Yeah, 9:1 is low compression for a v twin as far as I know. My friends Night Rod runs 12.5:1 from the factory (If I remember correctly).

I bought my friend Mike a 5 gallon drum of Toulene for his B-Day. It was expensive at around $65. But you can't just add the toulene to your gas tank, it needs to be mixed with a few other things like ATF.

But I doubt that low octane is your problem. My first guess would be that using sh*tty gas clogged up your carb. Arco will cause the main jet to get clogged up with calcium deposits. And the octane booster (which is also used as a fuel injector cleaner) cleaned out your carb. Next time it runs rough, pull the bowl off your carb and brake clean the crap out of it, especially the main jet. See if it makes a difference.
