I suspect the carbs need unblocking and cleaning. I haven't run the bike for a while, and now it won't idle.
Is there anything I should look out for? How long will it take? Any special tools or parts I should have first?
Thanks
I've encountered a similar problem.
Left a fazer stood for a couple of years, and it wouldn't run right.
Ultimately I had to:
Take the tank off
Take the battery off
Take the airbox covers off.
Release the air box and pull it back
Release all the carb rubbers
Disconnect choke and throttle cables
Pull the damn carbs out
Take off the float bowls
Clean all the jets out and the fuel cut off needles
Try and clean out a bloody jet that was in fact a blanking jet and didn't have a hole in it to clean out... that took ages
Blow out all the drillings with compressed air and carb cleaner
Put it all back together
Balance the carbs, and check the TP sensor
In any event it worked and the bike ran fine, but it was a fag of a job
Now I charge the battery and run it once a month and I've put some Redex in the tank.
My conclusion is that they don't like being stood for long periods of time, well at least not the carbs.
Actually that's not true, the other thing I had a problem with was the plugs.
It ran fine before than I left it stood for a couple of years, and then when I tired to start it one of the plugs wouldn't work, and my mate had a similar problem on an ER5.
Why a plug should fail when you leave a bike stood is beyond me, but still there you go.
