Keihin main jet length question and interesting article (PDF)
The attached article has some interesting claims that there is a significant difference between the long Keihin and short Keihin main jets. I always thought it did not make a difference as long as they could fit without hitting the bottom of the bowl and I have used both styles in the same machine. The chart on page 2 is very interesting, it claims that there is a large enough difference to offset jet size (#125 long jet = #105 short jet size) Opinions?

EDIT: I am a moron, this is for Mikuni jets, may not hold true for Keihin.
sorry, still a good read though.
