Thanks for that link. I've contacted them and received a quick reply saying they would get back to me with a price, including shipping, for sending one for my 1928 Ariel to the U.S.david.anderson wrote:I believe this link is what you are after. http://www.mdamotorcycleengineering.com.au/index.html
Accurately setting the timing is always a fiddly job because sprockets/gears almost invariably rotate on the taper just a little as the nut is tightened so I welcome the ability make any necessary small adjustment after the fact. Of course, being able to accurately set the timing to a fraction of a degree of any desired value begs the question of precisely what value to accurately set it to, but that's a different (but related) issue.
