checked chain chain is the rite tightness....ive put a screw driver down by the shaft and ran the bike on paddock stand while putting my ear on the screw driver doesnt souund like any bearing noise is coming from shaft.im baffeled......

its defo not not brakes binding...im wondering if it could be drive bearing on where front sprockets fits..but not 100% where noise is coming from there....i stripped front sprocket off theres no play in shaft etc....i even ran the bike with out front sprocket on but no whinning noise came from it then(but there wouldnt be no load on it due chain etc being taken off)....ive even changed the rear wheel needle bearing...

i have 2000 plate r1 with 11000 miles on the clock.the problem i have is i have a whinning noise coming from the left hand side of the bike.. if i accelerate and the faster i get the noise gets louder and its still there if i decluch it and free run it.. i have changed the chain and sprockets as i was told it could be them.. if some one can help plz do as the good weather is coming and this noise is doing my nut in
