all the microfich pictures that I have seen at bikebandit, kawasaki.com and others show that the slow jet is under that plug and its a n424-25. but as mentioned its 15mm long with 2 side holes and mine is 19mm with 3 side holes.
I do have pods but have custom made 4 into 2 pipes with 4" baffles.I can get the #140 mains but no action on the #42 pilots.
I'am so close to finishing this is driving me nuckin futs:blink:
can I get a really small drill bit and oversize them?? if so what size??
I'm getting desperate. my bike runs like poop with the carbs as is so leaving them as is ain't an option..
anyone got a set of mikuni bs34 they wanna trade for..

Easy to get and if using something smaller here then you will need bigger.

the drill is a last resort but I really am getting desperate.. like I said above the top end is ok its winding down to an idle that takes way too long. thats why the obsession with the low speed idle..
you are the first one to mention the secondary.and the book dosen't mention them.sudco has the mains . another thing is that the specs call for the pilot th be a #37 and its a #35. this carb has been around so I'm noteven sure that its is from a kawa.. but keihin is keihin..
so you think that the secondarys would affect the ammount of time it takes for the idle to come back to normal??

...will run as is over 3k for almost a full minute before it settled back down to a respectable idle.when running there seems to be NO problem with the topend (runs like a raped ape:woohoo: )its just the slow idle.
Random thought -- is there an ignition timing advancer unit that could be hanging in the advanced position so as to delay returning to lower idle rpm?
Another -- possible leak allowing intrusion of outside air being sucked into fuel mixture and causing unstable idle. Usual suspects are old cracked carb holders, loose clamps, hard vacuum caps, cracked vacuum line, etc. Could check by spraying WD40 or propane around suspected areas with engine running, and notice any difference in rpm or smoke from exhaust indicating WD40 or propane neing sucked in from the outside.
And one more -- throttle cable connection and associated carb fittings might be too tight without sufficient slack to readily allow immediate full closure upon releasing throttle, or maybe throttle cables just need lubrication.
Good Luck!

if no action by this weekend I'm gonna put everything back together and fire it up and do that leak test thing.I have a float valve that was stickin and thinking about that and what Patton said I should check some things..
also jmargrav does your books tell where the needle valve should be,,ie. which notch . is there a setting for racing since the pods allow more air like a race carb would do.my $80.00 service manual only mentions makuni carbs..
I checked wiredgeorges site and found out that he was sick and outta the game for a week. he says he's better but playing catch up. been to texas and it gets major hot there..
I appreciate all the help.
