The P2 needle jets were great, and have the needle clips on position 3, the center. I had been compensating the rich midrange with a leaner idle mixture, have now gone back to 1.75 turns open on a 40 idle jet, this needs small amounts of choke to start on warm day, cold engine, and has great throttle response from a standing start or off throttle, much better than I was able to get with the stock VM30s. Also is better with #40 choke/ start jets, I don't have to be as careful with the choke now. I have 250 main jets and these now seem a touch lean so will try going back to the 260. I think it really needs the exhaust port timing increasing, would help the top end power and give a longer blowdown time for the chambers to work better.
