It seems from loosely reviewing the stats on bikes that the average main jet size for all those with the freak is somewheres around just under 150 or so average. A few are way up there higher and in some cases you throw out the numbers (Dinqua) cause they are so far outside the norm with big bore and amals and any number of other variables.
Those with the snorkle out and no drilled hole versus those who do have the hole is a much closer tolerance of main jet size. either way 130 to 135 seems to be tops with or without the drilled out bottom of the airbox.
Nuthin scientific in all this of course and each bike is different yet close enough to simply tally up numbers and reach an acceptable starting point.
I think if we ran the numbers on pilot jets the average would be 43 depending upon the sample size you take. More seem to have stuck with stock pilots regardless of pipes or airbox mods overall.
Once again no claim to anything or proof of anything cause its esy to skew the numbers.
Its clear to see that if we want to we can tinker with jets and airbox mods till the cows come home if we want to.
It'd be nice to be able to dyno every time you effect a change eh?
But then again we are supposed to ride these from time to time.
