Every bike will be different, and it depends on so many factors.
I have bought a real time wide band fuel air meter to take the guess work out of it.
With the standard 276s on my Rap I am down to 140 main jets and the mixture is still rich.
I have checked several Vins and they are all way to rich.
And yes I do ride the bike hard and have done approx 1500 miles with those main jets in, that included thrashing around the IOM for a week.
The only way to do the job is either buy a meter or pay for dyno time.
Don't be tempted to buy other peoples set ups (I have heard of some people selling there results on to try an cover some of the cost) because as above every bike will be slightly different.
Remember most of the advice in the books is old now and the octane rating has changed, this will have an effect.
