GL1100 engine rattles under load?

hello, I bought my 81 goldwing interstate a few days ago with 67k miles for 775 bucks!! it smoked like a steam engine on the way home, I have since drained the extra 2.5 qts of oil it had in it (about 6.5 qts total!! :() and the smoking has went away after it the puff I get at startup from the valve seals.



I have a question, if I put the engine under a heavy load at low rpm (trying to pull a gear to high) the engine rattles from the bottom end, like the crank bearings have to much clearance, but the oil light doesn't come on, and above 1500 rpm or so its fine, I save above 1500 because the carbs need ballanced right now, and it will fall down so low in rpm that its is only doing maybe 600 rpm and hitting on one or 2 cylinders..



does anyone elses bike make this lower end rattleor should I look into rebuilding the engine in a month or so? (riding season is allmost over in ohio :X)

Carb sync probably the entire problem... search for primary chain rattle..

guess I should look around befor posting a question :doh:



looks like I should go buy some seafoam and run it though the bike, since I am having carb problems with it.....

That low rpm high load rattle is common.
The 1100's like to run above 2500 rpm.

I'm wondering where all the extra oil came from.
Did it smell gassy or look like chocolate?

no, guy wasnt a bike guy.....he just tried to change his own oil and over filled it, it started smoking right after that, and he didnt put 2 and 2 together to figure out it was just over filled

Nash great buy.

The knoking is not realy a mechanical issue in the engine. It is gemeraly caused by cylinders out of sync and one piston is driving another sortof. This can be ignition sybc or carb sync. I have had my gl1000 for 3 months In that time it has rattled lots and little After I set the points and timming it was quite a bit quiter. It had issues some times and would get realy bad. I finaly pulled the carbs cleaned them and repaierd a broken plenum o ring it is smooth take off now no knocking. The other thing is these are wet clutchs and you have to slip them as you give it gas. If you dump them like you would a dry clutch they will knock>

1100 s aren't full of low end torque, below 2500 nominal rpm they like acceleration to be gentle, but over 3000 you can beat the hell out of it and if the engine is balanced 8000 rpm in quite a thrill. I find I have to be in 3 or 4 since I hate traveling over 190 Km/hr. The engine can be spun at 8000 revs parked, but it may take you some trial and error and trust to try it, from experience and testing out the motor I fully trust the 1100 at any speed to 8000. But be aware balancing the engine is beneficial in the lower ranges and I dscovered from the balancing my RPM went down at a given speed. At 4000 RPM, I am speeding along at 105 KM/hr based on the speedometer of the bike, rpm seemed to have drop 200 RPM for a given speed. Does not make sense but this bike at 30 years old does everything well.
