Had the front wheel on the SOBeemer re-balanced this morning as I was getting significant tingles from the bars at certain speeds giving forrard and aft oscillation (Long technical word for shakes) at the fork lower sections, visible from on top at speeds on good surfaces. 10 grams out was the verdict, rectified and all now fine at all speeds up to (ahem!) mph. What I was interested in is how much excess weight would have been off centre at the periphery, so to speak, at that 10 grams at given miles per hour? I know there's gotta be a formula somewhere for it. Anyone know? -- -- Robbo 1500GL 1988 Goldwing (Rebuild in process) BMW K100 RS 1984 "Fairly Quick" status. Silver level BotaFOF #19.

Aha! You might be correct. -- -- Robbo 1500GL 1988 Goldwing (Rebuild in process) BMW K100 RS 1984 "Fairly Quick" status. Silver level BotaFOF #19. E.O.S.M 2001/2002/2003. B.O.S.M 2003.FURSWB#1 KotL..YTC449 PM#7 ..
Hmmm.. if you're going to get fussy - weight is a force.. surely you meant forces and not weights... =) Anyway - the formula is Force = ma = mrww - where m is the mass, r is the radius, and w is the angular velocity (2 x pi x frequency). Just get everything into SI units and you're sorted. Euain
