benilli dynamo information 50 or 65

#1
Hello all,

I have purchased a benelli dynamo mini trail , I was looking for infomation on oil mix engine identification 50 or 65 cc, trans oil what year etc,. I already borrowed the wiring diagram which is identical to mine. the engine was stuck but looks to be able to be cleaned up. it didnt have a head gasket or barrel gasket which seems odd to me. any parts manual or info would be appreciated. thanks in advance.

Sachs 50cc engines of the same period used 25:1. Not the same engine but probably very similar.

Transmission fluid in that Sachs was traditional ATF. Dexron/Mercon II, III, or IV is a good equivalent. Also on Saxonette, there was a cylinder gasket but no head gasket. I know the engines are different but it wouldn't surprise me if the same things apply.
