Yea man it sounds sick, I can't believe the difference it made. I def gotta figure out what jetting to get, I might just let my local shop do the work on it.i think i am running a 155 main jet for my HMF and CFM box w UNI filter. you may not have the same jetting though since your sucking way more air with that.
btw, that HMF looks great. i bet it sounds good too don't it?
