I have a 1976 DT400 with a trashed engine. I have a 1977 DT400 Engine.
I want to swap engines so I can ride and rebuild the bad engine over next winter.
Yamaha changed a bunch of stuff on these engines starting with 1977. THe exhaust is on the oppisite side which makes the fins on the head different. Other changes are to the clutch and cable routings/hookups. All this is stuff I can deal with.
Does anyone know if the engine mount spacing, electrical, front sprocket spacing, or anything else was changed which prohibits this being a bolt in swap? It would be great if I am able to do a engine swap and go ride.
Thanks in advance
