Hi all, I wonder if anyone had any thoughts about this:

I recently got an 04 plate yamaha Fazer fz6 600cc, and it was running fine for the first few weeks if running a little rich.

Recently its started stalling when I'm shifting down coming up to junctions and lights etc, and it seems to be that when the clutch is all the way in it'll stall. Generally seems to be worse when cold but happens >50% of the time. A bit unnerving at times!

I took it to a garage, who'd said yamaha had put out a recall on the throttle position sensor of this model, and the symptoms were pretty much what I'd been getting. They replaced it and it ran fine for a ride or two, before the problem came back.

Took it back to the garage who gave it another look over and couldn't find anything obviously wrong, said the the tps was working okay, and suggested a full service.
The only thing I'd noticed is that it tends to idle below the speed listed in the manual, and can drop to ~700 when shifting gear.

I thought I'd ask here before opting for the service ; particularly as it'll cost most of the value of the bike!

Thanks

Thanks for the replies.
It is fuel injected

No with the bike in neutral it doesn't tend to stall.

I'll have a play with the idle adjuster after work and run some redex through again.

How many miles has it done and when were the valve clearances last done?

My R6 had similar symptoms - would stall when clutch pulled in at junctions when it was cold. It was better when warmed up but over time started doing it when warmed up as well. It also ran a bit rough below 4-5k revs.

Had the valve clearances done and its fine again now.
Yes that sounds like what's been happening, definitely a bit rough in low revs.
It's around 25000 miles. Not sure if the last guy did the valve clearances.
Is it a big job?

I've turned up the engine idle speed and it seems better on a short ride.

Thanks all.

I think the plan is to check the plugs, check the side stand switch and then if no joy find someone to look at the valves.

A few after photos...
Trickling through traffic at rush hour, I'd slowed down to give way at the bridge, heard a beep, ignored it as you do, heard a lot more and a guy pointing so stopped and jumped off.
Smoke coming out from under the seat, a few flames so called 999 from a distance.

Looks like it could have been worse, fuel tank didn't catch, so maybe the guy up there putting cigarettes out in petrol is right!
