I'm trying to figure out what you mean by needle jets. Do you mean the main nozzle? There are 2A and 3A nozzles with 2A giving a richer shot of fuel off idle when you hit the throttle. Also stock pilot jet for the mikuni butterfly in the Phazer is #95. I never heard of a #56 or #50 pilot jet for a Phazer but that doesn't mean they don't exist. I would start with 136.3 main jets and go with #95 pilot jets as well as the 3A main nozzle for operation at 8000 feet. One thing to check is that the rubber plugs are in the proper place inside the float bowl chamber. One should be over the pilot jet and the other over the center hole. The third hole does not have one on it. It's also a good idea to change the primary nozzles to the ones with the thru hole (part no. 80L 14489-00-00) if you are going to run aftermarket pipes. Also check out this conversation on Snowest.
