which octane gas do you put?

Thx, but Ill stick with KNOWN results , your not the first to doubt, its cool!

But I wouldnt waste my time and money with it, if I didnt see the results, and thats the simple truth , it too much trouble otherwise.


I once had a bike that had carbon buildup up in the exhaust a screen required to be cleaned every 11k , ran half a tank of leaded race fuel, under the lead oxide powder was shiny clean metal. That screen completely decarboned

Which on the shelf snake oil will do that?

Yes...argue with a racer.....(Lewd)

leaded race fuel is for tards who want to waste fuel and foul plugs

Plugs hell. You should have seen the build up from running 93 without the tune for it on the back of my valves. There was some seriously crusty shit going on back there....the pistons weren't looking to hot either.

About 6 tanks of FI cleaner later they were all pretty again.

Luckily the Triple has no emissisions shit on it.

Tards and fouled plugs?

Lets clarify for the inexperienced,

out of the few hundred thousand miles on a leaded diet , I've had zero plug issues as a result of leaded fuel race fuel. Quite the opposite

Those that have issue with fouling plugs, are running fully undiluted on bike that isnt jetted for the fuel or cant use the octane level

My use for the lead is quite different, its only a supplement for decarbonization and upper cylinder lube, and it relatively small quantiy per tank.

Bashing something one has zero long term experience with , is much more retarded than a 25 cent cup of leaded race fuel as a supplemental diet.

I get a kick out of these threads though , you talk great, but you know nothing.

I haven't had a fouled plug since 1988. No races gas needed.

Also, no need for additives.

Ran most of my race bikes on pump fuel. Ran all of my street bikes on pump fuel.

Was it magic?

Plus, new bikes don't foul plugs like old bike did.

And you shouldnt, Spark plug fouling has nothing to do with the leaded diet I run, nor creates it. But spark plus do recieve geogous decarbonization with my diet.

You are right though , you can run straight pump and have long life, I've not said you cant and most routine cases I have to go several tanks without my diet till I get back to the garage. I run the leaded race diet cause I see the benefits with emaculate decarbonization, and less valve recession.

really it only takes a couple cups,every other tank, to maintain and recieve the benefits.

I dont have to run it, like you, but I do , it acually runs me around $55 for five gal and lasts about 6 month, or 16 cups per gallon.

In my racing days , I never saw much value in racefuel either as far as performance on a stock bike. If id ran it long enough however, I may have noted, the beneficial power valve and exhaust decarbonization, which would have been a benefit.

Only when I started pressing solely on the street, in trying to prevent valve recession in small motors, did I dicovered these key side benefits.

Sorry to create all the conflict, your avenue and mine are different, but altleast we share for alittle amusement.

That's a negatory that I said that. I see benefit in racing fuel and ran it during my race days.

My NOT seeing a benefit in race fuel on the street is directly related to a friend who builds motors for a living. He has won AMA nationals. He did my 675 and we had 2 tunes for it. Street and race. Street made 121RWHP and Race made 125RWHP.

Well that was pretty stupid wasn't it? But you corrected it properly. There is not universal octane for bikes just like there isn't for cars. You just go by what the manual says.

Lewd,

I have a motor tuner friend also, and he only runs leaded race fuel on all his bikes, street or otherwise, also dumps the $15 oil after every ride. Which I think is a little nuts on the expense. But he isnt riding all the time either.

Was your set up between pump and racefuel ?
seems like a 3% difference on performance

All this talk about CR and nobody mentions flame path. Motorcycles have relatively small cylinder bores (usually less than 100mm) and modern, more efficient combustion chambers compared to cars. The flame path is generally much shorter than car engines.

AMA Superbikes and FX machines were running CR above 14.5:1 and guess what octane they were running...

VP MR9 fuel used until 2005 is about 87+93/2 = 90 octane.
VP MR11 fuel used up thru 2008 is about 90+96/2 = 92 octane.
Both contained lead.

Sunoco 260 GTX currently used in AMA Superbike is 98 octane, unleaded. Probably higher than needed, 260 GTX was an off the shelf unleaded racing fuel not specifically developed for Superbike engines. In fact, 260 GTX was developed for NASCAR engines in 2006. Thank Roger Edmondson for that little tie in. Betcha didn't know that!!!

I knew they did away with the lead, still havent heard the real scoop on whether its been a positive or not for the motors.

I've seen nothing posted related to it anyway

The bike was an AMA FX spec bike. 3% makes a difference at that level.
