I am just getting ready to install their 5,000+ head and just looking for some opinions on the head. I ride down in Fairview, UT the most and curious what fuel you guys recommend. Any other opinions on it are definitely appreciated. Thanks guys

I have the SLP stage 3 on my 11 800-163 RMK and use 91 non-eth with no problems as long as you keep a clean fuel filter in it, as i discovered, it would go lean and DET if the filter gets dirty! I ride above 8000 all the time and have a PCV with enhanced fuel map +2 to+5 % and timing remains the same as stock!

I don't have the Slp head but I have the par 13.6:1 on mine. When I only had the head and everything else was stock I ran 92 octane pump gas with 20 percent avgas. I ride 4 to 6k feet.

Thanks for the info. I have the gaskets coming tomorrow to button it back up so we will see what fuel it likes.

I will definitely just try 91 pump for sure and see if it throws some det.
