Is 110 Octane fuel safe to run in S&S Stock 117 Motor

Isn't that how it usually goes? The people that make the motor recommend that you use a certain fuel or other product in their motor, and somebody knows more than the manufacturer. I'll just stick to what the maker says, they've been around a whole lot more of these motors than I have. That being said, it's your bike, do what you want to it. Stay safe

Never heard of such a thing............. :rolleyes: :(
Explain how that can happen. :confused:

I laughed when I read that also John:oldhardlaugh:.........I have ran multiple tanks full of gas that were 115 Octane Leaded Sunoco Race fuel blended with with 92 octane pump gas threw my bike and NEVER had a problem...EVER:cheers:..........Of course my bikes timing,carbueration,and intake and exhaust are tuned perfectly....SO I have no pinging issues like your having...I would suggest you get your bike tuned properly like Curtis suggested....then try a blend of fuel like a 50/50 ratio if ya want......The higher the Octane number,the MORE compression the fuel can withstand before it detonates bro.....get your bike tuned properly,then play with fuel blends if you want.....99% of the time I just run Hi-Octane pump gas.....I was just experimenting with all this damn racing fuel I got in my shop...:chopper::chopper:

WAIT A MINUTE!! avgas does NOT absorb"water" any moron who doesn't check for moisture in his tanks
is a bigger fool then anyone I know. It's called "condensation".... look it up before you give some BS
from who knows who or another forum.

BIgDog rider, mechanic and, x-PILOT ...... yes as in aircraft..... Quad by pass killed the pilot hood
in the sense of atmospheric air, condensation is the liquid form of "water" vapor. therefore, it is WATER :2cents:

For WOT its worth:
Yeah, and that's how you ride it. No instant WOT, no lug up a hill in high gear. I bought a cheap rope scope, shoved it down the spark plug hole, found a perfect V that sat smack dab in the center of the piston and spark plug hole. That was a perfect machined hole, a spark electrode sitting real close to that V.

I ran up a steep incline and heard some nasty noises. I pulled the plug again, found the V no longer. It was now like a crater and inside that crater were small tiny molten aluminum balls sitting in there = Detonation Deluxe. I run regular in a 12:1 rated top end. You'll create the same effect of messing with the penultimate number about to intersect in a most electrical (I think) way is Kinetic vs. Throttle open entry of the Penultimate.

So as I understand it in my world, right before the intake closes, who zero's out in the chamber is 14.7 is the constant. Only thing you changed was upsetting the 'Balance.' And in Ohm's world, there is a formula of balanced electricity that can be measured. Without magnetism = No Spark.

Costco vs. Shell:
Where is there HP gain in a 4-storke? The head. Why is there gain? The curve causes friction so you angle the port as straight as as you can. Where are we going withis? I can see all the way down to my intake port. I ran costco gas and the carbon build was backwashing on the carb side of the intake valve. I switched to Shell and the chemicals they use for carbon cleaning is chemistry in action. I could see the valve again, not carbon.

And what happens when that carbon keeps building up on that valve??

Weight = The less weight at the valve-train area the faster the spin up. This adds two variables to it.
Drag = Now the air has to climb over a rough area rather than a smoother valve surface.
Carbon = Acts as a sponge. Fuel is absorbed and initially goes slightly lean say; once the gas evaps.
FEReaction = The opposite reaction is that she is now absorbed like a tampon, rich goes the flow. That gas puddle is sitting at an angle as if drained at a 45° so it enters first.
Rich = As if to make a case for air being taken up in that port per square inch of air lost so rich as if that carbon build is air lost at the port and that initial volume is the constant balance = Whoever enters first: is why the AFR changes you go jetting things like faster air moving out the louder performance pipe anshit.

Water cooled GL1000 Hondas were notorious for head gasket failures. The oil would turn milk chocolate in color. So the steam would clean the valves/piston dome/cylinder chamber; as if you were looking at brand new parts out of a box. Thus, a water injection setup you stick with costco gas (hand over moutHa-Ha icon).

This shit is making me laugh so hard I'm falling off the couch !!!
FWIW, Costco like Hess, and a bunch of others buys "spot gas". You never know what you're getting. Could be Shell, Texaco. Mobil, etc.

FWIW, I can only go buy WOT I've experienced. Unless you follow an independent tanker, leave Shell/Tex/Exxon's depot stations, who knows where those tanks go in between point A and B, with an 'alleged' siphoned off, add who knows what happens, etc. Unless you can explain the simple junk science you can laugh at it all you want.

It's all about chemistry. If you do not believe in chemistry, you do not believe in heat or magnetism. More junk science to ponder.

I believe in water! Went to a Chevron station down the road from my house after a tanker pumped gas in the stations tank and got a bunch of water. My bike fell flat on its ass and I had to drain the tank and carb bowl to get that crapola out of the bike. Never the less that was the last time I go to that station. Been going to the station down the road that sells non-ethanol gas. No issues from them thus far...

I did notice, and it seems odd to me, that the outside intake valves (#1 LHS and #4 RHS) have some carbon deposits on them. All the others are clean. Just kind of weird IMO...
I just came across this. Inline 4 motorcycle engine. Can you explain it, John? I'm at the couch, ready and waiting.

Can be the valve seals, can be the tune up, can be the fact that the outside cylinders run cooler.
We run our race motors with a computer that gives us unlimited feed back. In- line motors, unless compensated for , normally the outside cylinders run cooler.
Please DON'T try to tell me about this SHIT. we have 4 Pro-Mod championships( # 1 plates). Didn't get them by being nieve or stupid.
