Hi all, first post! Got myself a 1999 Bandit 600s. I'm riding it to work and back which is 30 miles each way. I have noticed that for the first five miles of the journey the engine does not run at all well below 4000rpm, so I have to keep the revs up when stopping at traffic lights etc. It's juddery, hesitant at accelerating, and will not idle. Once I've gone on a good long blast along the M4 into Bristol it's all fine. The bike is a German spec import and as such has no carb heaters. I am wondering if it could be carb icing. Does this sound likely? Or are there any other theories? I replaced all the spark plugs when I first got the bike, so that rules out them I reckon. Thanks for your help Luke
