RG500 Jetting

Well I have abandoned getting air filters for the 500, just can't get the jets right! I did look at trying to make some velocity stacks for 58mm external diameter carbs but nothin was available that was very short - due to lack of clearance with the fairings. So I am back to trying to setup the carbs better on the 500. Basically the symptom is : Good idle and pickup off idle As soon as you get mid range power dissapears (about mid throttle) and then you need to ease is above 8k rpm at which point it makes great power to the red line. I thought I was running too rich in the mid range so I purchased some needle jets p-4 and p-8 as apposed to the q-2 needle jets that are in there.

After changing the needle jets I can come to the conclusion I must have been running lean as the bike gets better with a richer setup. I am now running 240 main jets and P-8 needle jets and I will probably try going up to 250s just to see. On the other hand did the 120k kms service on the Daytona, all fluids except fork, sparkplugs, plus valves and throttle body synchro. All is well the valves were all in specification.
