Started this as a new thread - following my issues with ignition and then finding a carb issue I'm looking at outing the twin 45's and replacing with a set of bike carbs. I think I much prefer a set of bike carbs as I've played with these a lot more, having run my 1800 Zetec lump on a set of GSXR600 carbs for years. Never went off the boil or needed fiddling with! So Has anybody any experience of Bike Carbs on a 2ltr Twincam -if so what carb set did you use and roughly what size main and pilots did you run? (Just gives me a starting point) Not sure if anyone supplies an inlet manifold as standard for one, if so that will dictate choice of carbs. Any tips gratefully received!!
