Great read...(I own a highly modified 2000 YZ 250)...
If your bike is jetted corectly (2stroke) it will run great on VP C12....It is one of the best overall fuels for all riding/racing.The engine will be crisp and clean!...There are other great fuels but are cost limiting to me!
The advantage with quality race fuel is that it is a consistent burn.Since my compression has been changed my YZ will not run on pump fuel anyway,but I would not run straight pump fuel in any stock 2 stroke racing bike...I would at least mix it 50/50 with a quality race fuel like VP C12.
Yamahas YZ's come jetted very close to perfect and reg fuel will sometimes be very bad to use under high load circumstances... and cause detonation probs..
Pump gas these days is pretty junky stuff and not what I would use (without mixing) in any 2 stroke racer (if riding agressively especially).. AND.. Keep the fuel out of the SUN!!
Now 4-strokes are a whole different story!....Yikes!
