Bad exhaust header gasket?
« on: April 06, 2026, 09:27:36 PM »
Black soot on my upper left cylinder right behind the exhaust header. Tightened the upper header bolt about a 1/2 turn and the lower a 1/4 turn. Will clean up and see what it looks like after some miles. Possibly exhaust gasket going south?

Looks like it, I would say. How old are they?

Oh, only 35 years old or so. Damn, a Guzzi is so expensive to keep up.  :grin:

Hello Glider----pull the exhaust bolt down thingy (you can tell the thingy--its round)apply a generous amount of Fubar grease around effected area,toque to specks,or as they do in Pakistan tighten the hell out of it.Probably wont help your problem,at least youll get to spend a day workin on your Guzzi.---See you down the road Bro!

There should be a way to renew those gaskets instead of forking out money for a new one every 35 years.
