[updated:LAST EDITED ON 04-Jan-03 AT 06:36 PM (EST)]I guess I remember trying that.
The exhaust valve diameter had a bigger effect with desktop dyno.
But then I pushed the model and tried 3 inch exhaust valves.
And that had huge improvements. Then I concluded that the model may have bugs in that area.
Maybe I was wrong to conclude that.
