My one has done 10,000 km`s now...and had 3 oil changes, with filters..
But the engine is really sounding like a ten year old bike..
Last night while at the stop lights in nuetral, i could eassily feel the engine clattering (like metal to metal, erratic not continuess clattering, clutch in or out) it`s actually embarassing reallly.....and that was with a full face and visor down....engine temps in town, running at up to 105 c and out of town 85-96 c....WHEN is she going to blow i ask my self....
