Does anyone have single/dual plug comparison dyno charts to post up? Over on the Norton Commando forum there is a guy who has posted up lots of head flow charts...seeing is believing.
Some interesting results on port sizes, lie the standard head flows better than the factory ported one
I twin plugged an R100 20 years ago,as was the fashion but I think it was the lighter flywheel and 40 mm carbs that made it go well,
