nytro gems low elevation questions

[Aaron maheu]

I'm new to the 4 strokes so please bare with me. I installed a oem low elevation supercharger. Now on the gems box if I want lean out mid range do all I have to do is adjust the green blue mode down a few and richen up red mode. Or do I go straight to yellow mode and adjust from there. Right now idle is 12.5 mid is 10.1 and wot is 11.7. Seems rich . Also when I snap the throttle I get a lean spike and when I let of off it quick. Is that normal.?

I have problems with mine. I can max everything out and it runs 14.7 at idle and midrange. Drops to 13.3 at Wot

You will get spikes... Cruising at 10 AFR is fat as hell... 11.7 at WOT is not bad, be better to be at 12. Idle 13 to 14 is fine.

Whats each color mode on your Supercharger? It explains how and what each of them will do. Not sure if its the same as my Apex SC

I can only adjust 4 modes on mine. Green yellow red then green blue. Loops back around. I think I got it I'm waiting till I get a little more snow before I take it out. I had my track up in the air no load on the engine when I was adjusting it to which prob is not the right way with no load. I decreased green blue mode seem to bring up mid range 11.7 now idle is 13.7 14.0. Getting there. I hope.lol

I beleive green is like my pilot , yellow is my needle. Red is my main jet. Green blue is amount of feul the gems is telling the computer add to the sled or accelerate pump . Not sure

Not sure if this bulletin comes with the kit.
