Handle bar weights

My Handle bar weight is damaged, an ideas where I can get replacements?
Where would I find a suzuki part number?
Also Headlight cowl damaged OMFG £110 for a replacement.

My apologies for not seeing this post before now Steve, the part number you require is 56200-10890. Just pop into your local dealer and give them that number and they will order it for you, might be better than sources it yourself, it will cost you about £40, they are also known as balancers.
Hope this has helped.  

Many thanks, I have now lined some up, again these are quite pricey at £46.00 I had forgotten how expensive Japenese spares were, in the early seventies I remember a honda indicator set was 25% of my weekly wage.
