I normally buy a jug of VP110 to mix with non-ethanol pump gas for my modified bike. Went to the local bike shop and they didn't have any more but they had VP2+. The label says for 2 strokes and comes with oil mixed at 40:1, 105 octane, 5.9% oxygen enriched. I thought let's try this stuff straight up with a little Yamalube 2R to get the ratio at 25:1. I kick it, with the chokes on, and it starts right up and then stalls. Odd, but it has done that before, it floods. Take the chokes off, crack the throttle open, kick, vrooom, it's ready to ride. Off I go and notice it is running as smooth as can be. Get to the back roads and start to give it some juice, oh yeah, seems like more power. It never skipped a beat on a 25 mile ride and the cylinder head temps were lower than most of what I see, 285f max. On the way back I wacked it through the lower gears a few times and it does have more punch. It wants to go to 10K but I keep it at 9.5. After hitting that turkey, I got a little wimpy about the back road through the woods high speed stuff. The rest of the jug will be mixed 50:50 with pump gas with oil at 25:1. I like this bike (RD400) better than my RZ because it is more stable, corners better, stops way better, and will probably walk away from the RZ in a straight line. Thanks to John Ritter for working my cylinders, heads, and reeds, this thing runs perfect.
