    "Poor Kid" 1981 CB750K - first build

    Re: "Poor Kid" 1981 CB750K - first build I hope I can say I've gotten a little calmer and a lot less twatty in the past few years. Looking at the above kind of cements how I regard that time- pretty frustrating! Happily married and up in WA now, living in Auburn area. I grabbed a...

    "Poor Kid" 1981 CB750K - first build

    For anyone who gives a shit, the CX500 is my next target and will not be so frustrating. 'Don't give up' is a fucking puke of a statement- do undertake projects you haven't the energy to complete, be it resources or time. I can't wait to attack the CX (much less of an uphill struggle) and do...

    1981 CB750K project for sale: Fort Worth, TX Hello all! This thing is ready to be sold. I used it as a chemistry set and all the minor 'fuck-upgrades' are trivial to me. I'm not taking it back apart. Who wants it for $700 cash? Local is best, I don't care to hear your admonishments or your...

    After a few weeks of looking like a simian gaining carnal knowledge of a certain hard-husked tropical food, I figured out the bulb is indeed... Dead All connections test fine cap'n, thanks to old work by a DTT local and new work by myself. Gotta get on amazon and grab a bulb, and a brake...

    "Poor Kid" 1981 CB750K - first build

    I'm thinking it must be a ground on one of three or so wires. I'm pretty bad with the multimeter and it shows. I feel like I will end up clipping all the controls after looking at the piss-poor solder job I did. Such a little gremlin! I was just about to take it to work and do some fab, but now...

    "Poor Kid" 1981 CB750K - first build

    Will do. Got a bit distracted today. The leak of brake fluid destroyed the electrical switch beneath the master cyl. Also, my headlight still doesn't work. I had only taped up a few components, now it and the control don't work. Weird! The bike still runs and all just no headlight or light...

    got it all fixed up, i thought, just reassembled the bastard and flushed fluid, then bled it. it was a little spongy still but i took it for a ride and died out for fuel starvation. it's been a constant battle to keep these carbs fed, but a little bit more modding should have it just fine. I...

    Ugh I'll just reassemble the caliper, I don't know why I'm dicking around!

    "Poor Kid" 1981 CB750K - first build

    Bike reassembled and running after all the little boo boos. Kinda poppy and backfirey when it's cold, but well enough. My starter is dead, or near it- gotta find one soon. That brake is still dragging. I malleted it and tried to free it but I couldn't figure out what was bound. Maybe a stuck...

    "Poor Kid" 1981 CB750K - first build

    you know, it wasn't quite a drop. I don't honestly think it could have damaged the rotor. maybe the pads are just rubbing for no reason, eh? I'd be happy to try out the non-replacement fixes anyone can dream up. Otherwise I might be trading a firstborn...

    Also I dropped this thing while pushing it home one shitty day. I'm pretty certain I bent or damaged the front rotor because it will hum while pushing it slightly... Coming from the rotor. are there common sense solutions like having it turned on a lathe or am I about to look for a new rotors...

    Okay everyone. The bike, which was at a friends house, is now home and I'm working on it today. Before I do any repairs, I need to send the poor starter motor out to pasture. Little guy spins out more than 60% of the time, likely due to my first and POs last poor starts. Rich, you once said you...

    I'm very whelmed by all this. Not over or under, just regular whelmed. I knew there were more challenges! So... Now that the science and reasoning are clearly outlined above, can y'all help me make a to-do list? Step one: compression Step two: valve clearance, Etc! I'm trying to figure out...

    "Poor Kid" 1981 CB750K - first build

    I've read extensively through the Factory Pro carb tuning pages, but I haven't checked valve clearance at all, nor compression. The bike is running well enough but isn't legal or near a dead street, so I may need to move it closer to my home in the country if I want to try plug chops. Really...

    Wow, huge write up, chuck! I'll try to respond to you tonight when I get to read through this. I'm at work currently. Maybe I'll document my carb settings as of now to see how much things change as well... Few hours
