So a couple, weeks ago I put an air fuel Guage on my 2015 INDY 800 on the stock pipe. It has V-Force3R reeds. I wanted to see the midrange Air Fuel ratio because my wife will be driving this sled a lot as I sold her 600.
I don't know why these engines haven't been going down because it was SCARY!
From 5000-6300 I seen 13:2 up to 14:1 and I guesstimate it was at 20% throttle.
Wide open at 8000 RPMs it was pig rich... 11:8-12:2.
I added 7% in the mid range and took away 3% on top. Brought the numbers down but needs more tuning.
Just figured I would let y'all know to be aware of this problem!
