Finally traced a strange feeling of riding what felt like a horse ie a lollopyand undulating (not vibration) to the rear wheel, by running the bike in 4th gear whilst jacked up in the air.Thought thats good, now i know what it is, and took the wheel to have it dynamically balanced, but when her indoors went to collect it for me they said it would have taken so many weights (130g i think she said) that it would have been too asthetically unpleasing (tyre blokes words) so he wouldnt do it.
Ive spun it up with the spindle clamped in the vice and it doesnt look that bad to me ie.about 1/2 mm run out eccentrically and same side to side.
My question is would it be worth giving it to a wheel right to let him try and true it more or or have i got to say goodbye to another 200 squid and have a new rim etc.? What else can make it SO out of balance , i dont think ive ever had to have a motorcycle wheel balanced ever before.
The wheel is a chromed steel dunlop rim ,18" dia with one security bolt about a third of way round from valve, fitted with 4" trials tyre, which has an even gap round the perimeter line.
Cheers Spyke
PS the wheel was not new or rebuilt when i fitted it .
