Problem is worse the colder it gets. I leave the bike sitting at 2000 revs on choke for 5 minutes before I set off to ease the problem. The father seems to think she runs like a dream after I let him have a go on it, bearing in mind its a 10 mile journey to his house and it was warmer that day. It definitely gets better with time (heat), I just wish I had a temperature gauge to see what temperature she likes.

Just bought a K&N Air filter, an Oil filter and some more oil.

I'll give her the basic once over sevice before I faff about with anything else.

Anyone had experience with NGK Irdium Spark Plugs? I'm wondering (when I eventually replace mine) if they're any better than stock plugs.

So I understand that this won't be foc-u's first rodeo with stuttering FZS600s...

I've seen a lot of threads and I'd like a list of possible causes and solutions. I've trawled the threads and found loads of stuff but if I were to try it all I would be here for a year (I only ride bikes, and this is my only functional bike right now so I don't have a car to fall back on)

Standard issue, works fine with feathering the throttle but as soon as I try to give it full beans I get the dreaded splutter until higher revs and then it bursts into life suddenly.

I wonder if its something as simple as it being 1-2 degrees outside and my journey to work is only 2 miles?

Thanks in advance.
