hello,
in another thread I have seen a beautiful CB 900 from voxonda. but some members had not been lucky with this bike. therefore I had the idea to bring some photos of my old cb 900 in the meantime.
to my mind, it was not a bad bike. unluckily the bike was much more expensive to race than i.e. a Z 1000. all the race-kawas had been bored up to 1200ccm, had been reliable yet and very, very fast. with an extreme effort I brought my CB 900 to beat the kawas.
the engine was a stock cb 900 case, 1130ccm, bigger valves, racing cams (RSC or Andrews?), carillos, RSC dry sump lubrication, RSC dry sump, close ratio gearbox, Keihin CR 31 or 36er Lectron (does anybody remember, the carbs without any nozzle). this setup was strong enough to break the (new) primary chain within 4 laps on the salzburgring-raceway. therefore a RSC crankshaft (lightened and balanced by Höckle, Germany) with the wider primary chain and primary drive sprocket was implanted. now the engine was really strong and reliable too.
25 - 30 years ago:
Lectron 36 carbs
same bike with race fairings, alu fuel tank and carbon/kevlar rear seat (grid girls looked the same as today
:
frame was done by a friend of mine (hello peter!! thank you for your excellent work):
here with the famous CR 31
all the RSC stuff was brought to Austria by a friend of mine, who travelled to england several times a year. I do not know, where this stuff comes from (Harris, Spondon??), all the engine covers in magnesium, detto oilpumpcasing and sump:
overall weight of the bike ready to go including oil (without fuel): 169kg
some more specs: Dymag Magnesium wheels, Spondon front fork, DeCarbon rear mono shock.
I regret that a have sold the bike of course. last year I met the owner surprisingly. but he is not willing to sell the bike
