font-family:Arial'>I normally agree with you guys on 2 stroke tuning, but as we
lengthen the pipe to get a smoother transition, what is really happening is you
are bringing the "resonance" rpm down and giving up top end power. If
you go to Ed Hartley's two stroke page, You will see that there is not a lot of
difference in rpm between the muffled OS1.40's and the tuned pipe ones. I agree
that if you have an engine ported for a pipe and all's you care about is top
end, a pipe makes a huge difference. But we care more about throttleability on
these engines, so the HP is down. I'll loan one of you guys my 590 and you
can test back to back if you want.</span></font></p>
