Strangely enough this cylinder will be quite low revs as it is, probably 11k with the right pipe. Durations are quite low with a low blowdown figure so will make good torque. I ran this shape exhaust port on the Notso Special and it was nice to ride with a really good power spread but really came alive when it hit the powerband.There is scope to increase the exhaust duration by another 10 or more degrees but the rider is heavy and we want it to pull well, so will try it and see and maybe lift the port more later.
We may try it with a Homoet pipe and see, should be ok with such a low exhaust port.

Oke thanks, the exhaust duration is low indeed, but, like you said, you can make it higher for development.
but how width is the exaust port? You can make it very width in the shape you have make it, can't you?
