Greetings all...
Bit of a barn find type situation but I now have a JPX 425 engine in my possession. It is missing an exhaust and an owners manual of what to change and when.
It came off a home made trike that replaced it with a more powerful engine a few years back. They guy recently passed away and his missus had a clear out.
Would anybody perhaps have a PDF copy of the engine manual? My background is in hang gliders and so pretty clueless about engines.
Also, will likely need to get some local bike shop I guess to put together an exhaust for me... any chance somebody has any specs or technical drawings of the engine? I found the second picture off another post on here and it is the best I have seen re: exhausts.
I know a lot of these were direct drive - what size and range of props should I be looking for? I think it goes to 4600rpm...
My thanks....
