Hey can't find any answers versy helped me last weekend with a question but now I got the shaft; bolt with spring tension to lever cable well anyway no matter how I but it in and tighten down L16 bolt in valve cover it allows shaft to slide in and out about 1/4 inch it does stop it from coming out more than that but is this normal? Or should the shaft be tight and only rotate to hit rocker arm  for decompression? Any info much appreciated I've had it in and out several times very aggravating lol thanks all.

I don't think it's wrong bolt because L16 refers to length and it's short one with gasket on it ? Any other thoughts as to why it won't seat fully ?

I've checked everything and the shaft flats sit over the rocker arm and it hits when fully seated and when it's backed out a bit. I've adjusted to 3 mm on the decomp solenoid. I'm thinking either hardware is out of spec or maybe heat up the oil seal to see if the shaft of bolt will go in further. I don't see any harm leaving it like is. I noticed that the shaft has a boss flange should that sit in oil seal or just up against my only worry is maybe some oil leaking out of the seal. I might try new hardware. Anyway thanks for your replies!!!

Yea I've looked in manual and the c markings on head of bolt match it has gasket on it either shaft or bolt is worn is my only guess I'm in heath Ohio. My only worry is a oil leak from the shaft not sealing to the oil seal tight enough.ive tried a different M6 bolt but same slop in it just a hair or lateral movement.

The spring is in the catch under lip on the head cover and hook is on plate / bolt contraption but it does seem to skew when I push it in maybe not allowing bolt to be flush up against the seal I tried pulling spring back when pushing it in tbut does angle itself when tightened

Yes, see attached photo of mine.  This is before I got the spring captured correctly under the catch lip on the head cover.  I had to correct this recently myself - the whole contraption is a pain to get situated right.  Also Note: my cable is a little  limp even when the adjustment is correct (stretched from use).

Does your decomp work and open the exhaust valve?

I don't think a leak at the seal is a big concern as long as the seal is in place.  With the rod running through it, oil doesn't really doesn't have a place to escape (and there's not a ton of oil getting up in that area either).

I'd be more concerned with the actual function of the decomp itself if the actuator rod is sticking out.  Does the lever align with the cable so that the cable is directly "above" at 90 degrees - or does the cable have to make a sideways angle?  It should be aligned squarely.

I’m saying the cable should not have to reach outwards where it connects to the lever (it should be directly above it going straight down).  The bracket is angled (it’s really the only way the bracket can attach that makes sense).

Remove the exhaust valve inspection cover.  With the motor at TDC, this is how the “half moon” flat should be situated above the rocker arm when the decomp solenoid is set at 4mm on its shaft.  It has about 2-3mm of clearance above the rocker arm.

If your actuator rod isn’t going in all the way, that half moon flat won’t be sitting above the rocker arm where it needs to be.  If the half moon is situated like this, and you still have extra space on the actuator rod where the spring goes, then somehow the bike got a wrong actuator rod installed (too long, perhaps from another model bike).
