If it's a twin then is should be in theory have a better spread of torque through the rev's than a single.
Quick update, im painting the wheels glossy black (Hammerite) and thinking of doing the same with the exhaust but leaving the chrome panels on the actual exhaust part. If not im definitely doing the back side of it (what you dont see) and the parts under the panels... i'll do a quick pic to show what i mean.
Hammerite wont take the heat .. And doing the wheels will look crap . Are you going for the rat bike look ?
