AFR gauge is a go. Took it for a drive, way too rich at idle in gear. Leaned it out, raised the idle back up a bit, much improved.

I’d gone to the silver step up springs quite a while back thinking it was running lean but I ended up putting the orange springs back in, and off idle is in the 13s though I’m finding that I need to give the gauge a little bit since the readings tend to lag a bit to find their nadir- I might have to lean out the jets a bit but now is much better.
Awesome, show a pic of where, how you mounted gauge.

Ended up grabbing some 2" Dom for the bull bar and some 1/4" 3x4 angle for the goose neck
