Just read through this: http://www.suzukiquadracerhq.com/lt250/piston-died/msg51594/?topicseen#new
That was my experience with running pump gas on the ole two stroker.

Since my 4 strokes are not super built they run fine on 93 pump without any problems so long as I drain them when they are not being used. With that said, my LT also is not super built.

Keep this in mind, when you mix your gas with oil you actually loose octane, that with the detonation protection that the 110 provides and the longer plug life, I believe that it is the better choice.  Just my  from experience.
