Hi, I wonder if any of you have any ideas on what may be causing this? I've been running my 99 FZS600 throughout the winter with no issues but in the last week I've noticed that there has been a funny problem starting. Intermittently it decides that it won't fire when I first press the starter button, it usually does on the second or third try with no problems. That issue hadn't really been bothering me too much as it always started, but I popped out on it at lunchtime and on the way back the engine just died. I pulled over to the side and it started again on the second or third push of the starter. I'm off tomorrow but ideally id like to work out what might be causing this over the weekend. The problem is that it doesn't happen consistently, most of the time it will fire first time and its never cut out on me before today.My primary suspect is the spark plugs, I had them out last year for a clean when I was servicing the bike but it may have been a few years since I've replaced them but I'm not sure that would have caused the bike to cut out. Other than that would I be looking at fuel pump, coil,cut off switch and ignition switch as the next likely suspects?Anything else I'm missing?thanksStuart
Carbs haven't been cleaned in a while, possibly a few years. Would this cause this type of issue though?
Last month I stripped down the r/h handlebar controls and cleaned up the starter button contacts as I had to wiggle the starter button a bit to fire the starter. It is possible I might have hit something else there as well. The ignition barrel is a bit worn anyway, or it might just be the key, I usually need to give it a wiggle to get it to turn. The green ignition light on the dash never went out when it stopped though, could that still be an issue?
I did fit a pair of R&G heated grips a couple of months ago, and wired to the fuse box. Could that potentially cause any problems?
I've got an arse puckering 20 mile ride home on the M8 to get through first though! Not looking forward to it.

I was thinking more of the cutoff switch on the controls, just incase I've done something to the wiring when I've been around the ignition switch.

I had similar issues, quickly discovered a loose battery terminal.Start with the simplest things first.Good luck

Think I've worked it out, got the bike home and started fiddling with controls and wiring. Found out it would stop whenever I fiddled with the ignition switch so I'm pretty sure thats the culprit. Are the replacement ones from wemoto and MandP good quality or is it worth going for a yamaha replacement?

The generator only supplies the regulator that charges the battery.Try it?
Sorry, I wasn't clear. When I pretty much even touched the key, or knocked the ignition barrel the bike cut out every time i tried it so I'm going to start with that. When the bike cut out I was going through a road that was getting resurfaced so there was a few bumps around so that makes sense. I tested the R/H switchgear thoroughly with a multimeter and it was all working as it should and there didn't seem to be any dodgy connections. I ended up just getting one from m and p on ebay, fingers crossed it'll be in on monday/tuesday hopefully. It'll be fun getting the bugger out though, looks a bit tricky with the anti tamper bolts.The rest of the bike needs a bit of a tidy up, its been doing a fair amount of miles recently with the mildish weather. I'll give it a service in the next couple of weeks, the inlet rubbers also need replacing and I might as well do the carbs while i'm in and around that area as well.Thanks for your helpStu
