New CB750K owner!

[poisonfox]

Hey folks! I just bought a 1981 CB750K off craigslist yesterday and so far am very pleased with the thing. Guess you really can't beat a Honda no matter how old it is!
Here it is.

Very nice!  As with any 'new' bike:  be sure to change all of the fluids; check the condition of the chain, and the tires; run a can of SeaFoam through the gas tank, following directions, but be sure to run it for 5-10 minutes, then shut it off, let it sit overnight (gives it a chance to dissolve varnish deposits in the gas tank -- visually inspect this for rust!), then run that tankful of gas out as soon as possible, to flush the system.

I, personally, would run SeaFoam through the crankcase, as per the can's directions:  add the correct amount, run the bike until the engine is warm, ride around the block, then drain it.  This will dissolve varnish and carbon deposits within the engine, turning the oil black, if this junk is present -- you won't need to do this again for another 30k-50k miles!  DISCLAIMER:  Some folks fear that this will damage the clutch plates, and they adamantly recommend against using any additives to the oil.  Based on personal experience with three different bikes, I would not hesitate -- I highly recommend it, but that is just me.  

If you need new tires, I would recommend checking out the Pirelli MT66 Route tires.  Look them up on Google for reviews.  I have them on all three of my bikes, and I will not run anything else:  superb wet traction, less likely to follow/be affected by road cracks, and grated bridges.  Can be run with/without tubes in them.

After that, check the bike over for routine maintenance issues, and repair as needed.  By the way, be sure to empty the blowby collection box:  there is a stoppered hose hanging down below the battery; pull the plug with a bucket underneath to catch any oil/water that comes out.  If nothing comes out, just put the plug back in, and go; if crud comes out, let it drain completely, then put the plug in, and go.

Be sure to download the FSM from the home page here!!!  With care, these are fantastic bikes.  You will enjoy it for years to come.  Cheers!

Nice looking bike. I really like the ammo can saddle bags. They are too cool.

Thanks for the tips! I flushed all the fluids and had to replace a worn stator, but it rode like a champ all season! Unfortunately, I removed the ammo cans. As cool as they looked, they rattled something firce above 3500 RPM!

I don't remember if I said thanks for your advice or not from over a year ago, but thanks! Bike's still running like a champ! Well, getting the carbs dialed in has been a challenge...

If the carbs are the worst of your problems, I'd say you're doing well. Keep the gas tank filled to cut down on rust forming inside the tank, run a little Sea-Foam every 4-5th tank (one ounce per gallon), change fuel filters regularly, and your carbs will thank you by atomizing their little aluminum hearts out for you.
