82 GL1100 Clutch Slips When Cold

Postby Dr.Ew » Wed Jun 27, 2012 3:12 pm



On my '82 GL1100 (built as a standard, but with Hondaline fairing and luggage added), I am having a problem that only seems to occur when the engine is cold. When I first start out in the cool mornings, 1st gear engages just fine, but as I accelerate, I can feel it slip, allowing the engine to rev while not giving full power to the wheels. If I accelerate gently, it will stay engaged, but any hard acceleration causes it to slip again. Higher gears perform the same.
The problem only occurs for the first 1-2 miles, once the bike has warmed up, everything shifts and engages normally, except an occaisional slip when at freeway speeds, again, only for hard acceleration.

Obviously my clutch needs work, but what I'd like to know is if it would even worth trying to adjust the clutch cable or if this is a bigger issue involving replacing clutch plates or the like. If it is just the cable, I feel ok tackling it, but if it involves clutch disassembly, I'm not so confident! Has anyone else dealt with this kind of issue?
Thanks!

I'd be inclined to loosen the cable at the engine first and then the handle.You should see a bit of free play on the lever sticking out of the block.
If this fails to produce any results,you can run Sea Foam through it,just in case SOMEBODY used a friction modifier additive in the oil..Like Slick 50.....

It's not a horrible job to replace the clutch plates.Just leave the whole weekend open.It is just time consuming.
Come to think of it,I'm not so sure you need to remove the engine.Maybe just the wheel and swing arm.?????

Rear wheel only - you can do it without removing the swingarm.

Just a thought, what oil are you using?

Castrol 20-50 in one and Delco diesel oil in the 1500.
Both are good.I change every 3k miles.

Oil wise, I followed the data plate on the bike. I'm using Valvoline Motorcycle 10W40, label states "superior wet clutch protection". Just changed the oil & filter last week. I've had the clutch issue since I bought it, but wanted to settle some of the other issues before tackling it (like the previous owner using CAT5 cable to run power to the tail-lights... :roll: ) Should I switch to a heavier oil here in the heat of summer?

Look at the spec sheet or owners manual to go "by the book" for the temp range and viscosity.
Generally you use heavier oil in the hot season.
It's always hot down here ,so I just stick with 20-50.
The last time I was in the Dakotas it was well over 100* and I had 10-30 in the gl1000.It got a bit noisy.

I don't believe your oil is not the issue, but it can be sometimes, just not this time. Had to check.

Loosened up the cable down on the engine end, and what a difference it makes! Before, there was very little free play on the handle, now there is about 1cm. I haven't been able to test it out in the early morning with a cold engine yet (will do that tomorrow morning), but after loosening it up, there was none of the slippage. Even when I took it out on the freeway, there was still no slipping. Hopefully this will hold true for a cold engine! Thanks!
