[QUOTE="Rich Rohrich, post: 1390016, member: 16241"] If you are tuned to the ragged edge running 50:1 at Road America on a TZ250 and dumped a 20:1 mix in the engine without a jetting adjustment you might (let me repeat that [b]MIGHT[/b] ) be able to lean it enough to cause some detonation and hurt the engine. On the average dirt bike there is no way in hell you'll ever manage it. Nice try though. ;) I've spent more time than most playing with jetting and oil ratios in two-strokes and I'm convinced most will never notice the fuel difference between 20:1 and 50:1 , but the engine especially the roller bearings will more than likely notice the oil difference. Whatever your personal thoughts are on oil ratios Bob probably brought up the most rational thought. Running more oil should make a hard to replace crank last longer. Good reason to tip the oil bottle a bit more. [/QUOTE]
