Sooooo...this all means I should buy one with the holes in the side to stick my orange screw stick thingy in to make adjustments on my own? :D

No.

Motul is some thick stuff, & with Extra the heat & added timing, it doesn’t do well @ 32:1.

I’ve had a few. None of them were troublesome for me. Having said that, they all incorporate a rev limiter in the ignition coil. Piss reving tells you nothing. That makes them a bit mysterious in my book. I have always been amazed by what a RCH will do on an H screw, so it is hard to believe what a robot solenoid can be that precise. Maybe it isn’t? No way to tell with the rev limiter kicking in...

I think if I remember correctly my MOFO 261cm V1 was a .22 squish. I have been running an oil cocktail of 32:1 since I got it from Al. I have not experienced any of these running issues at all.
My plug looked brand new, lightly golden brown.
Maybe I should consider myself lucky???

I run 16" 3/8 full chisel or 18" 325 full chisel with this 261.

Many oils involved. LOL
RA, VP, Klotz Benol, and a few others.
RA at 50:1, then the others to get down to 32:1. Running 92 EFree fuel from NY.
Gotta have the Klotz for the smell value.
