thoughts on octane booster?

[wymple]

I get less ping in hot weather with 87 octane ethanol than with 89 octane regular. Ethanol helps, not hinders. It's why my son uses alcohol in his super modified pulling tractors, way more compression ratio than he gets with gas. I use 91 octane whenever I can, but a lot of stations here don't carry it.

Use non-oxygenated fuel( no corn squeezing's) With a stock motor you will be fine.

Very hard to find.

Thought i read in a manual the recommended rating is 90 for our GSs. I run the 87 and havent heard any engine pining.

Mine says 87 or higher as needed.

Depends on the amount of ethanol used. 85% would be a cold dense fuel charge which equal to higher horse power ratings though less mileage.

There are 3 things never to argue about. Politics, religion and ethanol with a resident from Iowa. I will not dispute your reply, as I have no evidence to dispute it. On the other hand, All bikes from the 80's were jetted to run on non-oxygenated fuel. They were lean from the factory to meet emission standards. I was in the biz for 20 years and seen the dyno runs. Alcohol takes the place of fuel which makes them run even leaner. You can jet around this and get the bike back to "normal" which is better than the original factory settings. Doing nothing? Sure it runs, and it may run fine to most people, but they can run much better. Its getting easier to find non oxy fuel in my area due to the influence of hot rods, classic cars and boats. I have a close friend who is a boat Mech. He makes a LOT of $$$ off of people who use oxy fuel in there boats.
