Clutch Thread

A while ago I did a clutch soak. Helped a bit.

This year, on two rides ... 1000 miles a month ago, and I got back yesterday from a Ride Around Texas ... 66 hours, 55 mins, for the record

I am having clutch issues with the venerable '05. So much so that I can't select neutral from 1st with the engine running. The clutch is dragging that much. I can't roll it back easily in 1st either, and if I give it revs it wants to move.

Clutch is on maximum travel setting, and fluid is new. Problem doesn't get worse if I sit holding the clutch in, suggesting that the slave cylinder is not leaking fluid back.

What to do?

I could strip and soak it again. I could try Rotella T6 instead of Rotella T. I could strip and clean ... again

... or I could pay $350 to upgrade to the 2016 clutch and have an end to the issues.

What do you think?

Give it a good clutch fluid change and bleed and a clutch plate clean and oil up.
No use soaking, a waste of time.

I agree about the soaking. Just a healthy amount of oil on clean plates when you re-assemble.

What you describe is a classic case of air in the hydraulic fluid. And/or moisture. My GL1800 had to be flushed every 2 years else by 3 it was unrideable. Garage kept.

Agree,
Just make sure the metal plates are real clean and friction material isn't contaminated. And yes, a liberal amount of oil, yum !

I'd like to avoid the large bill. Even with the clutch in its current state I just rode 3100 miles in 67 hours, so my problems are manageable.

Still, I want it fixin', so I'll try the fluid change first, before I start pulling off Canyon Cages, and other crap to get to the clutch cover.

Impressive. RAT is what? About 3300 miles long and little or no highways.

I started in Paris, TX and ended there. Route was 3094 gps miles, with very little Interstate.

For fun, it included the Galveston Bay Islands, the ferry, South Padre Island, Big Bend National Park and the River Road from Lajitas to Presidio.

It was a wonderful experience ... even in March with rain, fog, some freezing temps and some 90F

I'd fully recommend it to anyone who wants to test their bike and their abilities, and enjoy some wonderful scenery.

ps ... the "flower-sniffing" version allows 85 hours, rather than the 70 hours for the Gold. That would be pretty damned awesome too if you prefer a more relaxed pace (or more sleep).

What to do?
Steve,

Yamaha's new clutch basket has extra holes in it now, maybe to oil the clutch plates better? I might drill some smaller holes in mine, or just replace the clutch basket with the improved part..

Clutch soak. Thoughts and questions.

Your clutch plates may be dirty or warped now, or the hydraulics may have a problem. A cylinder that is scored near the end could cause this symptom.The center rod and ball may be worn, also. No certain answers, there, just check things off the list and move on, until you get it fixed. Happy hunting.

Yes, but no matter how much internet lore is fond of "clutch soak" the only reason your clutch will not fully disengage is that the slave cylinder is not pushing far enough or hard enough to separate the clutch. Engine forces through the clutch are so great the plates will not stick to each other if slave cylinder overcomes springs.

When clutch basket is worn the feel at clutch lever is usually awful. Most all clutch basket wear is found on off-road 2-strokes which are forced to feather the clutch in slides and hills to make up for shortcomings of the engine. Fewer off-road 4-strokes ever see clutch basket problems. And unless you modulate the clutch to control wheel spin I don't think you'll ever need a clutch basket on the street.

Don't know where you would get a big syringe but if you can get a helper to deal with one end while you deal with the other, swap the entire old fluid out in one pass not giving air bubbles a chance to rise. I bought one of these several years ago and its one of the best things Harbor Freight sells. Also need to buy a quick connect air nipple because I don't believe this kit comes with one, or it uses the oddball only seen in Asia. And of course one needs an air compressor to power this thing. http://www.harborfreight.com/brake-f...der-92924.html

Heck, if you only have a vinyl hose don't let my words above prevent you from flushing it the old fashioned way. That usually works but sometimes not. Worked on my GL1800.
