thanks for the reply gents, the electrical fault: the bike rides fine until i hit traffic, the fan kicks in, i'm first at the traffic lights, lights turn green, fuse blows. i change the fuse, blows again after 10 meters. i put a 20amp fuse in to get to work, i get to work eventualy, i got home - another one fuse blown. so i can use the bike up to one point, when the bike begins to overheat and after the fan kicks in. AND THE GUYS FROM YAMAHA NOW ALL THIS. before i let the bike at yamaha, my neighbour - a car mechanic by trade- had a look, tried to find the short, but after about 3-4 hours he gave up baffled. ( all the street goes to him with car problems, he even fixed mine a few imes, so i trust him). then i decided to go to yamaha, hopeing they'll fix the problem quick. but hey... it did not hapen. and yes, we checked the fan and it seems ok. probably i'll go the garage tomorow and get the bike back and start again
