    pidjones '72 T150V rescue

    That's a lot of gear whine which is presumably the straight cut timing gears. Unusually loud - but that could just be the frequency caught on the phone or camera. Sounds like it's running on two cylinders at the end which might explain the rough sound. It should tickover much better than that...

    That's great news. Congrats. Now go and enjoy riding it and stay safe.

    Vintage forks with progressive springs, still not enough

    "Oh the front will never overcome the power of the less rear sag." You are correct that if one end is wrong, tweaking the other end won't fix it. Maybe I should have explained that better. Assuming that the rear end is close to being right, that test I suggested gives a good idea as to...

    Vintage forks with progressive springs, still not enough

    Irk hit the nail on the head. Either the springs are too soft or the sag is too small - or both. Ticker oil and more oil will increase the resistance to bottoming out but check sag first and then add a spacer or try springs with a stiffer rate. I suspect that a longer spacer might be enough to...

    The biggest problem with reading plugs is understanding what it's all about. First thing to keep in mind is that plugs get hotter under load. Sounds obvious but what we are reading is really how hot the plug got. At low load a plug tip might be around 200-300 degrees C and at full load it...

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

    For some reason, the Imgur links don't work for me, so I can't grab your image and modify it. So let's try with words and see if that works. They say a picture is worth a thousand words, so get ready for a thousand or so words. :-) I think that most of us have difficulty understanding...

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

    Looks like you added the diode wires to the existing wiring. You must cut both leads to the indicator bulb. the two wires from the bulb, one goes to the diode and the other to ground. Then connect the two cut wires to the diode kit wires. You should not need to splice anything in to the...

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

    Two questions: Did you cut the two wires to the indicator bulb? Are you 110% sure that the LED strip is correctly wired into the main harness?

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

    I understand why you are confused because it sounds like to did what was required and yet clearly the brake light is flashing when you try to indicate Right and that's confirmed by the fact that removing the rear bulb stops the flash at the rear but the right indicators still don't flash. We...

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

    Interesting solution. The issue is that in a conventional setup the idiot light is connected to both sides. With old school light bulbs that's not a problem because of the current draw and the time it takes to light the bulb, but with LEDs it basically makes both sides flash together. The...

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

    Lots of bikes from that era had the single idiot light and with LED indicators, the power goes to one indicator and also though the light to the other side. That's where the diode kit comes into play. https://pinkpossum.com/Lights.htm but I'm sure that if you bought a kit from SparkMoto, then...

    Good choice of tank. Here's one on the CB160 I built.

    1980 Yamaha SR250 Worn Camshaft & Rockers

    Is that needle roller bearing as bad as it looks? Should be replaced.

    Looks great. Shudder you say. That's unusual. I wonder if the clutch hub cush rubbers are shot and allow it to cycle back and forth. Are there rubbers in the rear wheel as well? If so they may need to be changed out. It might also be a drive chain snatch effect as the power is fed in. Try...

    1980 Yamaha SR250 Worn Camshaft & Rockers

    Looks like the fix was to restrict oil to the crank in order to allow more oil to flow to the top end. on the wrecked motor, what do the cam bearings and the surfaces in the head look like? Honda used to have a similar problem with some of their singles and many early 4 cylinder bikes and...

    1980 Yamaha SR250 Worn Camshaft & Rockers

    Hi MotoMike and welcome. That rocker is well worn to be sure and that means the cam and rockers have to be replaced at least. And possibly the head if the cam has picked up on the bearing surfaces. There are two ways you could go. One is to try to work out what went wrong on the low mile...

    Ton up SR250: 100mph, 100kg, 30hp

    It helps to "port" the fuel tap and the area of the carb above the needle valve and to fit a larger needle valve if one is available. And try it without the quick disconnect just to make sure thee are no fuel flow restrictions. You can also dill a slightly larger breather hole in the filler...

    With the dipstick, don't screw it in to check oil level, just rest it on the case. It's hard to tell from the picture and video but some of the dogs look to be worn. Run it through the gears with the cases open and see if you can better determine the source of the noise. If a shift fork is...

    1975 Yamaha RD350(LC) Preservation-mod Hellride

    Good news is that it's not hard to fix. bad news is that the motor has to come out and be stripped. It does sound like the double row bearing has collapsed or the inner cage is split, but it has to come apart to change it and to see what's wrong.
