Before you have a shot at me....I already know I should have bought a Kawasaki......................shit happens......
Been having problems for a while with fouling plugs...get it going and it runs OK but wont start next time....new plugs solved problem for a time....took off carbs cleaned , checked etc replaced and balanced etc...still nothing...checked leads no spart on 1 & 2 cylinders....leads checked out ok individually...next took off coil packs....cylinders 1 & 4 go to 1 pack and 2 & 3 to the other...Packs checked out OK...whats left??? has to be the Igniter???? Any way to check this out????? any suggestions or anyone else had electrical/similar problems with Gixxer....If its the igniter any suggestions where I could pick up a second hand one.....This is really pissing me off as this is the second ride day at oran park I have missed in as may weeks.
Thanks

old fuel??
Buy a Kawasaki. and a fuels injected one.
Dude at work says he swapped his plugs for normal ones rather than the iridium ones. because they didnt last very long.
happy hunting. he also replaced a coil pack, about $150.

The H model GSXR 750 I had years ago developed a habit of eating rectifiers, that would cause all kinds of weird symptoms, might be worth a look.

SORRY...TOTALLY FUCKED UP TOO MANY LATE NIGHTS
1 & 4 AND 2 & 3.. ARE CORRECT
I will pull of igniter and take it to be tested...Carbs OK...Coil Packs OK Leads OK Clips OK wireing OK I have always run BP Ultimate 98 without a problem...
If it aint the ignited then I'm Totally Fucked.

OK I'm running iridium plugs cr9eix which is the equiv of cr9ek...we have double checked everything once more and it now looks like the plugs...the iridiums appear to spark on the "inside" and not from the tip..I am going to get standard plugs and see what happens....anyone else had same problem or an explanation...the last 2 sets of plugs were iridium and low kms before they stuffed up...I didnt assume plugs because of low kms...we get plenty of "test" spark using a wire stuffed in plug lead to bike frame so ruled out igniter etc....i'm fucked if i know

Even my KX 2fiddy only gets a tank n a half out of the first [and last] 3 Iridium plugs!!!
would start fine and go like stink .......then die altogether without warning never go again till the plug was changed!! (only 1 pot after all)
Put platinum [CR9EV I think for yours] in.. work better / cleaner / longer than standard but don't shit themselves like iridium's seem too!!!

Thanks to all who replied with assistance.........It wasnt electrical....a mixture of Irridium plugs, petrol,carb balance, petrol tank filter and tune up.
Petrol tank filter had some gunk in it restricting flow at times....Pissed off irridium plugs and running standard NGKs.....Petrol running was 98 octane manual suggests 91 only - ow run 91........ carbs balanced and tune up .....all is well now.
Thanks again
