1975 stock XS650B. Had the bike in storage a number of months. Came back to it today and found brake fluid pooled along the wheel rim and some had dripped down onto the tire. I wiped it up, and noticed a trail coming down the rotor and from where the metal brake pipe meets the caliper. that...

Pardon the delay — I had a lot of work this week, and I ordered a new right hand control. I wanted to replace the right hand control anyway, as the original one was beat up. I found a really clean NOS control on eBay. Thought I would install it as I did my troubleshooting. So first I installed...

5Twins — if it’s the button itself, does power flow through it as the bike runs? I ask because the dying issue also happens when kickstarted. If the power does in fact all go through that right control, no matter how the bike is started, and it would cause the bike to sputter, this hopefully may...

XSLeo — I just put in a brand new battery and it still did the same thing. The alternator brushes are about a year old. Stator coils in good order. The aftermarket solid-state regulator/rectifier is about 5 years old. If the regulator/rectifier went bad, would it cause the starter button to not...

1975 XS650. Fully stock head-to-toe, except a Pamco + e-advancer, and a solid-state regulator/rectifier. Last year, I had this weird issue where every once in a blue moon the starter button wouldn’t work. I would push it, and either absolutely nothing happened, or I would hear a click. So I...

The hidden nut behind the bolt doesn't spin, it's a welded part attached to the battery box. I tried four different methods to try to get the bolt out -- Flathead screwdriver under the head of the bolt: I had to really dig to get it in there, the screwdriver is under the washer. I pried...

On my stock '75 XS650, a bolt is stuck but spinning freely. It's the lower bolt that the left airbox mounts to the battery box. This means I cannot remove the left airbox, which makes removing the left carb nearly impossible. The thing is, that spot is very awkward. The rear of the bolt isn't...

Update: Installed the new dual-output coil, and the Pamco with E-advance, what a great product. As for carb sync, I just found out about a product called the Edelbrock Uni-Syn. This is a video of a guy using it on a Suzuki: Video. Basically, it takes carb pressure readings on the intake side...

I have just bought the Pamco system, it's in the mail. I'll use the dead cylinder method with a grounded spare spark plug for now. The Dogbunny sync method "by feel" is interesting. I don't know how accurate my hands will be but I'll give it a shot. I haven't found barbed intake-side boots. I...

Hello, I have a stock 1975 XS650B. The points are finally getting to me. I'm thinking about getting a Pamco electronic ignition. According to the Pamco website, it says the ignition requires a special dual-output ignition coil. Here's a link to it. So here's the issue. The BS38 carbs on...

Upon taking apart the high/low beam switch, I saw some green, powdery residue and some brown rust-looking residue on all of the flat contacts, and some dirt on the little round pointy contacts from the switch. I cleaned all of them with fine 800-grit sandpaper, and wiped with electrical...

I thought there was a frayed wire somewhere. So I checked the continuity on the blue/black wire to the little blob of solder by the switch, it was fine. The green wire was fine too. The yellow was fine as well. But when I tested the blue/black on the end of the wire to the green or yellow --...

Update: finally had a chance to work on the bike again today. Checked the voltage on the blue/black male connector from the left control that linked to the female blue/black from the left main wiring harness -- no juice at all with the right headlight switch set to On. (I could tell the on/off...

TwoManyXS1Bs -- I will check that next thing. But I'm still at a loss about the horn and the hi-beam indicator. Now, I have an idea to temporarily rig the headlight by wiring it directly to the battery with long wires until I get the rest of the wiring sorted, would it damage anything by doing...

Hello again 5twins! No, I did not remove any RLU, I don't think my bike year has one.
