I have 125 miles on my new 07 NE5. Sometimes I turn the 'run / stop' switch to stop when I need to slow down instead of riding the brakes. I also figured out that if I hold the compressino release and give about 1/2 throttle it pops real loud and blows flames out the pipe. Will this hurt anything other than my relationship with the neighbors? Could this poping cause oil leaks in the engine?
