Howdy from New Zealand A mate of mine has a 2006 TTR250 which he purchased new in September 2006. Every since he has had the bike, it has had problems. It was "surging" at "tootling" speed at about quarter throttle. Eventually the shop concluded there was a carb problem - over the past 8 months they have replaced the main jet, drilled out the pilot jet, replaced the pilot jet etc, and it's still no better. My mate has an older model TTR250 with exactly the same carb, so put the old carb on the new bike and it went absolutely fine. Yamaha's pathetic excuse for this problem is that the bikes now have to be tuned to meet stricter emission controls and so probably wont run 100% right. Also they say that no-one else probably no-one else with that bike "tootles" around at quarter throttle so wouldn't encounter the problem. They dismissed that the bike went fine with the older bike's carb. Has anyone else has a similar "surging"/carb problem with an 06 TTR250? Cheers M
