Paul, This is very interesting ... your springs being 8.5 inches, (I wonder where those came from ??). Stock springs are only 7 inches long free length and the springs that are used in the Dynojet stage 1 and 7 kits, (DSP044), are 4 1/2 inches long. This would be even more interesting if infact the stock springs are different in 1FK00,01,02 carbs, (I have '02 carbs), because I always thought they were identical. The main jets you list of course aren't stock ... I assume they are Dynojet jets which would make them very close to the original stock Mikunis ... I can't imagine what happened to the holes in the end of the slide ... If someone tried to emulate a Dynojet kit ... the hole closest to the outside edge of the slide would have been the one that would be drilled ... w/ a #19 drill ... .166 inches / 4.2164 mm .... Actually ... if you use the #19 drill ... and drill straight, (using a drill press etc), the hole will be right at the inside edge of the slide. (any larger would infact cut into the inside slide wall). At any rate ... it makes little sense why anyone would not make these holes equal ... without regard to the size they were shooting for ... (this is the vacuum port for the slide .. when installed the hole is at the bottom of the carb in the venturi and low pressure here is what lifts the slide ... the only other pressure relief for the inside chamber of the slide is through a hole in the metal end cap that vents to a reference air port below the throttle plate ... making the hole bigger in the end of the slide is supposed to make the slide more responsive .... if anyone actually drilled any holes near the needle it would have no effect as the needle chamber is sealed with the o-ringed plastic cap screw). The primary and secondary pilot air jet sizes 90/170 that you found are stock for non-California US carbs, (on California bikes .. the primary is a 100). campbell > ----- Original Message ----- > From: "Paul Ries" <[EMAIL PROTECTED]> > Subject: Re: Carbs > > Eric, > > I took apart the carb assembly today.
