Plan is to keep it as a work saw, just more power in that rpm range, exh dur is short, pipe calc'd at 10k, haven't tached it in the cut, but definitely more power and holding more rpm.
Pulls the 404 full chisel harder than the 3/8 semi I had on there on muffler.
Love my bikes, feels just like a 2 stroke bike to use (engine wise) snappy, can feel it get 'on the pipe'
