2004 zx10r. Have had starting trouble with it for a while. Iv got servo eliminator and tre on the bike no other electrical changes. fires up usually really quickly in the morning and after a short ride maybe 5 miles I turn it off. after that it will turn over and over and not crank.. Usually it i try it then wait a min or so and try it again and again after about the 5th time it will crank right up. the battery is only about 6 months old. I keep it on a charger anytime im home. So far I have replaced the regulator and the stator. The battery is holding a charge at 13.3V and while cranked it stays up about 13v. Im tired of letting everyone sit there and wait on my bike to start. Any help would be greatly appreciated.

Check the kick stand switch. Could be sticking because of grime or even loose. Read where people have had issues restarting and it was the kick stand switch.

Couple of things here.

First, the term "cranking" it means engaging the starter. So it's cranking (turning over) just fine and it's not "firing" up.

Second, the rectifier and alternator (stator) have nothing to do with starting it. So replacing those things wouldn't matter anyway. Same goes with the battery. If you've got enough voltage to crank it, that's fine.

Third, the kickstart switch is a good idea, but won't effect this issue. If that was bad, the bike wouldn't crank at all as the starter wouldn't even engage, let alone have problems firing.

Do you let the system fully complete when turning on the ignition and it goes through the self-check? Do you hear the fuel pump priming as this is happening and you hit the starter only after that is done? Have you tried cracking the throttle slightly as you're cranking it over? Try that and see if adding some extra air when trying to start it hot helps at all.

When was the last time the injectors were cleaned? Definitely sounds like a fueling issue. But hot starting issues are hard to diagnose. Time for some lovin' on the bike. Need to check and replace your air filter. Clean your fuel injectors. And synchronize your throttlebodies while you're at it.

Your right Skydork. I sped right past "after that it will turn over and over and not crank". Not the kick stand switch.

Check the sock in the bottom of the fuel pump assembly. Drain tank. Unscrew the pump. Remove two screws on side of pump assembly. Carefully pry and pull out. May have junk in there. Worth a shot. And it's an easy fix.
