Bad Gas

Post by Barracuda3077 » Tue May 22, 2018 10:06 pm



I'm just wrapping up a 1,650 mile trip on my 82 1100. This am, I did a bad thing. I filled up at a non brand gas station and the problems started about 50 miles down the road when i came to a stop for construction. Anything below 1,500 rpm, the idle is really rough. When i get back above 1,500 rpm the bike smooths out like normal. Today was 350 miles with 44mpg. I filled the tank with name brand gas when the tank was 1/4 full. I only have 121 miles to go before home. Besides draining the tank, puting a new fuel filter in, sucking Seafoam into the carbs and letting it sit clean out the slow jets, is there anything else I should check. Before this tank of gas, the bike was purring like a kitten and was blowing the doors off the other tractor sounding bikes I was riding with!

I had that happen before, as soon as I burned through the tank and refilled it with quality gas, the problem was fixed.

Okay, I'll fill up before blasting out of town in the morning. I always put premium in. Others also are also having problems. Thanks for the quick response!

Just wasting money on premium, Goldwing is a low compression engine designed to run on regular. Better to spend the extra on Non-Ethanol Regular if you can find it.
They say 98% of all Hardleys ever made are still on the road..... The other 2% made it home. :lol:

+1 on the premium gas buy. These engines are not designed to run on premium fuel. You are wasting money as these engines are more likely harmed than benefited by higher octane fuels. Unless an engine pings on regular fuel I say to use it whenever possible.

+4 on NOT using premium gas, you are actually hurting the engine.

it is harder for it to combust, because it requires a higher spark voltage, and higher compression ratios than what our bikes have.

premium tends to build up carbon deposits on the valves and cylinder heads.

OK......... Where are you +1 and +4 guys getting your information that premium (high octane) fuel causes harm and carbon build up ??? You need to find a new (correct) source of information.

As far as increased cost, here in So Cal the difference between regular and premium is 25 to 30 cents based on the riding around I did today. The OP claimed he was getting 44mpg. So .30 per gal / 44mpg = ~.007 cents per mile increase in cost. I agree that the engine is designed to run on regular fuel. Per the Honda Owners Manual (for 1983) it states to use any automotive gasoline with a pump octane number of 86 or higher, or a research octane number of 91 or higher, may be used. But as far as increased cost I would cut him some slack and let him splurge on his motorcycle. But please don't tell him or anyone else that using a higher grade of fuel will harm an engine.

Personally, I'd suggest continuing to use regular gas & continue to add Seafoam for another tank or two. Seafoam works amazingly well, but it doesn't work instantly. In the case of really bad fuel (been there, done that), it can take 2-3 tanks of treated fuel to clean out all the crap. It worked for my bike under identical issues...

Follow up, 3 other people whom I was ruding with also reported bad gas.

Once I got home I doubled checked to make sure that sure nothing was amis. Low and behold i found a bolt that was supposed to connect the intake tube to the carb was sheered off. So I've removed all the intake tubes, and the bolts along with the O-rings are on their way. So bad gas along with a vac leak I'm guessing is what made me think my bike was having its own personal earthquake.

Thanks everyone!

bet it runs better when you get that bolt fixed, and the gasket sealed tight.
