I have decided to build my own bike with parts I can get cheap, first thing I need to do if figure out what this engine is, I have kinda pegged it as an R1 but can't figure out what year it is. It has 348cc molded into it and the engine ID# is R1-09409.

Thanks Merv, This is the one that i offered up to the guy wanting the modern R1 engine, Haha. After lookin into it I think I'm going to go ahead and put it on the bike anyway, just looking to get some info on it so I know what parts to get...

Here you go, i'm not saying your motor is 1967 but this link will take you to a picture of one, a 1967 (Y)R1 350

Yamaha R1 350

I'd be looking at what its worth first. Even wrecked i bet it would pay for a far better motor to build a bike round. It will cost a packet to do up as well, everything will be expensive.

Crikey DT175 parts are getting tricky to drag up and they are like belly button fluff compared to these.
