Good to hear back from you on this. I would also forward the idea that with the header on there, you should be careful to have small diameter piping on the rest of the exhaust, and not to have a low-restriction muffler. It seemed counter-intuitive at first, but experience proved that these engines do indeed like back pressure to develop decent torque.

And I do know what you mean about that rear cam plug. The one they say will fit often isn't the right one included. Which one did yours take, the plain rubber one or the one with the metal edge that you have to tap in?

Enjoy!
