Hey folks,
Just a small town farm boy here from rural Saskatchewan, Canada.

A few weeks ago I picked up an '81 CM400T bike from a local kid who was moving out of the province. It seems to be in pretty good shape, but the engine was partly disassembled to replace the gaskets so I've got some learning to do. I've found some nice pics of a bike online that I'm going to try to mimick for this project.

Hoping to get some good tips and meet a few experienced hobbyists to share the journey with!

Cheers,
Hoffer

Thanks for all the messages! Here are some pics of what I picked up.

I'm hoping to modernize it, very much like the bike on this page:

I bought the bike with the engine already removed, and found that the previous owner didn't even have a gasket installed between the cylinder - it was all gooped up with gasket maker. I've since cleaned that all up but found there are a few dowels missing - he only had two where there should have been four in two "layers" of the cylinder. Has anybody ever seen these left out before?

My best advice would be to completely clean out any of that gasket goop from that engine, even if it means splitting the cases (which I would probably do anyway just to be sure). If any of that goop or fragments of it gets into an oil passage, the engine will be toast. Then get it running properly in stock form before venturing into a modified bike. Get to know what you have and what you'd like to change first after riding it.

You may want to go through that engine carefully, looks like the PO didn't know what he was doing and makes me wonder what else he messed up!
