| 1999 FZS 600 - Low RPM bog down, ideas? |

I use my FZS 600 '99 for commuting daily and recently it developed a problem with a noise coming from the right hand side of the engine. I only notice this sound when the bike is started from cold, and the sound reminds me of a tractor: clattering like. It doesn't happen all the time, and is faint. Comes and goes. Not constant.
I first noticed it/it started happening after I washed the bike with a hose pipe and then used the Bruhl dryer straight after and then started the bike to remove any remaining droplets of water. The engine temp light came on, and the bike sounded rough. The first few rides after that were very bumpy, and the bike ran rough for the first mile or so (juddering, low on power, surging and then perfectly fine after about 3k). I drained some fuel out of the float bowel and it was clear and smelt of petrol, thinking I'd gotten water in the carbs or suchlike. I've not done anything other in that side of things.
A week later the bike starts fine and starts first time, I've changed the spark plugs and that helped but the noise is still there and the bike is still low on power from cold occasionally (not every single time) sounds like it wants to die and sometimes tries to but doesn't and keeps running. Its nowhere near as bad. Seems like an intermittent issue. When it plays up it goes through a phase and then suddenly everything is fine power wise and it runs normal. Always below 3k and in first (not noticed an issue in other gears). Runs fine, reaches 70 mph etc perfectly fine. Goes to the rev limiter. No stutter on throttle input.
Before I ask the shop to take a look what can I do. HT leads, coil pack, air filter?

Hello
Bike has been off the road for 18 months, finally managed to solve a leaky carb issue and rebuilt the bike. Had a leak on the tank valve, so emptied the tank and put in some fresh petrol when I changed it out.
Bike started, ran on 4 cylinders for a while, and now is down to the left 2? Seems to be running quite rich as well, I can smell the petrol as its running.
Any suggestions? Would very much like to get it back on the road and MOT'd soon, ready for the summer.
Thanks in advance

I’m thinking of replacing all the visible fairing and side panel bolts/screws.
Do I go via Fowlers or has anyone got any better suggestions?
