QuestionHi Samuel,
I thank you for your offer to assist, this is a doosy of a problem, are you ready ??
OK as a follow up to a previous thread I posted on the Kawasaki Australia Forum site :-
http://ksrc-au.com/phpBB3/viewtopic.php?f=21&t=17274&start=0&st=0&sk=t&sd=a
My bike was running rough under load, and cutting out in the wet (Both problems were dodgy plugs and leads, and carby synch required), as seen in the other post, the carbs have been serviced, valves adjusted, and was running great, except it was overheating after this work was done.... Never did this before on the same run to work, the fan was never required to bring the temp down....
I have now fixed the overheating (Refilled coolant, removed / bled out as much air as possible, found a broken fan switch on the radiator (Temporarily wired the fan on permanently until I source another radiator switch)
I am still have the following problem though, even the garage that did the other work could not work it out, can anyone use their technical savvy to suggest a fix please ??
Here goes, the symptoms :
Starts cold on minimal choke for 30 secs when cold, then idles fine, runs a treat, pulls great now under acceleration.
When warm / hot (Temp Gauge can only be reading 1/4 or less when the problem shows itself), if you kill the ignition and try to restart, the bike will try to catch, but using any variation of choke or throttle or both, or just using the starter button, the bike will not start.
Then, during the same time period of trying to fire the bike up, if you leave it and try starting again, you get a high pitched wine from somewhere in the circuit, and no starter motor action, turn it off and leave it 2 - 5 mins or so, the starter motor will turn over no problem, sometimes not.
Today, when I was trying again to start the bike after trying all of the above, the rev counter went up to 4000 rpm every time I pressed the starter button, again with no starter motor turnover, dash lights would dim quite a lot, this is the first time it has ever done the rev counter trick.
Halfway through the above hassles, I tried restarting again,(Bike was still warm), the bike fired into life with a smooth idle, right off the starter button, with no choke or throttle.
Bump starting does not work, when the starter is not able to turn over, the rear wheel just slides with my full body weight jumping onto the bike when I dump the clutch in 1st gear after running down the road, I have successfully bump started the bike like this when I first bought it.
Even when I use jump leads from the car battery, if the bike battery is getting tired, does not improve the situation.
I reckon I will be genuinely shocked if there is a logical fix for this .... I can't afford any more garage bills, got to suss this one on my own ....
Thanks again Samuel, any advice would be greatly appreciated.

AnswerOkay, this may sound kind of wierd but here it goes... Under a cold starting situation the starters brushes are cold as well once you initially start the bike under these conditions they warm up, quickly I might add especially under a hard start, what I would do if I were you is simply replace the starter brushes and this should fix your problem.
