Fella brought in a top end off an Ape into the workshop, what's the pipe in the head for, it goes down to a small hole in that circular recess?   |

Some of the big ones were diesel so I'd guess at some form of decompressor system.

Good call boss, he said it was badged as a '400', the piston is roughly 51mm, three ringed and fucked, the barrel weighs a ton and is very long, the stroke must be huge. Do you still add 2-t oil on a diesel? Maybe it was what killed this piston?    |

Just done a bit of googling on decompression heads, appears the vespa caio had this feature due it's small CC's and high compression which is probably what this ape barrel had... Ta!
