Grendel, check the swingarm for Play. up and down any more than 5 mm and its bushes and bearings, anything up to 90 quid to do yourself.... if there is ANY side to side movement then there is wear ( get him to hold ot up in the air on the sidestand to check or alternatively take a mate with you who knows about Bikes....... Swingarm bearings again not too bad, bit of a cow to strip but doable at home. parts available from
Wemoto Home also check wheel bearings and chain n sprockets.
Make sure the engine sounds 'healthy' no bad Knocks, rattles or unusual taps. ( they aren't the quietest bike in the world like so again, preferably take someone who knows XTs)
Make sure it goes into all the gears smoothly and the gearchange is smooth and positive both up & down the box.
Most Important.... Take Your Time. ask questions Be direct after all your not a mind reader and once you have paid your Money you own the Bike.
XT's are a strange Beast, an aquired taste, but an addiction, an addiction that will make you look for exscuses to take the bike rather than the car.
Dont say I didnt warn you about the addictiveness...there is no XTholic's Anonymous! we dont want to stop!
