    Another Fork Seal thread - 1981 CB750K DOHC

    I've had some bad luck with one of my fork seals consistently leaking and wanted to get the opinion of others. Take a look at the following pictures and please let me know if anything obvious stands out that could potentially cause a fork to leak: I feel like the problem likely has to do with...

    What can I do about this bolt that is causing an oil leak.

    Scratch that. The bolt threads are completely messed up which is the result of the nut being messed up. Anyone know of a part number for this bolt?

    What can I do about this bolt that is causing an oil leak.

    Please close. Nut ended up not having any threads left in it. cut off the nut carefully and replaced it and problem solved!

    What can I do about this bolt that is causing an oil leak.

    So I have a bolt on the exhaust side of my engine just in the front that appears to add some clapping pressure to the gasket between the cylinder and the bottom casing of the engine. My only problem is that I can't get this bolt to tighten therefore I've got a rather decent oil leaking going on...

    High idle at operating temp when clutch is engaged?

    so I'm in the process of test riding my 1981 cb750k every other day because I've just recently completed a rebuild on it and have run into a bit of a running issue and I wanted to run it by some of you. So to break down my current set up, I have 4-1 aftermarket MAC exhaust with a baffle in it...

    Engine reassembly question "1,4T"

    next problem. In an attempt to install the exhaust cam, the manual says to take off the exhaust camshaft sprocket and place the sprocket under the exhaust chain and feed the camshaft through but I can't seem to feed the exhaust cam through because there doesn't seem to be enough slack in the...

    Engine reassembly question "1,4T"

    never mind i figured it out. chain was in the way preventing the motor from spinning completely.

    Engine reassembly question "1,4T"

    Ok thats what i thought. Now here is the 2nd issue. The manual says to have cylinders 2 and 3 at tdc to reinstall the cylinder head (1st one to fit rings in cylinders). The engine was already in that position which was great. But my 2nd problem is now the engine doesn't appear to rotate...

    Engine reassembly question "1,4T"

    So I'm currently in the process of putting my engine back together after completely resealing it and I've hit a wall. I'm just about ready to put my cams back in but while reading the manual I cam across it telling me this . What exactly is the "1,4T" mark/position? Does this mean that cylinders...

    1981 cb750k Carb fuel line routing

    Would the floats just be sticking in a certain position? I rebuilt the carbs and the needles weren't replaced so that could be a possible reason.

    1981 cb750k Carb fuel line routing

    Alright so bit of a new issue. Since last posting here I've gotten the bike running great via bench tuning, playing with the idle screws, and getting new boots. My current problem or concern is with the fact that carbs are just pouring fuel out like crazy when i have the bike running. Right now...

    1981 cb750k Carb fuel line routing

    Scratch the exhaust concern, found out the exhaust flanges were not facing the correct direction so when i flipped them the bike was way quieter and sound WAAAAy better but the concern with the idle is still there. With the choke on it goes to right around 3000 RPM then when i disengage the...

    1981 cb750k Carb fuel line routing

    #1 Good to know, Lets see what happens when I get the choke thing figured out #2 the instructions were pretty poor to be honest and included no pictures. It didn't mention anything about the flanges. #3 No i didn't... going to try and do that now. Whats the best thing to use to plug them? or...

    1981 cb750k Carb fuel line routing

    Alright so finally managed to find some time to work on the bike and try and get her running properly but I'm definitely going to need some help from some more experienced people! The bike has been sitting for a couple of days now without being turned on. So today I hooked up the tank to...

    1981 cb750k Carb fuel line routing

    Alright well then i removed the vacuum operated fuel shutoff valve lmao. Is it alright to run the fuel line from the gas tank directly to the carbs (specifically to the large fitting between carbs 1 and 2)?

    1981 cb750k Carb fuel line routing

    So I asked a friend about the valve (he owns a cx500 so is a little familiar with bikes). He told me to just remove the valve (he referred to it as an accelerator pump) and run the fuel line from the tank directly to the fuel inlet between carbs 1 and 2. So I did so and the bike started right...

    1981 cb750k Carb fuel line routing

    Is the vacuum valve the piece that sits on the carbs that has the multiple hoses fitted into it?

    1981 cb750k Carb fuel line routing

    So after letting the bike sit over night I tried to start her this morning and nothing. Looks like were back to square one and I don't really know what to check at this point. I just find it interesting that when I put the gas into the bowl she fired right up with no problems and now even though...

    1981 cb750k Carb fuel line routing

    well she started right up! but I think I may have run into a new problem. So after I got the bike started I turned it on and off a couple times after letting it run for a bit. Turned it off to hook up my carb sync, turned the bike back on, fired right up, idled fine, then the idle dropped and...

    lmao sounds good! thanks so much for the advice! I'll check back in and update once I try filling the bowls with gas.

    1981 cb750k Carb fuel line routing

    Is there an ideal amount of gas I should be putting in each bowl? also a couple of friends mentioned to put a little bit of gas in the cylinders to help in the first start up. Should I do that as well? Thanks for the reply!
