I have just completed my rebuild and it is now sporting a set of Jemco expansion chambers. I have put my custom old school rear sets and they are just horrible, they don't work, cannot be adjusted and also bend out of place. At present they do not work, cannot get the bike into first...or change down reliably, bad, bad, bad!

I am hoping to ride this bike to France for wheels and waves (this Sunday) and need some advice/recommendations on what aftermarket rear sets would fit my bike....I need to order something tomorrow.
Your suggestions would be greatly appreciated!
