New Racing Mower Test - Exhaust Burn in John Deere L120
Checking to see if our exhaust flow/temp calculations were correct, we were almost dead-on......the burn ends 1/3 into the scoop. This new build's class requires a stock engine(CP-R/Mod-X-R). Seems to run just pinch lean. WIll take care of that right away. Sounds nice and hearty, with no annoying short pipe raspy/harsh crap. Took it out for it's first run......OMG.....fast........
