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.

SOURCE: no idle &bacfires on deceleration

hi mate on the carb you will find 2 screw 1 is for the idle and the over is for mixture the idle one will be the furthest out screw it in 1/4of a turns will the engine is running this will take the idle up on the engine and the backfiring is fuel in the exhaust not being burnt so on the over screw on the carb screw that in 1/4 of turns this will decrease the amount of fuel going into the engine if it still backfires screw it in 1/4 of turns again and see what difference it makes good luck

I need air mix settings for a 1996 zzr 250 kawasaki

it sounds like your low speed idle jets are still cloged as they are very small openings you may need to soak them in thinners then use a air compresser to blow them out ,and see if you can see through them ,i have found a steel guitar string the smallest can fit some of them hope it works cheers

Aprilia rs250 runs ok but wont idle

Hello kevin...the idle circuit on the mikuni carbs has most likely become restricted or you have a rich condition thats causeing it to flood at idle...These high reving 2-stroke engines never did seem to idle quite right..but man will they scoot!
Have you tried changing plugs? Go a heat range hotter to see if that helps? Check for vacuum leaks around the carb mounts... Other than that, you will have to remove the carbs and do some jet cleaning...a steel guitar string and compressed air works good to clean out those small passages.
Hope this helps and good luck with your bike.

My zzr 600, 1994 model idles a bit too high at 1500 approx how do i adjust this down and what is the correct idle for this machine ty tommyfour

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, my zzr 250 hadn't been started for about 8 months, so it fired up nicely with the choke on but once the bike warmed up I couldn't get it to idle once the choke was off, i tried more air to the carby...

Could be one of two things
1. The carbs are gummed up. Modern fuel will break down after only a few months. The idle jets are quite small and will easily become blocked. Strip and clean the carbs.
2. The throttle cable is sticky. Less likely, but possible. Make sure it opens and snaps shut easily.
What do you mean when you say you tried more air?

Hi ...... Wet your finger and see if the downpipes are warm/hot then try swapping the spark plugs from cylinder to cylinder. This will isolate bad plug or blocked carb ........... Let us know how you get on.

Idle speed problem

I had a similar problem, engine would fluxuate engine idle speed. I had to change the "Throttle Position Sensor." You might have that checked out.
