Owned XTs in UK for several years, and especially liked the last one there an XT600E. Traveled about 12k miles per year all over the UK. Moved to Cyprus last October and bought my XT660R new here in Cyprus last November. Have spent the last six months trying to get it to run smoothly with a steady throttle (surging/hesitating at all revs and in all gears). With advice form this website and a friend in the business I have been adjusting the CO level and now have a -13 which is just about manageable although town and off road riding are at best tolerable and at worst dangerous. No help from the dealer (this is after all Cyprus) and no where else to turn!!!. Have written to Yamaha Japan with no response. Not fit for purpose and a blinding disappointment when all the other XTs have been so good (perfect). If you've got a good one then make the best of it cos when they are good they are very very good but mine - a waste of money. If I could get a decent price I'd swop it for a used 600E tomorrow.
