'Blaster 61X weak bottom end power after rebuild

I've got an update on this for everyone. I added a Tao Ceti flame arrestor and a Jet Works flow control valve and it really woke up the bottom end on my 'Blaster a lot. Now it pulls much better on the bottom end. I also turned my low speed screw out about half a turn.
I also got two more highly desireable performance items for it.....A Factory B Pipe with the Mod chamber and a Hooker 9/15 prop. I think this will really wake up the bottom end nicely. I'm going to set my Factory B Pipe up for dual cooling as well. They say the Mod chamber works well with ported, higher compression engines. I'm hoping that my mildly built 718 ported Jet Maniac cylinders along with the higher compression milled OEM Yamaha head should give me some punch down low, especially when I put the Hooker 9/15 prop on. Could anyone comment on this combination or something similar that you might have and what I can expect from it?

pipe and impeller will be the two biggest noticable changes. im not sure how much youll pick up with the factory pipe over the riva red pipe. both are good pipes. the mod chamber will pull a few more rpms since its a little shorter than the limited chamber.

I'm hoping the 9/15 Hooker that I'll be installing will give me a little more bottom end hit compared to the 10/16 Hooker that I currently have on there.
