Replaced the sidestand. Way too much play with the old one.. probably about 3/4 inch play. Put a new one from Mike's on today. Play is about 3/16. Stud on the frame where the sidestand pivots is worn but can't figure an easy way to repair it, so will live with the improvement from the new...

How much original wiring was left on the bike?

I would say that the ground is connected to ground bus, but since you don't have a harness on the bike, then I don't know? The wire labeled for the horn will go to the horn. I assume there is a wire feeding the switch that will be connected to a 12 volt bus. This 12 volt feed will come...

Based on your description...yes. It switches to ground when in neutral.

On the SJ and SK models, the left and right blinking voltage go to the flasher indicator in the Pilot box. One signal drives one side of the bulb the other signal drives the other side of the bulb. This arrangement won't work with LEDs. It can cause some unpredictable results. maybe not the...

If you put in led signal lights, you will need a blinker unit appropriate for led lights as well as some possible changes to wiring.

So where were these melted wires? Are there components connected the melted wires that need to be checked or replaced. I assume this was the pma that got stressed, so are you still certain that the pma is working correctly?

You mention some wires that were brittle and corroded. How old was that installation of the pma? Normally it would take many years for wires to corrode. The wiring on my bike is over40 years old and not that bad. It seems more likely that what you saw was evidence of too much current going...

I replaced the boots on my 83 about 5 years ago. It fixed a lot of back fire popping issues at the time. Consider replacing the plugs covering the ports as well. At the time, I lucked out and bought a pair of boots at the local Yamaha dealer. They just happened to have a set in stock. They...

Yeh sure.

Meant to add a note about what I am working on. I ran my arduino tci all last summer. I hooked up my original tci module for the last few rides last fall. I concluded that the design was about 90 -95 % effective. Most of the time it worked flawlessly, but over the summer and accumulated...

Hi Adamc, When checking with strobelight, At rpms below 1900 the timing mark should stay near the firing mark on the chassis. There is no full advance mark on these bikes. I added one on my bike when I was doing my TCI testing and building. Still you should see it advance up to about 3400...

I think you should confirm that your test equipment is OK before proceeding with anymore electrical checks. 19.7 v is a bit unreal. If you can find another meter, great. Try checking a known voltage source, like a 9 volt battery. Keep in mind, that the typical cell voltage at rest, would be...

Well yes, it is after all called a diaphragm. So I am guessing it will be doing diaphragm type stuff. If the vent gets plugged, then you won't have the ambient air pressure on the top of the diaphragm. Probably works fine if there is plenty of fluid in the reservoir and gets worse as the...

I have been refurbishing the disk brakes on my 83 650sk. I ordered in a kit that had a replacement cap, metal plate(bush in the parts list), diaphragm and screws. To be honest I wasn't really needing a new cap, but I was comparing the old and replacement caps and noticed something. There is...

Finally got a response. I think the first two queries ended up in the bit bucket, but third time lucky. For anyone interested the email from them was XS650 <xs650direct@hotmail.com>

Hmm... I guess they just don't like customers asking pesky questions.

Did you get any other contact info.... phone number or email with your confirmation?

I have been trying to contact XS650Direct through their website contact form. Just have a couple of questions about the parts before I confirm my order. They are not answering. There is no other contact information listed. Not too impressed. If they don't respond to questions now, how are...

Well yes and no. I shouldn't have offered my efforts without thinking this through a bit more. I actually have a lot on my plate at the moment. I would like to see this project work. And I am curious to put one on the bench and test it, but I can't give it my full attention right away...
