Title: Clutch
Post by: 2ndsojourn on August 25, 2014, 04:21:53 AM
Hello Dan,

Have a strange problem with the drive clutch.  Removed the engine covers for cleaning.  When I installed the clutch I had to remove all of the slack to make the clutch work.  Now, no mater what I do the clutch will not disengage properly.  When I downshift into the first at a stoplight and leave it in first gear, the engine rpms will decrease and once in neutral the rpms will return to normal.  Maybe this is normal, but I do not remember the bike behaved that way.
Tjanks.

Sounds like the clutch is dragging. I would do the clutch pushrod adjustment. Did you  have the left engine cover off that has the clutch lifter mechanism in it? You may need to take it off again and check if everything is in place. 13102 in the attached picture is the part that wears out the most, where the cable attaches to it, the swivel pivot wears and the clutch doesn't disengage fully.

The clutch adjustment is not described in the service manual.  The has a slightly different clutch.

What clutch do you have? What oil are you using?

I am sure the clutch is factory as this bike was of the highway patrol.  The oil in now is yamalube 10w40

That oil is fine. Either it's an adjustment issue, it has a Barnett clutch in it or the steel plates are warped. Or as I mentioned earlier, the clutch lifter mechanism is worn out.

Here's a link for the adjustment procedure:
