I been reading Groups K 750 page for many years and done some of the mods on it. I'm going to have my cylinder head ported around November time frame. Probably the busiest time of the year for them? Anyways are there different levels of porting for my requirements? The website mentioned "Porting stages are A) Sleeper, B) Hammer 92 octane, & C) Hammer 105 octane".
Well my engine is the big pin 750 Zxi. I already run octane 93 on my 180cc compression head, exhaust pipe, flame arrestor, Skat Trak 14/19 swirl, and other mods. So, "B" option for the porting be good? Or is the porting the same between them all?
I don't see the hammer 92 for the Zxi, so is the option not available then? My goal is to pick up top end. My low end acceleration is very good.
Regards
