97 Sportster remove head

[Mcardente]

Hey there, do I need to replace the Orings/gasket if I remove the head cover off my 2-stroke engine? Yesterday I dropped a bolt down the cylinder while spark plugs were out... soo smart... I know... (bolt is 100% non-magnetic)

I just replaced the Orings 3 yrs ago...

Also, I can’t remember what I need to torque the head bolts to when putting back together, any help out there?

I'd say if they they look good, I'd lube them up and use them.

ok thanks, only 17 foot lbs??? That seems wayyy low? Am I reading that correctly? I thought it’d be more like 70-90 ft lbs...
