    [1982 Honda CB125S] Nearly completed LED 12v light conversion but cannot figure out this issue. (SUCCESS!)

    Yes it feels good especially because I wanted to sort this LED stuff out before completing the bike. I now can sort out the aesthetics, install some new parts I got, and get new tires etc. Gettin' there...

    [1982 Honda CB125S] Nearly completed LED 12v light conversion but cannot figure out this issue. (SUCCESS!)

    Thank you Teazer and thank you Benroloff. Those are both great explanations but I must admit that Benroloff's explanation made sense in my mind's eye. Sorry for the lack of update, I am also trying to bring back to life a 1985 RX7 FB and recently pulled the intake/carb on that and now am doing...

    [1982 Honda CB125S] Nearly completed LED 12v light conversion but cannot figure out this issue. (SUCCESS!)

    Please forgive me, I am an extremely visual learner bordering on disability so I need to try and visualize this via the wiring diagram. Is this a correct interpretation of what you're saying I should do : Describing the image above : I keep the black wire coming from the blue indicator bulb...

    [1982 Honda CB125S] Nearly completed LED 12v light conversion but cannot figure out this issue. (SUCCESS!)

    Okay I am embarrassed to say that the original wiring diagram with the explanation of how I wired in the diode was incorrect I had my wires mixed up (but according to the video it shouldn't matter). This is the correct wiring diagram and how it was done, the only difference is that I wired the...

    [1982 Honda CB125S] Nearly completed LED 12v light conversion but cannot figure out this issue. (SUCCESS!)

    I will get pictures tonight. The LED strip is causing confusion, it is not installed I am using the OEM lights right now. I only connected the LED strip as a test because I wondered if the rear brake light bulb was the cause. I wondered if maybe the LED strip had some diode in it or would...

    [1982 Honda CB125S] Nearly completed LED 12v light conversion but cannot figure out this issue. (SUCCESS!)

    Hmmm I don't think the previous owner messed up the wires, it all looks very OEM. This bike I have completely rebuilt down to the frame so I am familiar with the placement of the wires and the diagram but don't fully understand the concepts behind how it all works on a higher level. I have one...

    [1982 Honda CB125S] Nearly completed LED 12v light conversion but cannot figure out this issue. (SUCCESS!)

    Hi everyone, So I can confirm that if I remove the dash bulb and try using the turning signals I get the exact same result; the rear stop light flashes and the right turning signals stay off. I forgot to disconnect the left side and see if right side works instead so apologies for that but I did...

    [1982 Honda CB125S] Nearly completed LED 12v light conversion but cannot figure out this issue. (SUCCESS!)

    Hello folks thanks for the replies that is much appreciated. I used a pre-made diode kit that is meant for this and followed the exact instructions from this video : I know 100% I did not splice into the rear light wiring. The rear light has 3 wires, one for the brake light switch (green...

    [1982 Honda CB125S] Nearly completed LED 12v light conversion but cannot figure out this issue. (SUCCESS!)

    Hello everyone, Hopefully people with good electrical knowledge can help out. I have a 1982 Honda CB125s and it came with a 6V system. I am trying to complete a 12v conversion but ran into an issue with the turning signals. The bike has a 12v front light, 12v battery, 12v rectifier regulator...

    [1982 Honda CB125s]Camchain tightening procedure - need advice

    Okay I think I have the final piece of info I need now. So we can disregard the videos I posted above re: sound. Most of those bikes are out of spec too. I contacted someone I knew had a lot of experience with CB125s as he has been selling 125cc bikes in the UK for over 30 years and has...

    [1982 Honda CB125s]Camchain tightening procedure - need advice

    Hmmm I think you missed my latest reply but yeah it had no effect. I'm now wondering if I'm crazy and the sound is normal or w/e idk. I went looking on youtube for 1981/82 CB125S idle sounds and some sound very thumpy with a lower speed idle of like 1000-1100 and this one at 1300 or so idle...

    [1982 Honda CB125s]Camchain tightening procedure - need advice

    Okay so I am at a loss. I took off the covers on the alternator side and inspected it and took some photos to show you what I can see. It appears I have the same cam chain tensioner as in the video from my first post. I did my best to get the light in there: https://imgur.com/a/GwolWrk So I...

    [1982 Honda CB125s]Camchain tightening procedure - need advice

    Just to make sure I don't newb out and screw it all up. I assume by crank bolt you mean this bolt here right ? (Not my engine just a pic from the internet) https://imgur.com/a/N7ZZFvr

    [1982 Honda CB125s]Camchain tightening procedure - need advice

    CoffeeGuy, I did not...I only followed the clymer manual instructions which doesn't require you to remove the cover or keep torque on the crank bolt. I thought I would get lucky but you're right I need to do it again and remove the cover to see if I have actually adjusted anything. I was weary...

    [1982 Honda CB125s]Camchain tightening procedure - need advice

    Hi everyone, Okay so on Sunday I got to the bike, unscrewed the top cap of the adjuster nut and tried to use a screwdriver to push the mechanism down. It wasn't budging and I felt like if I pushed any harder I might do some damage so I decided to leave it. Unsure if it is stuck.... I then...

    [1982 Honda CB125s]Camchain tightening procedure - need advice

    Thank you trek97 and jpmobius, I greatly appreciate the replies. Trek, that's a cheap piece so that's definitely an option. Since I posted a friend of mine has given me a tach but I had no idea how to install it and was beginning to look into that. I think I'll be good with your instructions...

    [1982 Honda CB125s]Camchain tightening procedure - need advice

    Hmmm well I wasn't able to get some advice elsewhere or here which is fine so I guess I will attempt to adjust it by ear. I figured it would be horribly inaccurate but I have no hope of installing a tach so I will find the best youtube vid of a similar bike idling at 1300 and try to match it...

    [1982 Honda CB125s]Camchain tightening procedure - need advice

    Hi to all, I have a CB125s and recently while riding I noticed a lot of noise coming from the head and determined that the cam chain might be a bit loose causing the sound. I know the valves are alright as those were tightened to spec recently. I have a Clymer manual and it specifically...
