Rather than have many individual posts on one thread, can they all be put into one list???
A few to add to that list would be.
http://www.jacexhausts.co.uk/index.html They did the exhaust system on Matt's bike.

http://www.carrotcycles.co.uk/ Converted 748/916 throttle and cable to be used on a 583.
