GSXR 600 Cutting out
Discussion
Hi folks thanks again for the info. I thought I'd sorted it as I found a vacuum pipe off when I took the tank off again. There's a tapered hose coming off the bottom of the air box that looks like it should be a drain pipe but it isn't it should be connect to the vacuum system. Got excited that this would fix it but no such luck!
Tested the coils with the multi meter and the primary readings are way off for all four. The secondary's are fine. It does seem odd that all 4 are off by exactly the same amount so I'm just going to double check with a borrowed multimeter later this afternoon.
I've checked the side stand switch and cleaned that as that's come up a few times online and all seems fine. I've had it on the paddock stand running and wiggle the stand about it has to be quite far down before it will cut out so I'm thinking that's ok. I'm guessing the side stand switch kills power totally so if it was that the rev counter would die too which it doesn't do when I'm riding.
To add another symptom when out testing yesterday I managed to get it to go past 7k by holding the throttle open. Previously I'd been backing off as soon as the power died but if I hold the throttle after a few seconds it will pick back up and go past 7k, usually with a couple of attempts but the bike then runs very hot, temp gauge climbs rapidly and when I braked hard to slow down all the electrics went gaga. Warning lights coming on,LCD screen displaying everything. Once slowed back down all returns to normal.
Don't know if this is part of it or something else!
Got the tank back off again last night went through all the electrical connectors found a couple grubby looking connectors which I've cleaned up so back out this morning to see what it's like.

Did you have any luck with this OP? I had a similar issue last night, my GSX-R600 SRAD was doing a pretty good Triumph impression for a little while, fired up as normal, but when I got out on the main roads it started to miss on one cylinder, and wouldn't rev above 6000rpm in any gear. I parked it up for a few hours while I was at the cinema, then on the ride home it was running on 3 cylinders again, letting off the occasional loud pop (not like a rifle going off kind of thing though). Every now and again, when closing the throttle and opening it again, it would run on 4 cylinders and briefly make full power, but before hesitating and going back to 3 cylinders. It was a slow and jerky ride home. Straight away I was thinking coils and leads.
This morning I whipped the seat off, lifted the tank and removed the airbox to look at the leads. Sure enough, the connector for the lead to the coil on cylinder 1 was loose. I snapped the connector into place, did a quick airbox and air filter inspection and put it back together, before taking it out for a quick spin around the block. Running smooth and fast on 4 cylinders, I let the engine warm through and gave it full throttle through the gears, runs to the redline smoothly and has no trouble at any speed. Normal service resumed.
