My dormant shadow was revived this morning after a the addition of new fluids and the priming of the oilways. The bike started and ran after the third kick, although the rear exhaust was heavily blued after a short spin around the block. The carbs have been bored true and new 3 1/2 slides machined to match by amalsleeve in the U.S. the fuel tank has been sealed and all components cleaned and re-cleaned. Points ,plugs and valves have been adjusted. I am new to the world of the Vincent and although I am somewhat mechanically inclined, I am looking to those of you with the experience of many years wrenching vincents to provide some opinion as to the possible problem. The carbs have been adjusted to the initial specs included in the handbook. The rear carb seems to pulsate air in and out of the velocity stack while the front does not as well the rear does not like to come off the air slide as readily as the front. Any help greatly appreciated.
