Hello all, my names damian and im new to the forum.
So i recently aquired a 2002 zx12r with roughly 14k miles, the engine build seemed pretty extensive, je +3mm pistons, built/ported head, cam gears, nitrous, air shifter, myrtle west swingarm, pc3r, msd launch control, etc etc
the bike starts up cold just fine, little hesitation, but after maybe one or two cranks (@35 degrees) she fires up and idles great. once she is up to temperature i will have slight hesitation from idle to 2500-3krpm then she starts pulling wonderful.
my problem is when this bike is at normal operating temperature i will shut it off, go to start it again and it will chug slower than normal like a bad battery almost, or like the ignition timing is too far advanced. But if i let the bike cool down it will start up no problem. today while trying to do some diag i was riding it around the block a couple times and temp got to about 3/4 and then as i was about to shut it off the fans kicked on.
This is driving me nuts trying to figure it out, battery, rectifier, stator are all new and wired correctly.
so heres a question, this problem leads me to advanced timing possibility, too advanced keping it from being able to hot start
Does the coolant temperature sensor have anything to do with timing or fuel on these bikes, is there a diag procedure to test these on the bike (resistance values etc)
the bikes tune is a mess on the power commander 3r, and in cell 0% throttle 500rpm it shows a fattening of 5, which doesnt seem normal to me. i dont want to erase the map and start over, but if i was to post the map would someone be able to tell me if it looks right on a larger bore zx12?
i apologize for the long post but im trying to provide as much info as possible for you kawasaki gurus to shed some wisdom on me, wanted to say thank you in advanced and i hope i can find the answers to my woes.
