i took the sled into the shop yesterday to tinker with the clutches and give everything the once over. when i fired the sled up the a/f is stuck at 14.7. i could tell it was doing it's usual start up with running lean in the beginning then running rich and settling back at idle(which was 12.3). when i move the sled around in the yard you could tell the machines running fine.
anyone else ever have this problem? i tried disconnecting the gauge, still goes to 14.7 when i turn it back on. royals having a 25% off sale and i think i'm going to buy a koso a/f,boost and temp gauge.
 
Your O2 sensor is probably done they dont last to long with race gas, just replace it and you should be good.
 
thx ernie, boy they don't last long? i installed new one the beginning of march last yr and i've only had the sled out a couple of times. i even bought the better sensor as well becuase of the leaded race gas.
 
Nope they don't last. I'm on my 3rd in 4 seasons and just yesterday same thing as yours 14.7. So looks like it's about 1 a season or every 1000 miles
