Actual Garage find

I just got my mits on a really nice 1981 CB750 Custom that has been put up for a very long time! - 28 years!
Bike has 9000 miles on it, motor turns over and it is all there.  Previous owner got bug to mess with it @ 2 years ago, bought carb kits, removed em then did nothing.  This is my first Honda and first bike in 20 years.  Give me some advice he folks!  Tires are cracked but do hold air - What brand do I replace with?? Dunlop?  I am a Bona-Fide Gear head and do most all of my own work but need your input!!!!  Will post pics soon!

 Well put them up Boxeratheart picture's l.o.l.
    I take it you have A strong beleaf this bike will run(as I did mine).your carbs were apart so thats a project in it'self,Get a manual to have near bike at all times,the F.S.M. on here is best.
   I'd did a whole lot of cleaning,carbs, tank, oil,chain,points/plugs(new).If you can afford to get new Where parts are vital do it don't wait till later after you sucked in dirt and rats nest(no telling).
  After you fill all is clean N fresh that going to go thru/into the engine Fire it up and time it.
    Be honest with you thats as far as I went on my own,These guys no the stuff,but each there own .

I only run on Pirelli MT66 Route tires, front and rear.  Best tire I've found yet, have had them on three different bikes, loved them on all.  Superb wet traction, nearly immune to grated bridges, and tar snakes.  Whatever tire you are interested in, do a search for reviews, online, before you buy.

Since it is an '81 Custom, I assume they're tubeless.  If you want to simplify your balancing, buy some air soft BB's (the heavier kind), and weigh out enough to cover the amount of weight needed in normal tire weights, then add them to the tire, on the rim, seat the bead, and done:  they will dynamically balance every time you hit 20+ MPH, auto-magically.  Only catch is, you can never use an aerosol flat plugger, as they will cause the BB's to glop in one spot, throwing the balance way off.  You will have to use a tire plug system, should you suffer a flat.

Let us know what else we can help with.  Cheers!

I used shinko for tires. Been good to me and cheap to boot from motorcycle superstore.
Anyways, do the full tune up listed in the manual and get the carbs put together and set to base settings.
See if that sucker fires.
Good chance you will have some leaks from seals and such so use an inexpensive 10-40 oil. Once you go over everything, drain it out for a better oil.
Good chance you may have some smoking from the valves as you first run the bike. Put on a 100 miles or so to really work through the oil. Don't go too far from home though! Give it some good revs while riding, at least 6k or so. Shift through the gears a lot too.
For here, you should have an idea what, if anything you will need to fix.

Welcome!!!

I had a set of Dunlop Elite's on my bike a few months back. I put close to 5,000 miles on them and they showed very little wear. They would be a great tire for longevity or really easy cruising. I replaced those tires with Shinko 712 and absolutely love them! The radial gives a much smoother ride and the softer compound and improved tread design feels rock solid. Dunlop Elite's were the stock Harley Davidson tire for a long time. The gentleman I got my tires from told me that they work great on a heavy cruiser,but the harder compounds dont grip the road as well on these lighter bikes.

Your choice of tire really depends on what style of riding you plan to do.

Good luck with your new find and have fun!

It would be a good idea to check the valve clearance,check the rubber carb isolators for cracks,check the fuel tank for rust.You will need to flush the brake fluid and check the lines.
