I've been putting octane boost in with every tank for a few weeks now, and just wanted to report the increase in smooth running operation, drastically reduced knock at low RPM (to the point I would nearly call it non-existent), and much better response when hitting the throttle after deceleration down to about 2-3k RPM.

I found you need to use Octane Boosters that use MMT(methylcyclopentadienyl manganese tricarbonyl). I personally like "The Outlaw" because it comes in four 3.5 oz bottles, and I use half of one bottle for each tank. The instructions say I could use less since one bottle can supposedly do 20 gallons, but I'm not convinced because I notice at the end of the tank the bike doesn't run as good as when it's full.

I pay something like $11-$12 for four 3.5 oz bottles, so that translates to about $1.50/tank. I stock-up at Auto Zone and carry a few bottles with me at all times.

I'm not looking for a debate about this subject, but I figure there might be a few who haven't thought about octane boosters, or have tried them and didn't use MMT's and found them less than inspiring for the added cost.

Take care! Happy new YEAR!

What octane is normal in the US?
In the UK we have 95, 97 and now 99 if you want to pay it

Mainland Europe starts at 93 which I avoided as I noticed the bike didnt feel right

I think you guys figure octane ratings different then we do.

The best I can get at a pump is 93 Sunoco. With the damn dreaded Ethanol warning.

Sure is right;
FYI
"In most countries (including all of Europe and Australia) the "headline" octane that would be shown on the pump is the RON, but in the United States, Canada and some other countries the headline number is the average of the RON and the MON, sometimes called the Anti-Knock Index (AKI), Road Octane Number (RdON), Pump Octane Number (PON), or (R+M)/2. Because of the 8 to 10 point difference noted above, this means that the octane in the United States will be about 4 to 5 points lower than the same fuel elsewhere: 87 octane fuel, the "regular" gasoline in the US and Canada, would be 91-92 in Europe. However most European pumps deliver 95 (RON) as "regular", equivalent to 90-91 US (R+M)/2, and even deliver 98 (RON) or 100 (RON)."
