Stuttering

[nic_oz]

Hi

Just today the 900 started stuttering when idling, I noticed this about 2000K ago and it went away after a little while and didn;t think much about it. This time it doesn't want to go away.
It doesn't stall but just hangs in there, tried increasing the idle doesn't help. It's still ok while riding though.

Before I book a service and let the mechainc pull it all apart $$$$ , is there anything obvious I should check ?

I've looked at the air filter. it's a bit dirty but still ok.
I did notice there seems to be no fuel filter, could an injector be blocked ?

Thanks

Nic

The injector would be the first thought, you might try running injector cleaner for a couple of tankfuls and see if that will do it.

Yes, good idea, I've also just read about a can of carby celaner that you vaporise in the air box while the engine is running.
I'll go to an quto store tomorrow and get both an see how it goes

Man. Carbs aint injectors. A carb cleaner going through as vapour will do bugger all for your pressurised injector. They need something in the fluid they're squirting to clean them, not some magic mist passing their ends.....

Good point andyj.

First thing I'd do is have a look at the spark plugs. May even be a loose plug top or dirty connection - and if the problem appeared then went away before it could be as simple as that.

The carb cleaner wasn't fopr the injectors !!
I read somewhere that gunk along the sides of the carb can also cause idling problems by impedeing on smooth air flow.
I was going to get both, carb cleaner and injector cleaner

I just realised (after a good nights sleep ) that both times this has happened I was on reserve, so I think the next step is a fuel tank flush/clean
