Re: MX50 cam in a SS?

Yes, there's no point in having loads of valve overlap and stuffing the whole system up with a restrictive exhaust (or a restrictive air filter). Dumping the stock silencer and re-jetting the carb to suit a straight through system will liberate a surprising amount of power even with the standard cam.

Re: Interesting intake guide Idea.

Seems like an excellent idea - better than using rubber seals because it encourage oil down the guide rather than limiting it, as a seal risks doing.

Re: Rear Pedal Brake Switch and Pivot

If it helps, the switch is identical to the switch used on all Triumph twins and triples from 1971 up to when they stopped making them. Shouldn't cost more than about £6, whatever that is in dollars (about $6.50 these days I expect!)

And if the former, would it stand to reason th...
