83 GPz1100 Unitrack, fuelled up with bp98 as an experiment, I was avey surprised to notice a significant difference in smoothness and response, I am very impressed. But I am confused. The motor is hardly specced to run such a high octane, 2v fuel injected air cooled 8.7-1 compression, so hardly a high state of tune, but the difference between 91 and 98 is instantly obvious. Why?
Why does my bike go better on 98?
