fresh engine build - lubrication - best practice?

[ssdd_andersson]

Marty used to be a rep with Penrite,he recommends an oil thats a bit hard to find,its called Endro.
The specs on on the Pentrite site,its a 25w70 with all the zinc ect but is designed expecaly for air cooled older bikes over 1000cc that get worked hard in a hot climate.Someone might think a Laverda rider had an input in its formular.

Yeah
Heat is no friend of a aircooled engine  

But where I live the summer weather is more like "Water is not Frozen"  , Heat isnt a real problem ,
Still A good Synthetic Motocycle Oil stands more heat then any mineraloil
