The flood of not very atomized fuel can't be good, it is supposed to help the engine off idle, then the rest of the circuits take over. Better, constant flow and no more. A richer bike comes off idle slower, sometimes bogging but has good strong top and higher rev. Corrected it hits sooner, cleaner and pu;;s clean to the top. Stock the crf 05 and 06 are real fat, aren't all the 4t carbs about the same? The more volume sales pitch I find offensive, the o-ring on the adjuster arm good, the shorter diaphragm: if its purpose is to chug more fuel not good,stronger spray might be interesting. The needles being multi-tapered sounds good, and if anyone can tell me what a #30 leak jet could charge, maybe a car?
