20/120 9 air and the sudco mikuni manual says the standard
jetting they sold them with for a kz1000 is 25/120 9 air....
any input?.....if i read the sudco book right, the pilot mixture screws are on the side.....should be a lot easier to tinker with than the other vm series on the bottom....

This is as much as I know about the jetting. It will make a difference with different setups and engine condition.

If the setup is for what you have listed then maybe the pilot jet could be good 20-25 but the main you will find that 125 should be good has to be bigger than 120. I am running lean with my setup but I am going to put different carbs on over the winter so I will just ride a few hundred more miles. That part makes a good difference when the carbs are tuned and jetted correctly for the setup. The carbs will need to be synced etc.

sax,
thanks for the input...these carbs should be here mon/tues
and i will give them the once over when they get here...i think my andrews 2x(mild street cam) might be the diff on the main.....360 vs 410....but then again....i have a suspicion that i will have to bump up main to 125....i guess a little carb install/re-install will be coming up.....thanks again....

Get them dialed in and they should make a big difference. I have a set wth butched pilots that I miss. Talk about a letdown going from the smoothbores to the regular 28's. I'm jealous now, anyone have parts for the smoothies send me a PM.
