Starting problems So for the past few days I have been having a starter issue, I think at least. Basically when I go to start my bike it begins to turn over, then it gives up. So I release the button, push it again and it slowly gets up to speed and starts up just like normal.. Any thoughts, is my starter giving up on me?

Re: starting problems
Have you fully charged the battery? Have you cleaned the lugs that connect to the battery and the battery terminals at that same place? I went to start my daughters 96 cbr900 on Thursday and had to charge the battery and noticed how dark or oxidized the terminals and cable lugs were and cleaned them before re attaching after charging the battery. It may also be a build up of carbon (?) on the starter switch itself caused by arcing and that wuld add resistance to the circuit impeding the amperage and voltage to get to the starter.

Check your ignition components for condensation. If you wash the bike using water especially around the motor, you should promptly dry it thoroughly before starting it to avoid the possibility of condensation caused shorts in the ignition system. I personally use a leaf blower to dry mine and let it sit in the sun for a while to make sure it's dry. I think you will find condensation is your problem. Good luck and safe riding.
Hi T_mutis, it should be noted that in order to "PROPERLY" diagnosis any electric starter issue it is "IMPERATIVE" that you begin with a fully charged battery 12.5 volts or better and be able to pass a proper load test, and the usual suspects are:
1. Battery terminals have loose or corroded connections.
2. Battery cables faulty due corroded or broken internal wiring at the cable connector especially the "NEGATIVE" cable which needs to be checked at "BOTH" ends.
3. Battery voltage, 12.5 volts or better,to the main circuit breaker to the ignition switch to the security/ignition fuse to the TSM/TSSM module to the engine stop/run switch to the starter button to the starter relay to the green wire that connects to the starter solenoid has dropped more than 1/2 volt.
4. With a voltmeter connected to the battery, the ignition switch in the on position, the kill switch in the run position, the starter button depressed, starter engagement should not bring voltage below 8-9 volts.
If a lower voltage is produced a proper battery load test should be performed with a load tester to validate battery integrity or battery replacement.
5. Faulty starter relay, check continuity.
6. Faulty starter solenoid, check contact plate and shoes for excessive electrical erosion/etching, refurbish as necessary or invert contact plate and use the virgin backside. Check contact shoes for being loose. Replace solenoid if the negative function is still a final outcome.
7. Faulty starter, bench test starter with a 12-volt battery if negative function check, decontaminate and undercut armature commutator segments as necessary, check segments with an ohm-meter probe each one and the segment next to it for shorts. Have the armature tested with a growler and field coils, and brush plate with an ohm-meter for opens, shorts or grounds. Replace brushes if less than .438" It is generally cheaper to overhaul/refurbish a starter motor than buy a new one.

I had the same problem with my 07 cbr but i found out that it wasn't the starter relay, the battery was just dead and i tried to recharge it but it was still dead, so it needed replaced with a new one. once this was done the bike started fine and the buzzing had stopped, so you should give that a go!
Hi, I would start by checking to be sure the battery has a good enough charge, if not then locate the starter relay and try jumping the two terminals on it and seeing if the bike will start that way if so then you will need to replace the starter relay. good luck
