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.
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.
picked up the multi-meter.
what should i be testing in the ignitor unit? that all connections hold current?
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
