annoying noises

[tony]

hey guys oppinions needed
first how noisy are these fzr,s
i have whining noise when im riding now bike finished i wish to address this matter
when in neutral its ok
when on rode its all through the gears
jacked bike up and ran through the gears all ok
so i am assuming it to be wheel bearings
how is the best way to check the bearings
any feedback welcome

I have FZR EXUP for last three days.. some short stints on the highway revealed some minot droning @# speed. I have check for deflection of bearings.. O.K. spun up by hand ( weight off) shows no dragging brakes, roughness or premature slowing down so I assume may be chain and intend to allign and lub before my 800 k road trip today
lve in 2 hours
hope this helps a bit.. I'm no expert so grains of salt apply

Best thing to do is back track, on the recent changes you have made tony. Front and rear sprockets, chain. What bearings did you replace?

[tony]

rechecked bearings in font wheel it appears these new bearings are a fraction larger on the internal diameter of the inner bearing i tried my pin on my other spare wheel and it is tight in the bearing it just shows it pays to get genuine parts

Tony,
Yamaha bearings have a rating C3 or C4 (that is tolerance of fit & max rpm) if this old head of mine remembers correctly when you buy replacement you can order bearings with that code as well to get the exact same as OEM.
