I got one homebuilt and I had planned a dyno run before the season ended
but between buying a house and unstable weather I did get to it.
It will be done first thing in the season of 2005.
I really needs some tuning (more petrol) in the low and mid RPM ranges,
in high RPMs in works OK with a open-filter/mistrals map I got on the net.
I gutted a stock crossover removing some mesh, damping and a stabilizing
bolt. Cut of the left hand outlet, banged it together and welded it shut.
On the right side and put a 2" bend and a 4" Supertrapp megaphone with
6 diffusion plates.
The sound is nice, classic looks and save a few kilos weight.
