i have recently bought a 1999 fazer 600 with 10,000 miles very clean but have a couple of problems when i start it i need to give throttle a small twist as it will fire but not start with choke alone also in traffic as i ease off throttle and on again bike will not accelerate cleanly feels rough .I have changed plugs cleaned carbs and replaced inlet rubbers as old ones were perished lovely bike just need to sort these things out, any ideas thanks in advance Dave
