Front and rear wheel bearings? Is their any play or when you spin the wheels is their any clugging? Changed all mine out for industrial machine bearings with steel seals instead of rubber/plastic ones( seems to be smoother)
>> I cannot detect anything but then I wouldnt know what poor/worn bearings look or sound like. Bike just passed an MoT this week so??..
Wheel spacers, worn, cracked? Spindles worn or dirty?
>> How would I find out whether spacers worn? Wheel spins freely and no unusual binding , resistance or sounds.
Fork oil degraded? If degraded in one side more than the other will throw the balance of the front end off? I upgraded my springs to hyper pro to stop the diving and change the oil in them every 6 month
>> No idea and would be a big job for me; I dont own fork holders, t-handles, vices, etc. as mentioned/required in the Yam Shop Service manual (section 7-45)
Front tyre uneven wear? Throwing the balance off again?
>> Nope.
Wheels balanced? Should really have the balance checked every time you have anew tyre put on but believe it or not this is overlooked quite a lot?
>> Dont know. will need to ask a garage to balance; again I dont have the equip for this
Handlebars bent? Again balance is out?
>> No
Front spindle over taught which could crush against the bearings and would cause a lot of friction resulting in vibration? 67nm is perfect.
>> Spindle - see above. both wheels "seem" - to me - ok
Brake caliper piston jammed up and not retracting so pads are wearing uneven, again causing too much friction causing vibration??
>> Brakes are fine
These are more than tweaks for me - probably over £400 of garage labour time (8rs) alone. Just to diagnose before any problem gets fixed - at extra cost. Bike only cost £1700. Two work colleagues owned Fazers and complained of numbness too, they suggested getting thicker neopreme grips??
Also, what I noticed is that at around 50-60mph, arms sort of relaxed, if I make small, minor, very gentle forward and back movements of my elbows, probably 1cm, the front end feels wobbly and unsafe.???
