Re: what did you do to your motor bike today?
Wow, a lot of dis-assembly there, I never pull the studs or piston to change the jug gasket.
Also, what do you have smeared on the head, there?
I put head gaskets on dry. I guess I'm used to working on Subarus wehre the gaskets go on dry, but it works completely fine on these little engines as well.
As to what I did to my bike today, I guess my nicely tuned RT carb and home made expansion chamber pipe added too much low torque. Because I sheered the woodruff key on the output sprocket today! That was kind of a PITA, mostly because I had to hitch hike a way home. But it wasn't too bad to fix.
