Actually I was looking for a Panda head or an FZD, found the FZD first so I am going on with that for now, I can buy the Ritmos carb for 75euro so maybe I will to give it a try in the future, so for now I have the FZD 30.24 to play with on the 650ccm , still looking for a good priced manifold and a cam amongst others, I'm actually gathering the pieces for the time being, I'm not going to put all my money in the car at once but it will progress with time. The FZD is jetted for the 650 as it used to be mounted on a 650 engine in a 500 so I will progress with this one, I read lots of AC tuning articles and I search the net daily for good priced items so when I get across some other carbs I get interested, the goal was to find either a Panda head, because I have some Solexes lying around, or the FZD. I wished it was the 32.28 but as it is allready jetted and did'nt cost a fortune I bought the 30.24. Been looking into a sportscam from Poland but this is still pending.
