All
Frank, the guy that makes performance 2-stroke pipes, is shutting up shop. He has some sets of Nikon pipes left and you should be able to argue the toss with him to get them for £250-£300 a set. They are all hand made and follow the JHA pattern for the side-by-sides and the same pattern as the Tyga pipes for GP style. Use for MC21 or MC28 (MC21 dyno shows 5hp increase; need to run 135 mains) Go to www.nikonpipes.co.uk to see for yourself
