Last Sunday a few of us helped Mick sort out his SR’s wiring. The stock harness, in my opinion, is unnecessarily bulky with safety relays and switches. This inspired me to see if I could design something streamlined while still using the stock controls and dash gauge… this is what I came up with:
I found the stock diagram at the Philly Free Library. They have a decent selection of automotive and motorcycle manuals in their reference section. “Being a Yamaha owner, you obviously prefer a quality product”… These old shop manuals are awesome.

Canadian Rockies – day 10
White swan lake Alberta to Polebridge Montana Leave our campsite and go back to hot springs in the morning Met some cool girls from Portland Head back into America Do a 40 mile off road trail up and over a couple mountains, it was epic XR650L ripped Quinn’s Guzzi held up but front wheel didn’t […]
so… is it gonna work?
See if you can find any flaws in it but I am confident that this works… The Yamaha setup is a bit different than the Hondas so it was different than when we did your 650.
I can scan the OEM diagram and my diagram at work for a bigger high res copy.
looks good man. I think my next project is going to be a sr500, love these little thumpers.
i know of a sr500 for sale and a 1970 cl350 locally both running if anyone’s interested.
How much for the sr500?
I think he wants 1000 for it
damn! i need a 1000 dollars asap.
also a 1976 cb250 mint…i hooked up with a guy who lets me know when hes pickin up bikes of interest…i told him about chinonthetank and he’s always got bikes comin thru his shop.

chris how much for the 250? Title?
I’m looking to sell my 350 by spring, clean title.
ha, i got a 360 as well, curious about the 250 for my GF.
Mick, one of the copies I made front the Yamaha service manual has the introduction to the TCI unit which I bet has the procedure of how to test it but I don’t have copies of the following pages unless it’s on one of the sheets I left with you.
now i want an sr250 that thing is cool.
Good day will you be able to send me the simplified wiring diagram of the yamaha sr250 plz
