GSXR doesn't start.

Fantastic

Went to start the bike today, clutch in, starter turns over, but you are met with a massive clunk noise, it turns over da da da donk da da da donk

Tried choke, applying throttle, upped the idle speed a little just in case.

Battery is perfect, 13.0V showing.

I got it running, but it has this issue with the clutch switch where it just doesn't work sometimes, so got it in gear and it cut out.

And repeat.

Shit mate. How annoying.

I wish I knew the answers but all I can do is give ya a bump!

Saying that Paddy, is it not time to trade that one in for another, seems like it's just a problem after another.

At least the fork seals aint forked anymore though

Nah, i'll see this bike to the end.

Aside from the little issue of it not working, its great.

A clutch switch is usually a very simple, small switch. Similar to a front brake light switch.

They do occasionally fail, usually by the small switch inside sticking. I have had results by taking them apart and cleaning them, but it isn't an expensive bit to change.

If it was the clutch or sidestand switch the starter motor would not operate at all.Both cause the FI to go into 'limp-home' mode if faulty.

Sounds more like the sprague clutch taking the rotation from the starter motor to the crankshaft.It sounds like it is not engaging correctly.

I recently found a fault with the sidestand switch on a GSXR600K7.The wire was chafed through where it went between the swingarm and the back of the crankcases.It should measure about 6.8k ohms one way but not the other.This is why it is not possible to just short out the connection under the tank as this will restrict power until fixed/repaired/replaced with a diode and a suitably sized resistor.Or a new switch.

If the starter solenoid was suspect,disconnect the heavy duty lead going to the starter motor.Connect a multimeter across the heavy duty posts of the solenoid with the meter set to resistance.Press the starter button and watch for a dead short/zero ohms indication.If there is any resistance higher than a few ohms the solenoid is FUBARed.Placing a screwdriver across the terminals should start the engine if the solenoid is still suspect.But this does not do the tool any good.

If you try to bridge the terminals on the solenoid make sure you use a rubber handled screwdriver and you don't do it if there is petrol vapour anywhere... kaboom!!!!

[Kickstart]

Hi

A half turn over followed by a thonk sounds to me like a cylinder is full of petrol. Leaking carb float / leaking injector. However if this is the case after the first attempt it will just go thonk and won't turn over at all.

All the best

I'll try and get a video of it... it is actually behaving itself now, but it will die again and I'll get a video.

How was it this morning dude ? Did you get in OK ?
