75 GL 1000 Engine seems disconnected from drive train!

Postby ralperin » Fri Sep 12, 2014 10:48 am



I've had this bike since 1986. Never a problem. My first long ride ever (300+/- miles) to Quebec and with no warning the engine seems to have become disconnected from the drive train. Noise coming from inside sounds like ice cubes in a blender. Any thoughts? Clutch? Tranny? I'm told I have a wet clutch! Is that true? I'm told there is a chain in there, true? I know in May when I woke up the bike from the winter nap the oil was right up there. Never ever lost oil in a summer.Not able to see any oil in the sight glass, however no signs of a leak or burning oil! Don't consider myself a mechanic but when they get it apart I want to sound Iike I know something, so I'm not raked! By the way the engine seems to run fine with no warning lights at all! Can someone suggest a possibility or two or three, as to what may have happened in there?

Centerstand the bike,put it in first gear and pull back the rubber boot that covers the driveshaft.Turn the rear wheel.if the shaft turns,the problem is in the block,if the shaft does not turn pull the wheel and swing arm off and look at the driveshaft coupler.

The ice cube's in a blender noise is definitely coming from the engine area! Approximately near the gear shift!

Ok.if your positive the sound isn't traveling to that area from a broken driveshaft then its time to replace the engine.Probably cheaper that splitting the case and replacing the ice cubes.
Yes there is a primary chain.Unlikley it broke.it literally can be anything come apart.You can look inside but finding parts to fix it might be a problem.
I bought a "junk" bike,no title just to get the motor.Used a bunch of my parts to make one running engine.

Yes, you do but, it's not something to get excited about. Some motorcycles have dry clutches, some have wet. GL clutches are 'wet'. That means they are bathed in oil and, because of this, it's important that the proper type and weight of oil is used so it will operate properly.

SNIP..."I woke up the bike from the winter nap the oil was right up there. Never ever lost oil in a summer. Not able to see any oil in the sight glass, however no signs of a leak or burning oil!"
This sentence is confusing. "the oil was right up there" and "Not able to see any oil in the sight glass" don't relate. When a GL sits for awhile, oil migrates back into the clutch housing causing the oil level to look a bit lower in the sight glass. But, you should still see oil in the glass between the two lines. So, check your oil. Virgil has given you excellent advice. Follow that and re-post.

I know it's a long shot, and the location you're talking about hearing the sound is miles away from where I'm thinking your trouble may be, but have you inspected and greased the final drive splines in recent memory?

Loss of the splines on the final drive will certainly act as if the engine is disconnected from the drive train... and although I've never heard the sound it makes when the splines are stripped off, I bet it makes one heck of a racket...

It is worth a look, before you replace an engine.
I am wrong as often as I am right concerning what is wrong with someone else' motorcycle without having seen the machine in person. Guessing with limited information, as to the source of the trouble, is sketchy at best.

I snapped a u-joint right in half in my 75 years ago.I'd say it's the weakest link and I'd be looking at that first.Noise like that can travel all over the place.


If I'da known it would last this long,I'da taken better care of it.
