Problem I see is that the displacement increase is marginal so difficult to imagine that it will affect flow rate significantly. I wonder if the claimed (I accept that the claims are likely correct but that doesn't validate the claim) power increase due to the displacement increase may be as much or more due to the increased compression ratio? At this stage of life I'm not going to build another flow bench and not prepared to spend money on dyno time so will have to keep the popcorn ready for those who can/will. These are very interesting subjects but extremely difficult to arrive at conclusions without empirical data from KLR. I've seen the practice of extrapolating from one engine another come up wrong too many times to assume. Perhaps, were someone else interested in this who was close by, the interest might drive action. I've invited Paul to drop over after work but he continues to scorn my invitation. Has anyone evaluated the effects of simply raising KLR compression by piston or gasket change?
