Regular gas. No choice
While on vacation I ran into an almost out of fuel situation and wierd as it seems, the station I had to use only had regular 87 gas. I took on fuel there and ran about 100 miles before I could top up with 91. What is the reason for using 91 and what damage is done by using regular 87 octane..

No damage really. The higher the octane, the easier it can withstand temperature and compression w/ out igniting and causing preignition and detonation. This can also help lead to an engine running cooler.

UR ok. i'm glad i didn't have to do that. i have tried running mid grade in my 2001 RK FLHPI which has higher compression than the standard 2001s and newer Twin Cams and it ran like crap and pinged under load. 2001 i think was the last year the cop engines had higher compression about .5 differenece.

91 Octane is hard to find in Bossier City, La. Usually you have to go with 93. I filled my 2006 Street Glide EFI up with 93 yesterday and after a few miles I stopped at the store. I started the bike and after a while I noticed the engine light was on. It went off after a few seconds. Never saw this before. The bike only has about 500 miles on it. Any reason to be concerned or should I go in to see my dealer?

Suburban,
I live in West Monroe, La. and use 93 all the time and never saw a light on my '06 RK. Hopefully it was just a little glitch that corrected itself. Never hurts to check on it w/ dealer since bike is still under warranty IMO. Ride Safe!

Sounds like tis not a problem but my best friend rides a 2000Heritage and I've been with him twice when he has put 87 in it by mistake. His runs like crap with it..it pings and knocks real bad.
