79 kz1000 shaft drive carby info

hi guys im a newby to this site and to the 79 kz1000 shaft drive. i have taken on the project of rebuilding and getting the father inlaws bike running for him...ive read alot of the threads about how to tune and and what jetts to run in these carbys but still have not got a definative answer so can anyone give me the right info on setting up these carbs and jett settings.. the bike has some cheap individual air filters and a 4-1 exhaust system.. any info would be greatly appreciated

Check valve clearance,compression test,check ignition/spark.
Then you can start buying jets.
The ST came with 110s,try 1 or 2 up(112.5 - 115),raise the needle 1 for starters.

Cheers I've done all the clearances and timing just after more specific carby settings and mods

Anyone at all??

Are stock carbs currently fitted? And what size jets (as they may have already been changed)?

kawasaki.com shows for KZ1000-E1 shaft carbs: 115R main jet and 15 pilot jet.

Would restore the carbs to as-new condition and test run before changing either jet or the needle clip position.

The rule of thumb seems to be -- with pods and 4>1, typically increase stock main jets one size, maybe 2;
and might or might not help to increase the stock pilot jet to one size larger.

Position of the jet needle inside the needle jet governs air-fuel mixture during mid-range throttle operation.
A lower clip position raises the needle to a relatively higher position in the needle jet, which affords a richer mixture.

The main jet governs air-fuel mixture at wide open throttle.
Needle clip position has very little, if any, effect on the air-fuel mixture at wide open throttle.

Good Fortune!

Clymers manual shows 110s and all 3 of the STs I have owned including the current unit came with 110s.
Current bike w/1105,high lift cams,police exhaust,main section of the stock air box w/K&N runs quite well with 110s and the needle raised one notch in the old 28s.

As listed by Power Sports Plus: 92063-1038 MAIN JET,#110R

Note -- the lone pilot jet listed is #A15 (same at kawasaki.com).

Good Fortune!

Thanx guys.. That's a big help.. Do u know if this model came with a all the smog gear on them and if so is it better to blank it off or leave it on??

Kawsaki.com shows the clean air system on 1979 KZ1000-E1 shaft.

Removal doesn't impair performance, and reduces risks of air leaks.




Good Fortune!
