Spud, when you find the tape measure can you let me know if you think it's a goer. Was just looking at various clamps on fleebay and the Katoom ones looked about right.
Just bought a 240 and from various sources can assume that fitting a 200 top yoke (if you can find one) is a vast improvement. Has anyone tried modifying the original 240 yoke by machining off the handlebar mounts and replacing them with a modern MX type handlebar clamp? KTM type looks as if it might do the job. Not too sure what effect drilling two more holes in the yoke would have on its long term durability and my own well being!
