How mutch lash is OK?

[Guest]

On my 82 1100G shaftie,

I've checked the "rear end" gears and the ones that are just inside the "motor/tranny", (where the drive shaft goes in), for visual lash and they seem to have minimal lash, (also replaced the drive hub in the wheel). With the bike not running and in gear, there is about 5/8" or so of lash at the rear wheel in 1st gear. To clarify, I made a mark on the "rear end housing" and the wheel hub with a sharpie with the wheel "lashed" all the way forward. I then rotated the wheel rearward untill it stoped and measured the distance between the 2 lines.

The reason I'm asking is because IMO the transmition or something is making one hell of a racket untill I put a load on the system. In other words, sitting at a sotop light the motor sounds like it has marbles in it. But when I just start to apply the clutch when taking off the noise goes away completely.

Not quite sure what to look for or where to start with this one.

When I "rock" the rear wheel back and forth in gear,(not running), the noise seems to be most prevalent in the area right under the starter.

Any experienced advice is welcome...........................

And thank you in advance

Sounds like you should take the clutch cover off for an inspection.. It may be as simple as the Big nut on the clutch basket being loose,

Changed the oil last night and while it was empty I took the clutch case off to give a look-see. Everything seemed to be in order with the clutch. I measured the steels and disks as outlined in the manual and they are about 3/4 or so through their life. I didn't actually put a wrench on the " big nut", but I'm guessing that as long as the lock washer is still bent tight to the nut and I don't see any movement, it hasn't loosened up.

I have asked random people how they think the " transmition" sounds to them and most have said " these things were a little noisy like that anyway, werent they.....?"

That's the part of it I don't know about. I might go to my local dealer and see what their opinion of the noise is. They actually have a couple of guys that use old 8-valve Zuk motors in their flat track bikes.

Sounds to me like it would either be loose springs on the back of the clutch basket or the beginnings of starter clutch failure

Flatline,

Your suggestion sounds appropriate to me. Just walking around the bike with my head stuck in the motor, the noise does seem to be louder on the starter side. Almost like it's coming from right under the starter area. I think I have the gasket for that side also. Maybee I'll crack that side open to see what I can see..........

Just because I don't know,.... why would the starter clutch/gear noise go away when I loaded the transmition though??

x2 I had a similar noise on my GK. Its gone now that I've rebuilt the starter clutch assembly. In my case, I'm convinced that the noise was due to the loose starter clutch bolts. Another possibility is the forward end of the driveshaft has snapped. I've seen that happen twice. Good luck and let us know what you find.

Was able to get that flat track racer at the dealer to listen to my motor Saturday. The dealership was having an open house so all of the employees were outside doing their thing. In his opinion there's nothing out of the ordinary that he could hear. With that, I'm not going to concern myself with it.

At another bike place I got to meet a fellow GS'er from my area, Davidduarte


Thanks all for your generous input.

Here is a video of the sound I am talking about. When you see the vid, it's obvious it's at night. The audio is more of what I am interested in. Any thoughts or comments would be welcome.

Listen to the difference between when it's sitting there "freewheeling" at idle and when I "load" the tranny.

Thanks
