Partzilla Live Q&A with John Talley 08-13-21

Honda Motorcycle Repair

Have you any recommendations for an 06 Honda CBR600RR that has regulator-rectifier problems being next to the head and down where the pipes are getting too hot?

John Talley: If I remember correctly, the regulator-rectifier is up close in between the pipes. And if your pipes are getting so hot that they’re affecting it, I would probably recommend doing a wrap on the pipes that would actually hold the heat in. That’s actually what most racers are after, and so they hold the heat in and force it out the back. … As long as they’re titanium pipes, it’s not a problem. If they’re anything other than titanium and they get wet, well they’re going to rust. But more than likely they are titanium so if you want to keep heat away from that CDI, you may want to consider wrapping the pipes. But it shouldn’t have an issue. I mean Honda would’ve moved it if that was going to be a big problem and we’d burn up more of them. Maybe you have a different exhaust now and maybe it’s not holding the heat in as well as the factory head pipes.    

I have a Honda Monkey 125. Where can I tap to get switched 12VDC for my Garmin GPS?

John Talley: On that one you can probably just come off the actual ignition switch itself. That Garmin is going to pull such a small amount of current. I don’t think it’ll have any problem doing it, although if you’re going to do a t-tap into it, I would try to make it watertight. And I would also add a fuse at that location going in between where you’re going to tap in at the switch itself and your Garmin. We tapped into our Grom build and we added in a display. It was a cosy display that we added to it, so if you would, reference that video for the Grom build and it’s going to be very similar to that 125 Monkey. And it probably even has the same color code. Look where I added that little display on it and see where I tapped into it. 

Honda ATV Repair

I have a 400 EX and I put a rear carrier assembly in already assembled. I bought two and every time we would go to tighten the caliper, the rear end would lock. Any thoughts?

John Talley: I’m not exactly sure what you’re telling me there. So you replaced the bearing carrier and now every time you go to tighten the caliper the rear end locks. Alright, check the actual parking brake. There’s actually a screw in and a lever on the back side of the caliper if I remember correctly. And if that’s too tight as you’re adjusting it, it’ll inadvertently pull that cable and put on the parking brake, so loosen that up and see if you can get it to spin freely as you’re adjusting it. 

I have a 2004 Honda Rancher 350 ES that I haven’t ridden in a while. I changed the carburetor and it started up just fine and then shut off. Now the reverse and neutral lights are on. What could be the problem?

John Talley: Alright, as far as the starting up and just shutting off, it makes me wonder if maybe you have a fuel supply problem. Because if you replaced the carb that tells me it was in really bad shape because it stayed stationary for a long period of time. So more than likely, above the petcock over on the left side if I remember correctly, it goes up inside of the fuel tank and there’s actually a very small screen filter. And I bet you that’s probably gunked up and it’s probably not letting fuel get down to your carburetor and fill it up so it’ll run. As far as the reverse and neutral lights both being on, I’m wondering if you may have inadvertently plugged or unplugged one of the neutral indicator wires or the reverse indicator wire. Because I think that reverse is actually down toward the bottom of the engine toward the back. So when you were removing the carburetor, you possibly pulled it off and then it went to ground. Just a long shot there but I think you’re dealing with two separate issues. One being the carburetor not getting fuel and then maybe a potential wiring problem that came up due to shifting things around when getting that new carburetor put in.
