    New member hello and tank question

    You have to use english in the right way. You said 'I heard...' rather than 'Can you do this?'. If you heard then why would you be asking the exact same thing again??? '.... is separate from the petcock...' DID answer your question so the not helpful in any manner thing is wrong as the words...

    1980 cb750f super sport carbs swap

    Remove a fuel bowl and the rubber plug and look at slow (pilot) jet, if no screwdriver slot then '80 and earlier, if it has screwdriver slot then '81 and later, the jet unscrews. The early ones are pressed in.

    grease retaining washer

    Trying to remember what locates the grease washer, it may locate on a step in the stem OD. You actually could likely make one up out of thin metal plate or a big washer. You actually can simply install a grease zerk in the head and fill the entire head with grease but the excess amount will...

    Reg/rec, LifePO4 problems

    You are not showing all the wiring there, there are TWO battery leads going to the solenoid, it cannot work starter otherwise. One small one switches it on and off, the other is the huge big battery cable to starter that the smaller wire connects up when on and the big cable does not fuse at...

    grease retaining washer

    Partzilla.com shows the locking one to still be available here USA. Use '83 CB750SC (Nighthawk) as the bike type, the only 750 sold here in '83. David Silver spares should be able to get it.

    Reg/rec, LifePO4 problems

    Leaning toward battery, you only have 150 amp cap on a 110 amp current. Most batteries you pick double the starting current to easily cover it. Look at cars, 500 amp battery minimum to cover up to 200 amp starter. That 14ah was picked for a reason. You've gone too small, what so many do when...

    '79 750L Carb Re-build Kit

    PartsNMore are Chinese parts and likely the others too. Unless they specifically say they are not. I have used them but the needle tips are what bite, ethanol swells them and they also stick from drying up since ethanol dries up in bowls like 10X faster. Pretty hard to get needles and I never...

    The vacuum unit on a DOHC is separate from the petcock and often mounted on the other side. It has a vacuum hose going to the #2 carb from the left sitting on bike.

    '79 750L Carb Re-build Kit

    Randakk's if they still do them or Mike Nixon at the Motorcycle Project website but both are expensive. To get fine quality float needles instead of the Chinese crap stuff. If they put ethanol in your local fuel and you are having flooding issues they will likely continue, open carbs to air like...

    vague valve clearances

    What were the compression numbers? And having to set different idle mixtures for different cylinders is proof of needle seat damage from overtightening closed or idle fuel feed circuits are still partly clogged. Ideally they all use the same setting. Changing plug often appears to be the...

    Starter Solenoid Help

    The clutch diode prevents conflict between the neutral light and the clutch handle starter safety switch. Not being there power can go backwards from neutral into the clutch switch in a direct short. Battery runs down if not a fire outright. You need skills to do that workaround as well as to...

    vague valve clearances

    The ONLY thing that causes idle hang is vacuum leak, ort cracks in rubber manifolds, or sticking throttle or sync with the carbs ending too high at butterfly slightly open. Lean and rich will NOT do it. Engine state comes into that, lack of compression makes you open the throttle too wide to...

    Starter Solenoid Help

    Neutral circuit (clutch diode) is green/red. Power to ignition switch red. Charging output from regulator to battery is red/white. starter circuit is red/yellow. You have to positively change something up, you can't just drop the diode-gone the neutral switch won't work. The leads tied...
