Clutch Adjustment

Post by bstig60 » Fri Aug 24, 2018 2:49 pm



I have a problem with my clutch dragging a bit when the bike is cold. It is OK after the engine warms up. The only adjustment I can find is the one on the clutch lever. Am I missing something?

There are no adjustments that I'm aware of. When was the last time you bled the system? If you have air in there, it won't work to it's full travel. Needs to be completely bled every-other-year.

Hydraulic actuated clutch = no adjustment.
Clean fluid is important, if there is air trapped it may actually become worse after the bike heats up and the air expands it may create pressure in the system. It is possible that the pressure release passage is clogged an not allowing the clutch to fully release.
If you pull the cover off the clutch master cylinder and SLOWLY pull the clutch lever back you should see fluid come out of the pressure relief orifice, also a good idea when doing this to cover all plastic in the vicinity so brake fluid does not accidentally get on any plastic parts.

Also it has been my experience that a lot of clutches "stick" slightly when cold and if the bike is started in gear with the clutch lever pulled the bike often tries to pull forward when started, until the clutch pack lets loose.

Try getting in the habit of starting the bike in neutral when cold and let the oil warm up a bit before putting it in gear.

I have never bled the clutch. I have had the bike a year and this issue has been showing up in the last few weeks. I noticed it when I was getting ready for a trip to the Keys about a month ago after the bike had set for about a month... I adjusted the lever adjustment and it was fine for the trip. The clutch has always began to be engaged before I thought it should, vs. my 1500, but I just assumed it was the characteristic of the 1800.

Now that you mention it, I have not bled the clutch on my Wing either, when I first got it, I used a turkey baster to remove most of the old fluid in the master cylinder, making sure I did not uncover the port at the bottom and let any air into the system, then refilled with fresh fluid. When it went in for the brake recall I had them flush and bleed the clutch while they were working on it, I am probably due for a bleed and flush, will do that sometime after I return from Wingding in a few weeks.
I am not sure this will work on the Goldwing, but on my Yamaha Venture when I would need to flush and bleed the clutch line I would always end up with air in the line because of the design of that system. When I was done and had bled as much air out as I could, I would set the bars so the clutch master cylinder was as close to level as possible. Remove the cover from the master cylinder and SLOWLY squeeze the handle several times watching for any air bubbles. I would take the handle of a screw driver and tap on the lines from the bars to the slave cylinder to agitate the air and help it rise up. Repeat the lever squeeze and then tie back the lever over night with the cover off to allow any stubborn bubbles to rise up. The next morning repeat the squeeze the lever trick, if no bubbles I closed it all up and journeyed down the road.

If when you squeeze the lever you do not see fluid returning, I am told you can use the wire from inside a bread tie to clear that orifice out, just be sure there is no loose bits on the wire , do not want that in the fluid.

Need to flush the clutch hydraulic fluid as well as the brake fluid at least every two years. Lots of threads on this site regarding this.

If not done on a regular basis a lot of crud will be deposited in the clutch slave unit that is on the front of the engine and takes a bit to get to - found this out when I owned my '08 1800. Having clutch engagement and operating issues could be because of this. Easier to flush the clutch system on a regular basis than to remove, clean, replace clutch slave parts, and it's less expensive and time consuming.

Been there, done that! I have a 200 mile trip coming up tomorrow, so I am going to leave things alone until I get back, then I will bleed the clutch system, its cruddy to be sure.

My clutch was not disengaging fully after installing handlebar risers, then it worked ok. I took it out and had a great ride. Then I went on a fairly long ride and it quit working about 60 miles from home. You can imagine how much fun I had getting home with no clutch. Today I finished flushing out the system and it seems to have fixed it. I will have to get all the coverings on and test it out in a day or so. One thing I did find was that although the fluid seemed fairly clean, under the white piece of plastic at the bottom of the reservoir was a lot of junk that needed to be cleaned out. After that experience I would hesitate to take it on a long ride if it is acting up, since it could get worse far away from home.

Yes, I have had to make it home with no clutch on one of my Virago's a few years back when the clutch cable broke. My ride went fine yesterday without any problems other than getting soaked at a stop light only about 3 miles from home. I plan on flushing the clutch system out next week before I go on another ride. I will report back what I find.

To bleed/flush the clutch on an 1800 is not the easiest maintenance issue, lots to be removed to get to the clutch slave and bleed screw. If this has not been done regularly, there will be a lot of crud in the clutch slave, and it should be taken off and cleaned. Might as well do this when you are in there to bleed/flush the fluid.

An '03 or even an '08 1800 being some 10 or better years old will have crud in the clutch slave. Here is a picture of the inside of a clutch slave that has not had the fluid flushed on a regular basis:

The only issue I had on my 1500 was the alternator stranding me at somewhere around 50-60k. Feels like the 1800 has a few more issues.

Don't think there are more issues with the 1800 than 1500. I had two 1500's and never had any particular problems with either of them other than regular maintenance... Timing belts were changed when I bought both of them because I didn't know when or if they were ever changed. Changing rear tires on the 1500 was a pain to say the least.. Had a cracked vacuum line on the 88 causing surging that took some time to find. 99 never gave me a problem from day one and was a great ride. My 1800 has been great except for a coolant leak which required pulling the fuel tank to get at a loose clamp. Was a PIA but I learned a lot about the bike in the process.

Is there a video or a procedure somewhere other than the service manual for bleeding the clutch master/slave?

Bleeding/flushing the clutch fluid is quite intuitive. You have to remove the lower front cowling, and work your way back to the clutch slave. The OEM service manual is quite good with regards to pictures.

Honda has an extender line on the 1500 that goes from the clutch slave out to the side of the engine, good design - should have done this on the 1200 and 1800. My son-in-laws Moto Guzzi California Touring bike has a hose that is from the clutch slave to under the seat - makes bleeding/flushing the clutch system fluid easy.

Behind the lower cowling there is a canister that you need to remove. Also the bracket that supports it will have to be unbolted and moved out of the way. The bleeder valve is behind the bracket. It was really easier than I thought it was going to be. Good luck.

For getting air out of the line or self bleeding.

I read on another forum where the writer said you can pump pump the clutch lever a couple times and then pull it within 3/4 of an inch from the handle, tie it off and let it sit over night. I guess I need to try this and use a piece of wood 3/4" to pull the lever to it tight and then tie it off.

I tried that and it didn't work for me. I must have had a blockage that didn't allow the fluid to drain.

If you haven't already, do yourself a favor and get a set of Speedbleeders. They make the process even better and faster, and can do it all by yourself....get enough to do the brake system too. Makes it super easy the "next" time too.
