Hey I thought a tach would be neat for the heck of it.
Cant beat 12 dollars with shipping. I am praying it is electric and not mechanical. I looked at this tach and I swear I see a suzuki symbol on it.. It says suzuki tach but the 1977 enduro (when I google it) says yamaha.

Well I hope I lucked out because it looks very similar to my speedo and I hope to mount it on my bars next to my sigma bc1600. The tach also has a high beam indicator, turn signal thingy, and even a nuetral indicator. I hope to find these wires AFTER i determine if its an electric or mech tach. If its mech tach no big loss, ill ebay it back
