74 street tracker

Quinn – I bought three non running basket case xs650’s for $1050 ( a 72, 74 and 79). I had owned and ridden bikes for years but never did any of the the work myself – these bikes changed all of that. The 74′ motor was shot but the 79 still kicked over. The problem was the 79 had a lot of back fees with the CA DMV. So I used the 74 frame and the transplanted the 79 motor. I bought the seat pan and the tank  (“750 Champion”) from Omars along with the rear hub assembly which allowed me to run the 19” wheel out back to match the front – both on Avon Roadriders.

I liked the look for the mags and for around $75 on ebay you really can’t go wrong.  Satin powder coat for the wheels and a lot of trim including the foot controls and gloss black on the frame.  I went with a PMA and Pamco setup, and completely rewired the bike from scratch (thanks to the guys who have posted simple wiring diagrams on the net).  Stock springs up from and progressives out back.

I road the bike for a while without getting into the motor but when it started to go south I took it to Gary Swan at Toad Town Racing (This guy has been racing and building Flat Trackers and race bikes for years!).  Not only does this bike now run amazing but he did it in a timely manner – thanks Gary!

Being my first build I can definitely say that it was a test of my fortitude and ability, but in the end well worth it!  I absolutely love riding this bike, and can’t wait to get started on the 72 that’s in the corner of the garage…

    Your bike is gorgeous!
    I just picked up an 81 special and plan on building pretty much the same bike. I got it for 900 and it is in excellent condition chrome and all so will be parting out stuff wont need. You mentioned the wiring on your bike which is one thing I’m going to have trouble with. Can you direct me to a place I can get a simplified drawing of how to do it? Also , in a few years I’m going to want motor rebuilt like you…obviously more power, I’d like the number of who did yours please, thanks

    That’s a great looking bike, love those 1970’s Yamaha graphics. Well done!

    Hey Glenn, I tried leaving info a few times but it keeps getting rejected – maybe because i included some links. Anyway just google XS650 wiring harnesses and you’ll find all kinds of diagrams online. It also will depend on if you are going to stay with the original points setup or go to a Pamco and PMA.

    Here’s Gary Swan’s info…

    Good luck!

    what kind of carbs are you running ? do you know what jets you have in them ? what setup do you have if you don’t mind me asking.

    I’m running Mikuni VM34mm Round Slide Carb Kit from 650 central. Not sure about the jetting – Michael pre-jets them for you. They work great!
