear disk working properly with the rearsets. I had to bleed the line with a pump but the lever ratio seems wrong as the brake doesn't bite hard. Any ideas out there?

    Cheers for now,

    Nestor.
