|Tappet adjuster smacked the access cover a few times.|
A nearby car revved it's engine at me, so I of course was obliged to return the gesture. A quick twist of the throttle, *BRAAAAAAAAAAP* the bike revs smoothly to 8000 rpm followed by a disheartening *CLACK CLACK CLACK CLACK*!
I managed to limp it home. It doesn't sound like there's anything bouncing around in there, but it doesn't sound good either.
It appears that my motor decided to throw a valve tappet adjuster and nut.
Here are pictures of the resulting carnage: (click for big)
|Tappet access cover damage.|
Good tappet adjuster in rocker arm on the left,
bent tappet adjuster and missing nut on the right
|Bottom is the bad tappet adjuster: damaged threads and bent shape.|
I believe my riding season may very well be over.
I'll be pulling the motor soon. This is where things get interesting.
Note: the tappet adjuster screw that went was an INTAKE, not one of the exhaust tappets that I adjusted recently.
