Z1,Z9,Z1000.AIR CORRECTOR JETS. Last few sets.. Price drop...

#1 PostAuthor: zed1015 » Wed Jun 20, 2018 3:16 pm

I have a very limited amount of air correction jets going spare.
For those not in the know these almost mythical and long out of production jets were originally designed and dyno developed by the legendary Leon Moss and marketed under the LEDAR brand.
These are essential when running your Mikuni VM26 - VM28 equipped Z1/Z900/Z1000 and Suzuki GS750/850/1000 without a stock airbox to correctly eliminate the low speed lean fueling condition flat spot that results.
Also improves running over the entire range with an average increase of two to six horsepower overall and provides a much needed level of added adjustability to the stock VM that was only previously available on the smoothbore versions.
Fitting these jets pinpoints the low speed fueling problem created by running open carbs or high flow filters and does not detrimentally richen the overall fueling the same as lifting the needles does which can result in up to 25% power loss and raised fuel consumption..
You will need to internally thread the air bleed in the mouth of each carb 8mm deep with an m5 x 0.8 tap (not included ) .
The air bleed orifice is already the correct tapping size so no drilling required.
See the attached pics for images of the jets and the forth pic for fitting reference with the correct position of the air bleeds highlighted and jets installed.
These are £35.00 posted to UK for a set of four jets ( second pic )
Thanks.

Hi , Mark. Don't know if they used the same size drilling for the CV's but the instruction leaflet says for Mikuni CV's also and that they are not handed and go in the 4 o'clock position on all carbs
These are 0.6mm which I bet are close but any reduction over standard is a step in the right direction..
If unsure you would be better off replacing the whole lot as I only have full sets anyway.

Yes! Any Z9/1000 running VM 26/28mm round slide carbs without the airbox.
They also work with the Suzuki GS's with VM's and I also have them in my ex 1000 katana 32mm smoothbores.
