Here we go again...

Husa, Of course, you are the master when researching and producing photos of stuff, but for people like myself who have been away from the scene for years and years, the photos can be a little confusing when not labelled! - luckily I did happen to know about the Ducati arrangement (which I assume these pics are of), but would you label them? ie. when you can.

Thanks, Will.

Fair enough, the last ones BMW

Funny thing that, since I have to go up there and pick up a CBR frame if he's still got it. So the motors might just end up back at his to be built after all.

Sorry to question this particular one but I don't think it's BMW - Ducati I believe! (one of the very few I actually do know), but thanks anyway.

last one as in last picture in series.
The others were all Ducati though

With the F800GS, rather than utilize a pair of counter-balanced shafts, BMW employs what’s called a balancing connecting rod. This helps keep the engine compact and allows for use of a semi-dry oil sump. The method by which this balancing rod works to counter vibration gets a little technical and any attempt by me to explain its operation would have you snoozing at the keyboard in no time (it’s akin to the system used by Ducati in its rare single-cylinder Supermono –Ed.). Put simply, the balancing connecting rod is set at 180 degrees from the crank pins, thereby “the mass forces resulting from the swinging movement combat, in every crankshaft position, the oscillating mass forces from the crank drive (piston and con-rod proportion).” Dry stuff, but it works well.

Ah, missed that - ok, sorry

That principle was first invented by Doug Hele (who was the designer at Triumph) about 25 years before Ducati used it! - I remember that, but didn't pay much attention at the time!

How we doing?

[Drew]

No progress since the new front end went in it. Other than stripping the frame and cutting off anything I didn't think needed to be there.

I'm toying with a really dumb idea, based on a fucked motor that's in my shed.

A CBR600 motor that's fucked, and a GL145 hybrid. Bottom end of the GL, and a quarter of a CBR barrels, slug, and head.

Is it possible to the minds of others? Is it a case of taking to things with a band saw, sealing the water and oil galleries exposed, getting it to bolt on, and cranking up my one off 150cc twin cam, four valve, water cooled, 12000rpm beast?

Depends on what year the 600 is if it's worth while or not. Not impossible though and would be awesome!!

[ducatilover]

Would be plausible with an f2 onwards motor? I think f1 motors had a central cam chain, whereas later ones were hangin' out the side.
But the deck height may be way the fuck too low too

Cam chain hangs out the wrong side though. Need to use F1 and put a case around the chain.

Cam is laterally retained where it will remain after the head gets chopped up and everything.

Guy did one on salt flat racer based on a postie and poweroll did a 150 on a cr85 can't show you PC is dead so yes of course a vt250 on a Honda single has been done as well

Best be would be to use the stock barrel and get a modern 600 head where the chamchain etc is on the right side and put that on the stock barrel (with a new piston)

a 89 600 head will be pretty rubbish even if it a 4V
