Hi guys, can someone tell me what, if any, is the advantage of running 45mm carbs over 40s, if the venturi is only 32mm? I've changed to 45s, but am wondering whether it's really better than just getting new chokes and jets for the 40s?
And where can I get a good dyno tune in the NI and how much should I expect to pay?
And on another note, what size exhaust do people run? Mine has always been 2", is this big enough? Engine is 1570cc A15, 11.75:1, ported head with std valves, kelford cam can't remember specs but works between 4&8000rpm, 45s, coby extractors.
Cheers fellas
