So as of today I am the new owner of a fairly clean 1974 CB750, 16,600 miles and only minor things to sort out before it's a nice runner. I know the carbs need to be synced and I plan on doing a full service on the motor as well as replacing the points with a Dyna-S ignition system. Are there any other things I should look out for? I'll post pics tomorrow!

First off, welcome and congrats!

If it's been sitting [or has in the past] the carbs may need a good cleaning. Why do you think they need to be synced? A full "3000 mile tuneup" may be in order as well, that way you'll know where you stand.
And how old are the tires? If past 5 yrs, I would start shopping.

Good Luck!

Or change your handle to oldoldskool!

NewOldSchool · « **Reply #4 on:** January 04, 2011, 09:20:05 PM »

Hahah I've had this handle for a very long time I always use it! Anywho, the guy I just bought it from claims the bike sat in a garage for 7 years before he bought it. It has a brand new front and nearly new rear tire and the forks and front brake have been completely rebuilt. He says the front wheel and steering stem bearings are new and the carbs were removed and cleaned out too. He also said he did not sync them after doing so. The bike starts fine but is extremely cold blooded and will not idle without holding the throttle at around 2000rpm until warm. After that it will idle ok, but roughly and will start first kick.

That sounds like a normal bike for it's age, you gotta goose the throttle a little on all my old bikes before they warm up.

So new tires as in the stubble is still on them and the manufacture date code confirms as such?

Before you go dyna-s, consider the HondaMan ignition. See the for sale section. It's cheaper than Dyna-S and uses less power (important), and and and.

Even if the tires look new, check their date (on the tire). The calendar age of a tire is important to note. If several years old, consider getting new ones.

We really need pictures

Don't fret if it burns oil for a while. If it hasn't run much recently, it may take some miles to get back in the groove.

NewOldSchool · « **Reply #7 on:** January 04, 2011, 09:41:58 PM »

Front is a brand new Michelin Piolot Activ and the rear is a 3 year old Dunlop 66V. Its missing the rear "bumper" that the signals mount to as well as the front signals. The exhaust appears to be a MAC 2 into 2 or similar and the front caliper has been stripped of paint. Aside from that it looks great.

NewOldSchool · « **Reply #8 on:** January 04, 2011, 09:47:47 PM »

SO for now I plan on replacing the oil, fresh plugs, gap the points, and sync the carbs to get it running and idling nicely. Also the clutch engages with only the last 1/4 inch of lever travel which will take some getting used to. Is this normal or is there a way I can adjust the engagement point?

faux fiddy · « **Reply #9 on:** January 04, 2011, 10:09:04 PM »

Some say to adjust the valves and timing chain before the carbs sync.

Beautiful bike!

Don R · « **Reply #10 on:** January 04, 2011, 10:50:57 PM »

lookin good! If you want signals (winkers) they are around and the wires usually just plug back in to the harness.

Johnie · « **Reply #11 on:** January 05, 2011, 04:52:00 AM »

So what is it that previous owners don't like about front and back blinkers? Nice looking bike there.

Nortstudio · « **Reply #12 on:** January 05, 2011, 05:39:16 AM »

Beautiful bike!

+1 on the 3000 mile tune-up (cam-chain, valve clearance, timing, full clean & sync of the carbs) . Let's you know where you stand, and if/when you have an issue (especially when you seek help here - it will be the first thing the 'old schoolers' will ask), you will be that much more informed about how healthy the bike is.

thats awesome! i love seeing these nice clean bikes, cant wait to get mine put back together.

ekpent · « **Reply #14 on:** January 05, 2011, 06:47:03 AM »

WELCOME. Good looking machine. One thing I noticed so far is that your fork ears look to be replaced from a 72,notice that you do not have the holes in side to mount the front blinkers.You will have to shop for K0-2 for the blinker - stem combo that mounts where the headlight bucket bolt is. Front fender is probably a supersport model.The red was used on the 75-76.Petcock on the left would be a 75-76 tank. Always a good idea to check your serial numbers on the engine and frame on these old girls to see their actual mfg date,lotta swapping on them. Enjoy your ride its a nice one. Eric.

NewOldSchool · « **Reply #15 on:** January 05, 2011, 07:18:41 AM »

Thanks for all the info! I plan on doing the full service within the next few days and slowly bring the bike back to factory stock condition as time and my wallet allow. For now its a nice classic bike to maintain and ride!

ekpent · « **Reply #16 on:** January 05, 2011, 07:24:00 AM »

Are you down in Florida? Looks nice and warm and green. Sigh as I look out my window here in Mi

kck3 · « **Reply #17 on:** January 05, 2011, 12:49:57 PM »

The paint looks amazing for the age of the bike. Nice score.

Stev-o · « **Reply #18 on:** January 05, 2011, 04:47:57 PM »

Looks very nice. Mind if we ask how much you paid?

Only negative I see is a poor copy of a seat cover that he put on, but that may not bother you [I woulld have to have "Honda" on a stocker bike].

Congrats!

Popwood · « **Reply #19 on:** January 05, 2011, 05:54:18 PM »

Very nice lookin' ride, and welcome to the forum. Always start with a basic tune-up to establish a base line of where you're at. And besides, as mentioned earlier, that always precedes a carb sync.

madmtnmotors · « **Reply #20 on:** January 05, 2011, 07:31:34 PM »

One other item that you may consider is connecting overflow tubes to the bottom of the carbs. If the fuel level rises above the correct height (worn or stuck float valves, leaky seam on a brass float, etc.) and the carbs overflow, the excess fuel is dispensed out those little nipples on the bottom of the bowls. Those overflow tubes (stock) are routed behind the engine, down through a metal bracket with a wide oval opening on the back of the engine so this excess fuel falls to the ground behind the center stand, intead of dumping it onto a hot engine. Unless you intend to try your hand at impersonating Nicholas Cage in "Ghost Rider".

Very nice looking ride, seems well kept. I'm surprised a PO felt compelled to remove those overflow tubes.

NewOldSchool · « **Reply #21 on:** January 06, 2011, 01:17:08 AM »

No problem I paid 3100. So far I've adjusted the valves, timed it and adjusted the came chain. I had to order an oil and air filter online becuase no one had them in stock so that's next. A local shop quoted 35 bucks to sync the carbs.

dave500 · « **Reply #22 on:** January 06, 2011, 02:37:32 AM »

thirty five bucks?to sync the carbs?,so it only takes fifteen minutes?

lrutt · « **Reply #23 on:** January 06, 2011, 04:10:02 AM »

I don't understand why you'd jump to replacing the points. There is nothing wrong with the points setup. They work just fine and have been for many years on these bikes. And points will ALWAYS get you home. Can't say that for electronics.

Otherwise, nice looking bike. Extremely clean but strange they dumped the rear grab bar.

I wouldn't have paid £2,000 for it seeing that it hasn't got a proper cam chain.

Perhaps it's one of theme Acme came chains.

To be perfectly honest, I wouldn't risk riding it if I were you....send it to me and I'll have it put down for you.

Enjoy your ride mate and be safe.

Sam.
