How to adjust timing on zzr 400kawasaki shabs

sounds like a fouled plug or a timing adjustment take out the plugs and look for oil on the plug. if there is oil on the plug clean with degreaser and try it out. If you consistently get oil fouls check valve seals

If you look just under the upper frame rail on the left side under the fuel shutoff valve there should be a plastic knob on the end of a cable in a hook shaped clip. This adjusts the mechanical idle. Correct idle speed is 1100 RPM.

Hi there and welcome to fixya,

I can share with your sentiment there. Here's are some of my ideas, you'll need to be patient enough though.

the jets you used, is it the stock replacement or a bigger one? I would recommend using the stock jets to eliminate the possibility of it being the cause. Tune your engine using a timing light, synchronize the carburetors so each intake manifold receives the same amount of fuel on throttle. Drain the fuel form the carb reservoir (or clean the whole carbs including the jets). Adjust the air-fuel mix to standard or 2.5 -3.5 turns out. Check for hose dents and check for proper plug firing.

Make sure cylinder compression is also good otherwise you'll suffer power loss on peak RPMs at high speeds.

The above process should eliminate any possibility with regards engine idling and poor idling.

To answer your question regarding valve clearance you'll need to download the manual to assist you on dissassembly. You'll need to remove the top cover on the engine and use a feeler gauge for adjustments. I'm not sure how to find the TopDeadCenter of this particular bike but the manual should.


Hope this in any helps you out,

RH side on the carbs under the throttle cable connection to the carbs. Screws in from below. You'll have to loosen the fearing to get at it.

a little bit is normal

check your clutch adjustment.

Try adjusting the clutch, if it won't adjust then the clutch is out, will it drive in one gear? if not the clutch is gone.

ignition timing and or carb adjustments will cause this problem.

If it's ignition-timing it's designed not to be altered or set, why do you need to set it?

If it's cam-timing i'll put a detailed explanation, let me know m8.

you can move them up or down in the triple clamps or if they have air fittings you can add or remove air from them but dont blow the seals out of them they will usually only take a max psi of 13
