Hey fellas, recently just finished wiring in a brand new harness. Before I completed the wiring I wired the ignition etc. in just to get the bike running, it ran really well and I had it tuned, timed and carbs synced to almost perfect. Throttle response great even in the cold and all the way...

Hello, I recently aquired a 1979 XS650 SF with a points ignition system. The bike has no spark and while trying to diagnose it I decided to set the points. I watched a video on youtube () that shows how to set the points. Included in that link is a timestamp to where he uses a 12v test light to...

I have a 1981 Special, i had it running for a couple of weeks this summer with no issues, and all of a sudden while riding home from work the bike started surging and cutting in and out, with a weird sounding engine note. I tried giving it gas to keep it alive but it eventually died completely...

Hello, First of all, I am thankful for all the information I have already gotten from XS650 Forum and I plan to continue to support this site and be a good member. My name is Patrick and just got the bike I wanted 40 years. I love it. My plan is to get it reliable and keep it with historic...

Hey guys I have done a little more digging and found this diagram. Wanted to see if anyone had any thoughts on if it can be used for the 79 XS650SF year. This is a new engine to me and I have it as a donor engine to my old one. If it is stock can I use the new Pamco Electrical Ignition on...

Okay so here goes I am new to motorcycles and garage mechanics. My first real project and I’ve run into some electrical problems. I have removed the tach/speedo/light cluster from the bike with only cutting one ground wire, the rest were just unplugged. However my issue now is I have no electric...

Hey everybody. Just recently got my 1983 XS650 SH up and running again with the help of a local shop. Just put a new battery and regulator in but now I’m not seeing the charge I want. Battery started around 13.3 and went to just under (13.27/13.25) with everything off. Accessories on it went to...

This is my very first motorcycle project. I bought this aftermarket device for my turn signals, headlight, and horn control. It only has 8 wires while the original setup on my 1982 XS400s has 10 wires. However, they serve the same function (except the original blinker switch comes back to the...

Hey yall, I almost had this bike (81 xs stock) ready for the road, but recently it's been blowing the ignition fuse. On my numerous test rides up until recently it hasn't been an issue, but now it's eating through fuses and today I couldn't even get it started. The ignition fuse gets wicked hot...

hi guys, quick question hopefully somebody will know the answer to. Will the reserve lighting unit from a 1981 xs650 work as a replacment on a 1980 xs650? I would assume it should be the same but can anyone confirm this? The part number for the reserve unit on the 1980 is 1T3-84308-00-00. Thanks

There were 2 cabins each with own meter, one burned down the empty meter pan for that one is on the back side of existing cabin. I uncovered where the wires to feed non existent cabin are. I have a beautiful camper, where cabin was I have plastic box to extent wires to put a camper outlet but...

In shop class this year I decided on building a motorcycle. After shopping around here in Michigan I came up with a 1973 xs650 engine. The engine has great compression and looks to be in running condition. The motor is now in the frame but I have absolutely no electrical parts. I've looked...

Hows it going all, recently purchased a Pamco 277 igniton to replace my point model on my rephased 78 650. Was having timing issues and decided to upgrade to the Pamco. I installed the ignition using Hughes's guide. The problem I'm having is wiring to my coils. The wires coming out of the coils...

Hi so I finally got my bike charging after 4 months of trial and error. Installed a new Electro Sports 350reg/rec. The bike charges, however the voltage is high. At idle the voltage would range between 13-14V and when revved the voltage would go up to 15.9V. I decided to ride it a couple of...

After many years searching for an XS650 in Mexico in decent condition(they weren't originally sold here). I've finally found one thats close to where I live and in good condition. However it doesn't have an Alternator, I'm sure this question has been asked a thousand times but English being my...

Hey I am completing my 80 XS650 and I am adding a small push start button to the mix. My bike is bored out to the 707cc kit and I have had it kick back too many times for me to continue. Already have a bad leg and do not want to risk making it worse. I have modified a diagram that I have found...
