FUEL QUESTION
« on: September 07, 2013, 04:14:31 PM »

I have an 77 CB750k. Do I need to concern myself with Ethanol in my fuel? I usually purchase 100% gasoline but the only station in my area that has it has let me down. I filled up the other day and suddenly couldn't get the bike over 60. It just wouldn't go any faster. I drained it went and got some other fuel (with Ethanol) and it runs fine now.

This has been debated over and over. Getting popcorn, here we go again!

But we were boys, and boys will be boys, and so they will. To us, everything was dangerous, but what of that? Had we not been made to live forever?

There have been a lot of threads. No one has reported any damage that I know of. That does not mean issues will not show up in the future. Most people use Regular.

I've had problems with failing o-rings in the carb fuel connector tubes, requiring two carb rack disassemblies in one season. I have changed to non-ethanol fuel (Shell premium, the only one available here except for $$$$ racing fuel) and haven't had any problems since. I can't claim it's definitely the ethanol, but these seals were problem free for decades before 10% ethanol was introduced. The o-rings were all replaced with Honda OEM parts about 5 years ago.
