Guys, thanks so much for this advice. I haven't had my account set up to the right email and haven't seen them until now. Thanks for the carb heater idea Slasher.... looking into it now - possible for next winter.
I bought a fzs 600 2001 - 13k on the clock, and I've been running it every day faultlessly for the last five months (actually had a week off due to snow). Excellent bike. I did get the carbs rebalanced and the rear piston kit replaced for new as it was full of crud - Dudeness .
A home mechanic messed around with the carbs so idle was way up at 2k which made me nervous buying as thought it was hiding something worse (was a [size=0.7em]bargain[/size] though and the right colour - black - and the seller was 10 miles away).
After a balance it rode and pulled away perfectly, enough to tag the CBRs and Street Triples off the lights. New back tyre worn in a few weeks ago and then some idiot knocked it off the centrestand outside my house - no off-street parking

Please see my new post about replacing handlebars and the Renthal choices on offer. Looking to fit them myself and and bend liquorice OEMs back into shape. [size=78%]Possibly for sale - the bend is v minor and they're expensive as new oem.[/size]
Again sorry not to reply or acknowledge the above advice. It would have saved me some stress when buying. It is a truely great bike though, good for pillions, punchy low end and then another little boost past 8000 revs.... smiling every day now.
Cheers.
Revilo
See you on the A3...
