I modded the stock end cap today. I enlarged the opening just a little.
I have 2 650s , one with the Akrapovic an other stock exhaust.
It feels like the Akra give me at least a few HP more and the stocker feels
a little restrictive compared.
So I wanted to give the stock exhaust a little more pop, but at the same time not destroy
it or alter it to much an mess up the jetting.
So I used a carbide burr and burred out the opening until the sleve seperated, then remove it.
I then cleaned up the opening some so it looks about the same. I left all the spark arrestor stuff
inside the exhaust. The opening is slightly bigger now but seems to add throttle response without being
too loud. I will test it soon.
I think it will work out great because of it just being slightly altered.
