Starting issues

[don rocard]

Go get a new battery and be surprised.

I have had similar experiences before Mike, my GSXR750 would turn over fine when cold but it would not want to 'catch'. Changed the battery and never had the issue again.

[Mikkel]

Sounds like I know what to do on saturday then

Test (and probably change) my battery.

[Mikkel]

Stuck a multimeter to the battery this morning.

It read the following voltages:

1. Ignition off - 12.66 V
2. Ignition on, lights off - ~12.4 V
3. Ignition on, lights on - ~11.4 V
4. Ignition on, lights off, starting 1st go - ~10 V
5. Ignition on, lights off, starting 2nd go - ~9.8 V
6. Ignition on, lights off, starting 3rd go - ~9.5 V - the bike started, but it's pretty mild today.

So do I need a new battery?

Also, in order to get to the battery I took the bolts off that holds the rear tank brace. When I went to fasten it again I snapped one of the bolts - I wasn't applying much force must have been old/corroded/fucked... Anyway, I'm left with 2 half bolts one of which are sitting in the thread on my subframe. What's the best approach to get rid of it? (The bolt, not the subframe )

[Mikkel]

Thought I should just follow up on this.

Took the bike in, got a new battery installed and the problem is gone.

Might want to check your regulator too... Not sure how they are on the 250, but the zxr400 (under the seat) I had ran 2 batteries into the ground before I found out that the regulator was screwed. When I broke it open it was corroded etc... and showed the same symptoms as yours. I can only assume that it wasn't charging the battery correctly unless it was dry and when crnaking in the morning UGH... Was a bastard when it'd been cold outside, I'd have to bump it to get it going in the morning, then park it in the garage at work, before it'd start fine in the evening. The following morning it was back to screwed... Just something else to check...

good to see you have your problem fixed. I used to have the very same bike and it did take alot of effort to start sometimes. I replaced the battery as mine was old and crappy but blamed the carbs, touchy wee buggers in those things. Got them cleaned up and tuned and the bike went amazingly since then

[Mikkel]

Carbs are fine I think - she definitely pulls alright!

But she's not happy on these cold and wet days that's for sure. But the battery seems to have sorted it out though.

just a thought for all who read this thread
if the vacumme fuel tap gets stuck , which they can. youll find it winds over fine , trys to fire up but may keep dieing, after the while the tap should open correctly and fuel will flow correctly .
can also try turning the tap to the pri position

Turning tap to prim helped my sons ZXR especially if it hadn't been run for a while, seemed to lose fuel from the carbies somehow.

they dont loose the fuel but the fuel only flows when the engine runs
thus the vac fuel tap .
they get sticky when sitting a while and it takes a lot of winding over to get the tap to open to let the fuel flow
you can flatten a battery easy trying to get a bike going
pri on the fuel tap lets fuel flow even when the engines turned off
