8 bikes there and two of them aren't even BMW's
Seat had to be cut all around the front to fit the tank. I got a fram and monoshocked it from a newer bike who's engine I used as well. The wheels are R100R and had to be machined to fit. The front end is K series and oilhead brakes.

No!
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 I've only just got them set up right and the first tank of petrol went in 118miles. That's 31mpg(imperial not American)
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

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.

I think the rear seat cowl is a Ducati replica?
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 I did it on the garage floor with a blow lamp and a lump hammer so it cost nothing and was easy enough
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'
