ignition

More of a survey, really. Hello, all. I am a new member but have been a fan of this forum for quite a while. I recently acquired a rather poorly treated '78 xs650sf2. I have in mind a future post that will be more descriptive of the bike as well as properly introducing myself. As the xs is...

Fellow XS’ers! First off, thank you again for the warm welcome the other day. Nice to know there’s a place for people like us. ‘Voor elke gek, een plek!’ 🤪 Like the saying in Dutch goes. I’ve been puzzling over something for days and can’t figure out the best approach. So, once again, I return...

I've got a 73 tx650 that I need to fix the starter on. The current problem is the lever pulls but with no resistance, as if the kill switch is in the wrong position. This was rather sudden as I had been test riding it for about 5 miles before this happened. When I got it back to the house I...

Hey Friends, Due to an injury, my 81 XS650 Sat partially assembled for 15 years. For the past few months I’ve gotten her ready to go but for one thing….she won’t start. Holding the plug to the engine case produces one fairly strong spark each time I push the starter button, then no spark. Tried...

Hi all, I just recently picked up a super clean 1980 XS650 special II and am planning to replace the carbs ignition/ charging system and simplify the bike as much as possible. I have already learned a lot from this forum about the aftermarket carb kits and the ignition/ charging (sounds like it...

Hey y’all. Just bought this 79 xs650 from a friend for a couple hundred dollars. Forgive my ignorance this is the first motorcycle I’ve truly worked on. After getting a new battery I kick started it and got it to run while giving it gas, although it seemed to be only left cylinder. Now it won’t...

Scratching my head here, I’ve got an xs650 with a Hugh’s cdi ignition the previous owner put on. It seems like the timing is a bit too advanced, how exactly do I retard the timing on this setup. Every thread just explains finding tdc with the damn sticker. Nothing about actually adjusting the...

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...

Hi XS650 fans, I am new here but i ran out of search options on google. I have 1892 XS650 that i bought as a barn find. This is my first xs650 so there is some learning curve for me. I have two manuals and both say that i have to remove the ignition advance unit, the rod and so on. I want to do...

First off, I’ve been lurking and learning a ton from this forum. I was a Harley guy but have turned toward parallel twins like old triumphs and now the xs650. Brand new build 1979 XS. HHB charging system and capacitor, mikes xscharge ignition, new advance everything, new rod, new wiring...

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...

Hey fellows, this may seem like an amateur question but I can’t figure out what this disconnected thing is attached to my top engine mount. Any ideas? Cheers!

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...

Hey guys I have a 81 xs650 kickstart. Have PMA, original points. But now replaced the regulator, capacitor, switched to mikexs ignition gen 2 and new dual output coil. I can't get this bike to start. Got it from craigslist dude lied and said it needed one thing. I can't find a wiring diagram to...

Ordered this and never used it. Ended up ordering a whole new vape ignition set. Retail: $41.97 + shipping. Ignition Coil - 1.6 Ohm - High Output - TCI ignition SKU: 17-6803 from Mikesxs https://www.mikesxs.net/yamaha-xs650-high-perf-dual-output-ignition-coil-oem-3g1-82310-60.html OBO +...

Hello, I am working on an 81 XS650H for a friend. For a bit of backstory, it originally had pod filters and bad float needles. So, we found the original airbox, looks to be in good shape and new OEM filters and new OEM float needle assemblies (the entire assembly including the o-ring, not...

Hey all. My mechanic used a different ignition than I supplied him on my 277 rephase rebuild, does anyone know what the make is? Have attached a coupe pics. It connects to a little black box with two coloured LEDs on it, wiring is done and fairly straight forwards but still be nice to know a...

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...

Hey all. I was just wondering if the hughs handbuilt pma and electronic ignition would be a good choice compared to the vape ignition and pma kit. What are your thoughts? Also cutting and re welding the camshaft or grinding and rewelding them up. Opinions? Also, no offence to Hugh. Im just...
