O.K. Ive been using mostly B.P. or Marathon gas because thats about all thats around here. Never had a problem with the gas. About 6 weeks ago I filled up with Shell.. 4.5 gals.... Within 10 miles the bike started running bad.

The more I drove the worse it got. After I ran about 120 miles, I drained what was left into my gas can at home, and filled with marathon. 10 miles or so down the road she came back to life, now.... I havent touched shell gas since. Monday, 6 weeks later I was ridin with a friend in some new territory, we both needed gas, I was already on reserve. Whats the only thing we found?.... Shell.

So I just figured go ahead and fill it, the last time it most have been a bad batch of gas. WRONG, after I went about 20 miles towards the house, she started poppin thru the
carb..(which she never does).. and losing power. Reminded me of the old
SVS days.

I had to go 120 miles home and man did she run like crap.

Update: Drained it again yesterday, got a couple gallons out, filled with marathon again, ran the heck out of it today, and shes back to her old self! All of this done without additives just to make sure it was the gas. Question, anybody else have this problem with Shell?? I thought it was good gas...cleaner valve adds and all. B.T.W. It was 2 different shell's, 100 miles apart.
