I think the extra set of ninja 600 carbs I have will work perfectly!!! With a custom ram air box !! Just a thought for the future probably very near since I just reminded myself I have those collecting dust somewhere. No more computer!! Yes!! Right??

Did those carbs have vacuum ports so you could connect a set of manometers? I used to ride a '79 Yamaha 750 triple (about 80 hp); when the carbs were properly synched, it made a huge difference. I never did find a bike shop mechanic who would bother to do a really good job of synchronizing, so I did it myself. When done right, the carbs would stay in synch for quite a while. This was on an air-cooled engine which lacks the thermal stability of the water cooled G10.
I drove a '65 Austin Healey Sprite, back in HS. It had dual SU carbs. I had one of those little venturi manometer doo-dad gauges, that I used to try to sync mine with. Never had the best results, though. IIRC, you were supposed to put some kind of ultra-thin, unobtanium, mineral oil in the hydraulic damper reservoir in the top, to keep the piston slide from acting too jittery.

Come to think of it, you were also supposed to put similar oil in these cast iron, lever arm actuated, box type shock absorbers. And to do it, you either had to unbolt them from the frame rails, and turn them upside down, or turn the car upside down. It's no fu'kn wonder the Limey's lost the Colonies.

I'm wondering if some old side-draft carbs from an AH or Triumph, might not be better suited for retrofitting a G10 engine with? At least they were designed to work with water-cooled car engines.
I had a 1961 Austin Healy Bug-eye Sprite with the SU carbs. I put in a rather huge cam in a later model 1275 cc engine. SU carbs hate lumpy cams. They need a minimum amount of vacuum to idle properly. As I recall, Mr. Murf is running is running a fairly radical cam.
That's funny; mine had a late model 1275cc engine in it, too. That must have been a popular "upgrade".
