Hello, while I’m new to posting I am a veteran lurker.
I have previously owned a 79 but unfortunately had to sell. I now own a rather troublesome 81.
When I first bought the bike it was completely stock apart from the missing battery box.
The original ignition black box was shot so I fiddled...
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...
Hi All,
I have an 1981 XS 650 that while riding this summer stopped running suddenly midride. At the time, I'd tested it and confirmed that I was getting no spark when grounding the plugs to the engine. I'm finally getting around to trying to fix it.
Not sure if these details matter but im...
This is my first post on this forum, but I have been looking at a bunch of other threads for ideas. But haven't really come across anything that matches my problems.
So, I picked up a 1979 special. When I got the bike it ran, but rough, it sounded like an ignition problem and I decided to...
So I'm working on my buddies '75 xs650.
He has no spark, yep I know another one.
So I sanded the points clean with 1200 grit. Pulled the plugs and no spark. Removed the plugs from the boot and put in a screwdriver, no arc to jugs.
Voltage on battery with charger is 12.5. tested kill switch it...
Recently added a 1975 XS with a side hack to my stable. Bike sat for 10 years, in a garage. It's in pretty good shape, no corrosion, altogether pretty clean. I plan on taking it apart, cleaning it up, replacing whatever I need to replace and reassembling. Have decent compression, wiring is in...
Hi folks,
I've been reading through the threads for a couple of weeks trying to advance my backyard mechanic skills but might be in a little over my head lol. I bought an 82 xs but don't think I'm getting spark. It looks like the PO changed the charging system to a PMA and the ignition looks...
I have a 1980 xs650 project that I received about half completed. I wanted to verify spark before I continue to build. The bike has not run in over 3 years. I have videos of it running from the seller. It has the tcbros 6 pin harness and i am mocking up a very simplified harness for testing...
1981 XS650 SH with a Pamco ignition with Eadvance. 2009 tag on the board so I'm pretty sure it's a legit Pamco.
I'm trying to diagnose a no spark situation I got myself into. I was troubleshooting a charging system issue, jumped the Reg/Rec, and let it run a few seconds too long. I saw ~16.5V...
So, I just finished putting a build together of an 81' xs650. Had it running today to sync the carbs then took it for an 8 mile ride and it rode and sounded great. I'm running a PMA and the XSCharge electronic ignition. Here the ignition I'm running...
This is what the ignition looks...
Hey everyone I'm new here so bare with me...
So, I got this crazy idea a couple months ago that I wanted to build a bobber out of a xs650 even though I had no prior experience working on motorcycles but plenty with working on cars and I consider myself an easy learner when it comes to...
SOOO guys here I am again with complications. I had my 77 xs650 running fine. So, I took off the tank, rear fender, and side panels and painted them.....didn't touch the bike once in that process. I put everything back together and the timing is off this time, misfires and what not. I shut it...
ok so I am looking for a little help here to help out a good friend with his firs xs. hes getting very discouraged. he bought a titled roller and then an engine from another guy who said it ran. well we have yet to determine that as it has no spark, hes gone through the install of the pamco...
I b
I have Isolated the ignition circuit and unplugged the charging system .I Used a test light to try and feel like I did something right as voltmeter reading were less than a volt. This is debatebly inconclusive though because my volt meter did not react to key switch changes and my test...
Hi guys, iv recently pulled my 83 xs650 back into the garage and pulled out all my bins of parts. It's been a few years but I finally have some time to fool arround in the garage again!
Anyway I'm having a very huge problem and would really appreciate some help here from you awesome guys...
Hello all, recently acquired a 1980 650 Special to add to my collection.
Previous owner says they replaced some gaskets and then could not get bike to start.
They then put the bike on the "back burner" so to speak and I bought it complete for $200 a few days ago. They think the timing is off...
Hi everyone,
I've owned my 79 XS650 for about 10 yrs now. It has always been good to me and never left me stranded. After many miles of riding, it finally died on me. It was running fine and I shut it off at a parking lot for maybe 15 minutes. During this time, the key was removed (ignition...
Yo, I have a 1980 xs650 that I've been stripping down the stock bits. This morning I changed my burned out tail light bulb and wired my neutral light to my new mikesxs mini speedo. It was idling pretty normal with a full tank of gas, I rode about 5-10 minutes down the road and as i was changed...
I have a 79 650 special. It just died, It smelled like something was hot or burnt but I couldn't pin point what. After pushing it 1/4 mile home the smell wasn't as strong. It has no spark on either side. The fuses are good, the battery is charged, no pinched wires. Does anybody have any ideas. I...
Ok, so the other day I went to take my bike out. It was running fine, I went to fill up and and continue my ride. With a full tank of gas, about a thousand feet away from the station, my bike just shuts off. I've notices a slight issue with my gass cap, it's vented, but not venting properly. So...
