Like others said, I cant see a tank of reg doing this..

 

Yep. What 81rat said

 

OP, A lesson in octane is in order. Higher octane gas isn't "cleaner". Higher octane gas won't make an engine that calls for 87 octane run better. 93 octane gas in an 87 octane engine won't "clean" your fuel injectors. Similarly, running 87 octane gas in a high compression engine that calls for 93 octane will not "gum up" the works.

The key word in the paragraph above is "compression". Octane is a fuel additive that helps prevent "detonation" or early ignition of the air fuel mixture during the compression stroke. When air is compressed it heats up. In a high compression engine, it can heat up enough to ignite. what happens is you get 2 flame fronts in the cylinder (one caused as planned by the spark plug sparking, and the other inappropriately caused by compression). This gives engine knock or pinging and can wreck the engine.

This is mitigated largely with fuel additives (octane boosting chemicals) that prevent the air/fuel mix from igniting due to compression.

So to the original question. 1 tank of regular gas isn't going to wreck the engine. It's not good for it, and don't make a habit out of it but it's not the cause of your troubles. It could have caused the overheating but likely one tank of it wouldn't do lasting damage. My guess though is that it's some other issue and not the gas at all.

The overheating sounds like a running lean issue. What's your intake and exhaust setup? What the bike tuned after (if) exhaust/intake were changed?

Secondly ethanol isn't the problem. In a lot of states, it's not even possible to buy ethanol free gas except at a marina or airfield. I like in MA, I think we might have 3 gas stations in the whole state with "real" gas. The politicians are in bed with the corn lobby and foisting this **** ethanol gas on us. Modern engine manufacturers including the MoCo know this and their engines can safely handle up to 15% ethanol.

Does your fuel pump sound normal when it primes? My guess would be some kind of fuel pump issue going on. Maybe dirty/partially clogged fuel filter.

 

Almost sounds like a fuel tank venting issue.

 

Ok after more disassembly of cover on top of tank. See my issues. Multiple. Pulled locking bar holding filter and there is sedment/sludge inside. Corrugated fuel line brittle/dry rotted snapped one that is straight tube to bottom. Rusty looking in many places because peeling paint/lining everywhere. I've only had bike in my possession since June 1st. Now I know where to start.

 

2010 bike with 220 miles on it... that's seven years of sitting. If it sat with ethanol gas in it then yea, it's eaten everything in there.

 

Sorry since 2014, 220 miles, actual odometer is like 16k-18k. I tried putting pic but it looked like posting the path and not the pic. But inside tank is layers and layers of paint chips/flakes. Replacement tank is ideal solution, but I could get by replacing dry rot lines, filter, plugs, o-rings, clean and scrape flaking paint. Later a more proper fix.

 

A new tank isn't worth it unless you can find a cheap take off on ebay.

The far cheaper, more labor intensive, and better fix is to get a tank sealant like

Or similar and paint the inside yourself.

 

but you might be able to put your finger "in" it ... yuk :>)
