clutch

[Shawnb]

25 plus year old clutch there is an enormous amount of chatter coming from clutch and clutch has stop working hard to push in nuetral and all gears. Is it possible to change springs are do i need to change friction plats or both. costantnant pro's have described springs as culprit with good clutch plate surface cleaning?????????? Also starter doesn;t turnover fast enough because of clutch tension, any help would be gratefully appreciated.

Have you tried all adjustment procedures? It may just be an adjustment issue.

Yep, I would start with adusting the cable at both ends as described in the tech tips.

The clutch springs are not the cause of the clutch chattering or not disengaging. The springs keep the clutch friction disc and steel plates pushed tight together, when they begin to fail you get more slippage than you want.

If the bike has sat for a long time, the friction plates and steels could be sticking together, so a good cleaning of them and a little bit of sanding with 220 or 600 grit paper can help as well.

If it's not torn apart yet, you could try some MMO in the engine oil to de-gunk the plates. Just don't ride it too hard that way because the oil will thin out some. Ride the bike, let it sit overnite, and check again for improvement. If it's OK, change the oil and ride. If no, tear into it. HTH

To me, what you describe is the tabs of the friction plates cutting notches into the clutch basket. Here's a pic from the manual...






So, set the bike on the sidestand and you don't even have to drain your oil. Check your clutch out, get some heavy duty springs and throw the old ones away.. usually less than $20, and measure your discs and check out the basket. Just don't cut the little wire to get the last steel disc off.. it stays. Slap it back together and ride off into the sunset.

I just realized that nobody seems to have caught that it doesn't matter what the clutch is like. If the bike is in neutral it should turn over fine. If it doesn't turn over fine there is something wrong with the starter or something else. The bike should be easy to push around (well as easy as a 600+ lb bike gets) if it's in neutral, and the starter should turn the engine over fine assuming a good battery and good engine.

2 problems?

Hi Cy,
interpreting Shawn's somewhat incoherent posts as best I can; I think that his transmission clutch rattles like a bastard and is hard to use and that his starter clutch slips so the engine don't spin fast enough to start.

I don't guess YOU realize that by having those notches grooved into the clutch basket, your clutches can't release properly and are kept from sliding back and forth along that groove, and it will make it hard to push in neutral, and in any gear with the clutch pulled in, and will also still grab and pull on the starter motor when trying to start. There could be MANY reasons the clutch isn't releasing properly, but they would all have the effect he describes.

For comparison... just pull your clutch in halfway and try to start it or push it around while in gear.

Ummm..... Tod, the clutch doesn't even come into play when the trans is in nuetral. It's just a flywheel basically at that point.

IIRC

Hmm.. I stand corrected on that. Another case of operating a keyboard before coffee cup and brain are engaged. Sorry Cy.

It could be that. What I do gather is that he appears to have trouble getting the engine to turn over in neutral, that points to a problem other than the clutch, also the OP hasn't stated yet if he has done the clutch adjustment procedure yet, but if you can't get it to start in neutral because it won't turn over that is the first problem that needs to be fixed, and I agree, it could be the starter clutch.

You will see several past postings on the subject of the "starter clutch". Thick oil, cold weather, synthetic oil. What you can do is heat the crackcase to bring the oil to reasonable temperatures and then try to see if the starter clutch grabs hold...if that is the root of the problem. If you get it started and bring the engine oil to normal temperature, you might just see that it is indeed temperature related. I have three xs11 bikes that have all experienced this phenomina at one time or another. It is in the single digits outside and I may go down to the garage just to fire them up and make some noise in the neighborhood. I'll bet at least one of them gives me trouble.

there is also a small knock while trying to start sounds like it comes from generator area which causes an drop in power but engine turns over faster with cluch lever pulled in. hopefullyits just sticking plates, and needs to be cleaned also was running automoive oil in engine and tranny for about 135 miles. I gather that as the real culprit but the chattering and clacking while riding hopefully is from sticking plates.
