So, after 6 months of perfect running, my Fazer has become very hard to start.
2006 FZs 1000, 20k miles.
The battery turns it over just fine, and from cold, on full choke, it will catch for a second, but before it will idle, it dies. And then it will spin and spin and make no attempt to fire.
I checked the plugs (CR9E) and they look like they have been there for a long time but were a good colour, sort of grey to tan with no soot and dry.
I thought it a good idea to change them anyway, so a set of iridiums went in this afternoon, but still the same.
I took out the air filter and it is dirty, but not blocked by any means.
I tried it without the air filter too, just the airbox lid on and same behaviour.
I also took no. 1 HT lead off and put in one of the old plugs and turned it over with the plug on the cylinder head and the spark looked good.
Am I missing anything obvious?
Cheers,
LD
