The carb on the first pic is a keihin 28 or bigger?
Why did you mount the kart carb on the second picture with a manifold like that? With a hand made manifold you could mount the carb a lot closer to the reedvalve.
I'm loving it !!! +ralf+ do you have any information about the kart carb?
I would like to know how many mm the hole is and what brand it is? and how the performances are, better than the keihin or not?
Very nice! But why these huge radiator? The work on the engine looks interesseting, it seems to be the usual way in italy. I saw similary intakes on the scooter-weekend last year. Which valves do you use? No Problems with wheely-starting?
