GL1100 No smoke at start up then smokes when engine warms up

Postby washbtiz » Sun Aug 17, 2014 6:56 pm



This issue seems to be the opposite of most start up smoke issues. I get no smoke at start-up then left side wont stop smoking at all when engine reaches temperature. grayish white smoke. Head gasket was just replaced. issue started immediately at first start up. I put white paper towel over left exhaust and it was perfectly dry. Coolant stays full. Engine runs good and fast. Took out on freeway ran great. Got off smoke was pouring out the left side. Once smoke starts it doesn't stop. HELP

grayish-blue smoke would make me think you have an oil leak... however, I can't think of a reason (aside from blockage in the drains in the head) that would make the engine smoke after start up from oil.

Generally, smoke after reaching operating temperature would make me think it is a head gasket. Also, unless you've removed the crossover pipe from the exhaust, there is a certain amount of flow balancing that occurs while the engine is running from left to right, right to left, exhausts. Not enough, probably, to mask which side a significant oil smoke or head gasket smoke is coming from, but there is some balancing.

Have you pulled the plugs to see if their soaked in oil, or if they appear to have been steam cleaned on the left side? That's where I'd start looking for trouble. If it is oil, I'd pull the valve cover to see if the oil is pooling in the cam/valve cover area while the engine is running. You could let the engine run a bit, until it starts to smoke, then pull the valve cover on that side to see if there is an extreme amount of oil. That's my best guess.. that oil is pooling under the valve cover, then running down the valve stems into the cylinders while the engine is running. If what I think is true, your oil return passages/ports may have blockage causing the pooling of excessive amounts of oil while the engine is running.

That's my best guess from half way around the internet without having access to your bike.

Check it out. None of the checks I would suggest cost anything to look at. There are a LOT of really knowledgeable folks that will be able to offer more insight as soon as they get a look at your trouble.

Thanks...I will check those out. I did pull the left side plugs no oil and dry. Did not appear to be steam cleaned. Shouldn't valve seals stop even excessive oil pooling running into combustion chamber. Could seals be bad?

The seals really aren't designed to withstand pooling oil, if you know what I mean. If they're original parts, they could be allowing some oil to get past them, and under normal operating conditions the amount would be burned during normal combustion. If there is a lot of oil pooling in the valve cover, it can be more than the valve seals can wipe clean, causing your trouble.

I could be a mile off in my guess here.. just keep that in mind.

Is this the first time you have "ever" started this engine? I guess my question is, did it smoke before you replaced the head gasket? If not then there is no sense looking at the seals or anything else but the new gasket job.

Did you remember to carefully position the o-ring that goes around the little transfer pipe in the head? Regards, Johnyy

Problem started after head gasket replacement...repair failure! Those oil return passages are huge-no way they are clogged! There is not 1, but 2 o-ring seals around each oil orface between head and block, and they ARE vary important! Also, reserfacing of the head, and retorquing as needed after 1 heat cycle is critical!...that's not a guess. :roll:

I was extremely careful with both o-rings on the oil restrictors, in both heads. It's looking like it may be a head torque issue, as I checked the left head torque and 4 of the bolts had dropped to the 25-30 ft-lbs range. I know positively they were torqued correctly as I rechecked them 3-4 times when initially installed.

It begs the question - did you retighten the heads after one heat cycle? And let it cool down overnight before? Regards, Johnyy

Retighten- and hope for the best, But chances are you will have to redo the head gaskets again, It is a vital step that helps to "seat" the gaskets preventing oil and or coolant leaks. Some prefer to retighten for a third time after 100 miles, but I think that is redundant. Also check heads for resurfacing. Also it don't hurt to retighten the cam bolts either. While your in there - redo the valve seals. Regards, Johnyy

OK...God and my brothers fixed this for me. I did not re-torque the heads after the first full temperature startup. When I checked the torque the left head had slipped to 25-30 ft lbs. I was fortunate enough that after I re-torqued the heads...NO SMOKE FROM EITHER BANK. If I have any trouble down the road I will install new head gaskets from scratch but for now FANTASTIC. Thank GOD and all my brothers!!!

Also...not only no smoke but engine temperature dropped and idle was considerably smoother. THANKS again to God and all my brothers
