Thanks snanceki,

I had it towed to the independant mechanic and I'll find out tomorrow. One thing I learned is I can now change the plugs in 90 minutes.

Do any of you know how important the rear airfilter support stand is? I noticed that the support post at the rear of the left and right engine have "fallen" off. It looks like the air filter housings would clip into these posts and mine are gone, so they are "resting" on underlying parts.

It looks like the replacement "posts" would need to be epoxy glued to the header, but not sure.
