Hard to start when warm

ok guys just did a quick test tonight. i did a clear tube test (fuel level)
now this was done ONLY on carb #1 piston #1
and the reading was about 1/2" down from base of carb sounds like its not enough fuel?
i will check manual on this (read up more)

maybe thats why when i gave here more throttle it started

Please give me some sight on this matter Thanks Guys

1/2" is way too low. Should be more like 1/8".

ok guys a little update

the fuel level where all over the place but i think i gotem dialed in now.
also checked compression all good without carbs on 155+
spark check all good

thanks guys for the help and keeping my old dog on the road

here is a picture of fuel levels

These can get hot & become intermittent:

Ohm Checking Pickup(Pulsing) Coils

The pickup coils on the Kawasaki’s with the factory supplied electronic ignition can sometimes fail or become intermittent due to heat and vibration.

1.Trace back from where the pick up coils are mounted,(under a right side CD sized cover) locate and disconnect a small 4 pin connector. Using a multi-meter set on OHMS and range of 2K, check between the BLUE and BLACK wires(#1 and #4 sparkplug wires) for between 360- 540 OHMS.

2.For #2 and #3 sparkplugs the wire colors will be YELLOW and RED, again 360-540 OHMS. The 550’s,650’s & 750’s may be backwards to the Z1’s,Kz900’s,Kz1000’s & Kz1100’s.

3.If the pickup coils are suspect of failing due to heat, they can be stressed using a hair dryer without the need of the engine running.

4.A replacement set of pickup coils might be obtained from a dealer who serviced the police Kawasaki’s.

5. If replacement pickup coils are not available, your next choice would be to order a Dyna “S” electronic ignition system from www.z1enterprises.com It replaces the IC igniter with a smaller module located where the mechanical ignition advancer was mounted.

6. Checking with Kawasaki.com website has determined that the Pick up(pulsing) coils are available . The pulsing coil # is 59026-1133 and replaces the older # 1002, 1012 which were used from the MKII motors until the 2005 P24.

7.Check the small 4 pin connector that the pickup coils connect to for corrosion/loose pins too.

My bike requires a 1/8th blip or so of throttle to start when shes hot. no choke or nothin, just hold the throttle a crack and press teh starter down. Sometimes on super hot days the starter will turn over what sounds like 4-5 revoltions, but she fires off evertime.

I like my low end fairly lean tuned on the carbs, and it contributes to this symptom. Tuning the mixture screws richer some can make a difference it it doesnt mess with the idle/off idle performance too much.

Good luck.

an up date

its all good now
man she fire off with a little blip of throttle now
smooth all thru low and high power band like its a new bike now
it was mostly the the low end giving me trouble but not no more with the correct fuel levels
and while i was taking carb off decided to replaced the rubber intake boots and air cleaner ones
now i am happy runs like champ now!!
thanks guys for all the help

now lets get some miles on

So do you have to keep it filled with gas during the tube test? Just started with my carbs last night, and not sure if im doing it right.

The fuel should be free flowing (pri), or prime mode selected on the vacuum style petcocks, or ON with teh regular on/off style.

The tube indicated the level in the bowl as it comes to a stop via the float valves.
Being close to spec is generally good enough, the most important thing is that the fuel heights are as close as possibly identical to eachother.

GOod luck.
