Anyone else out there realize the manual in the title has an error in the wiring diagram for the RD350?  Manual shows the GRAY wire going to the LEFT coil and the ORANGE wire going to the RIGHT coil when in fact it's the opposite.  In hindsight the diagram could be considered correct as the LEFT coil could seen as actually being on the RIGHT side of the motorcycle by placement in the diagram and vice versa, they are just labeled incorrectly.  It makes sense as back then the manuals were written by Japanese and not proof-read by English speakers, or so I've been told.

Thought I'd share and hopefully save someone else the hassle of finding out the hard way.  My friend always said the Japanese did it correct, as in the right point looking at the generator was for the right cylinder and the left point was for the left cylinder.  That's when I realized the bike had been wired wrong at some time.
