I'm hoping to change the head gasket on a recently purchased Nippa this weekend - it shares the 846cc ED20 engine with the Cuore (L201 and L501 I think). Can anyone tell me the torques values and tightening sequence please? I'd buy the maunal off the site but a)I'm too tight! b)I can't find a link to actually buy the manual (maybe I'm tight and stupid?!) c)I need it asap!
