    Gas cap seal while cleaning a tank

    Yes, the vent leaks and it's also a super old gasket. I should have checked this thread and used your idea of extra pieces of rubber. In the mean time I used Ichiban's suggestions of the expanding plug and added some Thermal Adhesive Plasma to seal up the notches. It's working for now, but I'll...

    Gas cap seal while cleaning a tank

    Thanks guys... great tips. Would the expanding plumbers plug work on a tank opening that has the two notches?

    Gas cap seal while cleaning a tank

    I’m working on two nastily rusted tanks from a ‘75 CB125 and a ‘81 CM200t. Both were super rusted but I’ve gotten the bulk of it removed with a combo of vinegar, bolts/nuts, lots of shaking and some experiments with electrolysis. I’m now about to do a final bath in evaporust and start the...

    Full disclosure... I broke one of the sleeves/guides during disassembly so I’m deciding if it really needs to be replaced. I was actually thinking about removing it anyways to avoid future rust, but please tell me if you think it needs to be there. Also, this whole spring section gets covered by...

    These forks are of the external spring variety. If you look at any stanchion from this era on eBay you will see this 4” area in the middle that is rusted. Mine were super rusted until I scrubbed on it for way too long. It happens under this plastic sleeve called the “fork spring guide”. I have...

    I forgot to take a “before” picture but these forks were in super bad shape. Everything has some degree of rust on it. It took an act of god to get them off the bike. I then took them apart and dipped most of the parts in evapo-rust. After lots of scrubbing they are starting to shape up.

    Front brake calipers are cleaned, oiled, and rebuilt. I also cleaned and re-oiled the cable. I’m trying to reuse anything not overly broken on this bike. I actually think this brake cable is one of the few things not original on the bike, but it was there when I got it, so that counts. Repairing...

    I ended up finding a product that was perfect for fixing old (non-critical) gaskets. It stays pliable and seems to have done the trick.

    I hear you Maritime and that’s in the extended plan. However, for now I’m sticking with what I got. Is it plausible to use a little “gasket maker” right where the tear happened? It’s a clean tear, no missing material. Sent from my iPhone using DO THE TON

    1975 Honda CB125S and 1981 CM200T

    Now I’m working on the front. I’m going to rebuild the forks and clean up the rim. It has this kinda funky manual disk brake. I took it apart to clean it as well. In the process I tore the paper gasket. It appears this gasket is no longer available. What’s the best way to repair this? It’s not...

    1975 Honda CB125S and 1981 CM200T

    A lot of work has been done on the ‘75 CB125, but you’d never know it by looking at it. Mostly because work was done but not much accomplished. Frustrations were high because I could not figure out why it was running so rough and so rich. I rebuilt/cleaned the carb twice. Triple checked the air...

    Long time since an update and in the mean time... the world has changed! I hope everyone is safe and healthy. I know we’re all going through some tough times. Thank god I have an old motorcycle to work on to clear my mind from our situation. I hope each of you have the similar or another outlet...

    Nice work, it looks really sharp. Did you put the rear shocks on? What kind are they and how do the feel? I'm working on my first build as well and don't want or have the budget to buy expensive shocks, but don't want crap either.

    Those look great! Do the indicators from Amazon look the same? Where did the tail lights come from?

    Choke was open and I'll check the main jet sooner than later. In the video, the engine was not warm, but this weekend I let it get run for a good 10 or 15 minutes before adjusting the air screw to try to lean it out. The (new) spark plug was super black which is why I was thinking it was running...

    By the way, thanks for all the tips and suggestions. I’m taking them all in even if I don’t directly respond. I really appreciate it.

    Fuel is going directly into the carb currently and seems to flow fine. No tank or petcock currently to worry about. When assembling the float, I adjusted it to spec, 24mm I think. It was at 21mm before adjusting... way off. I too was thinking the main jet may have an issue but I want to make...

    I also checked the ignition coil. I could not find the specs for it anywhere online. I did find an aftermarket coil with specs, but my results were very different. The primary circuit read. 2.0 ohms The spark circuit read 23.4K ohms Does anyone know if these show the coil needs to be...

    That video was from last week. This weekend I worked on getting the air mix better because it was running very rich. Still needs work but I leaned it out some. It idles great and now starts up with easiest of kicks. However, anything above idle causes it to run super rough. I assumed it was the...
