bike carbs are alot more accurate in they way they deliver fuel/air mix, so this means you have a bit more power, but also mean better fuel ecconomy cause its more efficent,
the small tubes on the under side are vacum take offs, originally i was going to join them up and connect them to the dissy but reaserch made me change my mind, one of the is needed for the brake servo vac pipe, the other 3 are blocked off
the guy that did my maifold has stoped trading, i paid the money cause its stainless, and the carbs are spaced to the head, meaning each inlet tube is the same length,
its fairly simple to do, but i would advise the megajolt route for ignition to get the best from the carbs,
my car isnt on the road yet, so only done quick trips around the block with the carbs, but it feels good, cant wait for the rr session to get set up properly,
spec of my engine is 1.6 pinto, with 2.0 cam, ported head, full cci exhaust, mj ignition system (soon to be modified mj set up), 36mm mikuni bike carbs and x4 k&n style filters)
