As you can see this cylinder has had the exhaust port timing split.
180 and 182 degrees.

So again, other then a clean up, a slightly higher port time on half the exhaust bridge, and a little higher intake timing, what are you getting?

So far my conclusions are, buy a Dremel with some bits and do it yourself.
I don't see anything special or specifically hard to duplicate here.
Just my two cents worth...
If bikes are for kids I'll never grow up.

Further thoughts on this...
I am by no means an expert as some of you are.
Perhaps I am missing something crucial.
But I can measure and run a degree wheel with my glasses on :geek:
Based on what I see I'd try it myself.
I am highly interested in any thoughts you might have...
