The Whistling Wanker is back!!!!

Of any value for a 350 SuperHawk with a 5 speed? Not that I've been having any problems!

From following your posts it sounds like your mechanic built you a really nice, tight engine Vince and I doubt if you need any extra venting.

Yes, I think I've thoroughly mucked with the engine, so I should probably now leave it alone!

But if someone were to mount this on their bike's engine, would they not need two of them? One for each cylinder?

Both sides of the head vent to each other so one Wanker is enough (don't get me started!).
I guess two would look more balanced but there would be a disturbance in the universe if you put any of those things on your engine.
If you decide you have to have some extra venting, there's better and less expensive ways to do it.

brewsky is right, there is a hole drilled in the side of the cap as shown in the picture.
