I have had quite a few 2 stroke bikes but am not a 2 stroke tuning specialist. I'd like to hear some more explanation/thoughts on this as I have experienced some odd 2 stroke tune/plug issues particularly with an ex race Yamaha RZ500 V4 2 stroke that i had bought years back and never thought about since till i just read this.nitro2 wrote: ↑Wed Nov 07, 2018 11:34 pmNot that kind of failure.MadBill wrote: ↑Wed Nov 07, 2018 2:47 pmOne could see how this might happen with pre-mix: closed throttle = no air = no fuel = no lube... Not with oil injection of course.nitro2 wrote: ↑Wed Nov 07, 2018 11:14 am...Also in some other types of racing, such as 2 stroke marine racing, there can be weird on/off throttle scenarios that cause engine failure in a race, but there is seemingly no way to duplicate it on the dyno (the engine on/off throttle scenario can be duplicated, but not the failure).
Detonation failure. Closing/closed throttle 2 stroke detonation. This type of detonation is common, even on mundane stuff, but on higher powered applications is more intense. "Detonation" is a bit generic, can be HCCI. Generally very brief, but it doesn't take much to cause damage on a 2 stroke. Opening the throttle at just the wrong time after closing it can be worse yet.

Well it's interesting to discuss, but getting pretty far off topic here, so probably something best left for another day, another thread, unless REC starts running 2 strokes
