Topic: Beautiful 1972 cb750 with dagnabbit stuck engine

So you are uncomfortable posting shots of dirty motorcycle parts but have apparently no qualms, or shame, in showing us pictures of your vile, disgusting, mess of a kitchen that looks so filthy any salmonella, listeria & e.coli bugs in the area would most likely pack their bags and march off to find something less run down.

Bizarre.

Are you a fan of Nietzche?  "That which does not kill us makes us stronger."   I have lived my life making sure I kept my immune system in full power mode, I build up my immune system like a weight lifter.  Last time I was in jail in 2004 I still have the jail spoon, you get to keep your personal effects when you get out of county here.   I wash that spoon when it gets cruddy, I am not a squeamish type of man.  I re-use paper plates.  I am an immune-system building mofo.

Now as to the pictures I said WAY earlier in this thread -- "well the seat and tank are off for cleaning first, I got the tank done, next comes the seat.   I have no plans to clean the rest of the bike.   Not yet anyway.  I always put off cleaning until the end."


I set you picture-wanters expectation LONG time ago I aint gonna shoot this bike yet cause I AINT gonna clean it yet and will not shoot it until its cleaned, I am being patience on the un-sticking process you pls be patient on me getting it cleaned.  KITCHENS DIFFERENT KITCHEN ALWAY LOOK THAT WAY NOW.

HUy bud, can we see the bike?

I'm thinking somebody's immune system is blowing a fuse!!

MY KITCHEN DON'T LOOK LIKE THAT!

MY KITCHEN DON'T LOOK LIKE THAT!

Well I reckon I DID get too dependent on the ex there as she did all the cleaning.

I have not gotten the flu in 7 years.  I am never ill.  I think thats the kitchen talkin there now.


I made a great discovery -- there's a Harbor Freight just opened up near my place, I was driving 40 minutes one way to get to the nearest.  Now it's a 15 minute drive.

So I bought an extra-long 28" breaker bar tonight (I've been using a short 18" up to now) and tomorrow will go back to work on rocking the crankshaft.  I'm trying to stay patient and optimistic and I appreciate your support.

I wanna see more pics of the kitchen.

That's where I do all my bread and toast work -- the reason the stovetop looks that way is -- the toaster is just above there and I have put a cutting board below the toaster, on top of the stove there, and do all my bread/toast work there.  So it's hard to tell that I actually thoroughly clean the stove top on a semi-quasi-every now and then basis.   Plus I was in the Navy.  You do get tired, after years of being compelled by the UCMJ and various 'superior' officers to keep your personal sh_t clean as a gott-dang psychotic clean freak all the dang time.   When I got out no more cleaning like that I served the country with a psychotic squeamish clean freak giving me chit strokes then NJP/Capstain's Mast a couple times over nothing.

Thats a funny way of saying you are a dirty prick that never cleans anything........

Stop the teasing, I wanna see the bike!

I have pretty much decided that if I cant free her up over the next few weeks I'll put her in my storage and bust it out right before next spring for the tear-down.  I would truly love to get the thing freed up because it will be SO much easier to get the cylinder off the cases.  I don't treasure the idea of hammer+wood on the pistons, doesn't appeal to me, especially not with 4700 miles on the bike.  Pictures will come although why yall want to see a dirty surface-rusted '72 cb750 with tank and seat removed is a guess.   I'm headed over to the shop now to put my new 28" breaker bar to work on the crankshaft wish me luck dudes.

I will try to post a picture of my kitchen after I clean that one, with luck the toast dust on the stove will be cleaned, the motor will be spinning free and the bike will be cleaned by next week.

No longer following this "different" individual.  Guy has no bike. Found the picture on the net and is most likely a member on here who vanished a few weeks ago. Waste of space of this forum....

By they way, I was in the Army as well as my father. I was brought up to be neat and keep things tiddy. Even after my years serving, I keep my everything neat and orderly. I am in the process of teaching my kids the same. SOunds like an excuse as well as not posting a pic of the bike.

[Hush]

Lol yeah like Tews said, photos or it didn't happen!

[Stev-o]

No, he's got the bike. It's probably dirtier than the kitchen and doesn't want to show it.

Funny, the first thing I do when I buy a project bike is clean it! Just sayin...

You know what else is funny, i like to do that to the kitchen as well.....

My 28"  breaker bar is showing progress on movement of the piston works UNLESS there is enough give in between the big inside toothed wheel and the pistons.  When I rock the alternator bolt back and forth that big toothed gear moves a bit with the breaker bar motion -- but does not break free.

By the way I can get enough torque on this alternator nut with my breaker bar to
- compress the front suspension when I pull in the direction of normal engine rotation
- tilt the bike back when I turn the nut the other way

So I'm getting it to move.

However is it *possible* for the big toothed gear wheel that's inside of the rotor there, I'm speaking of the big toothed sprocket right up against the inside of the rotor and almost the same diameter of the engine case -- is it *possible* when I'm rocking the alternator bolt back-n-forth for that big sprocket to move and yet the crankshaft may not be moving (ie. is there a keyway on the crank with enough give so the sprocket has some tiny movement while the crank stays stuck)?  EDIT:  I fully realize the big sprocket freely rotate backwards, that's not what I'm seeing, I'm seeing about a 1/32" movement in BOTH rotational directions and I'm not jerking the breaker bar -- I'm apply slow, steady increasing force on the nut.

Now this big sprocket that's driven by the starter motor is only moving maybe 1/32" but it moves enough to be noticeable to the naked eye.  I'm worried that the crank is not moving with it.  Is that possible?  Sorry for the picture quality but I didn't get time to work on it until late in the afternoon and it started getting dark.

Wow - what is that growth on the rim??!

About 40 years of neglect I reckon, 1972 to 2011's worth.

[Hush]

With such little movement mate I'd say you are only taking movement from a few areas but not the pistons.
What ever you have poured into the spark plug holes, add some more and let it seep down for a few days, patience will pay dividends here.
I presume now that you ahve taken it Out" of gear so it is just the crank you are trying to turn and not the whole gear train?

[ABikeNamedTrouble]

Of all the possessions, things, skills, and bodyparts a group of bikers could compare against eachothers'...

kitchens?  really?

Yep it is in neutral when I'm working on the alternator bolt there.  I always do measure the remaining ATF in the bore holes and freshen it up as the final step in my procedure when I'm done with it for the day.  I fill the bores almost to the top.   I'm going to take a week off from rocking it and just let it set for a time now.   

I would like to get it freed up so disassembly is easier.  I am about 95% sure the prior owner lied to me about 'it was turning over last year.'  Good thing I only paid $200 for the dang thing.

[Hush]

I'll give you $200 for the dang thing!

Purdy good fake post ... has carried lots of folks along for 70replies so far  , except some of the details are lacking forethought; for example, a 28 in. breaker bar would INSTANTLY undo the rotor bolt when turned to the left on a stuck motor... but 'compressed the front suspension'... yeah right it's a beautiful K2 750, beautiful

I would truly love to get the thing freed up because it will be SO much easier to get the cylinder off the cases.  I don't treasure the idea of hammer+wood on the pistons, doesn't appeal to me, especially not with 4700 miles on the bike.

When a motor coasts to a stop, it usually stops with one cylinder at or near TDC on the compression stroke. With 2 cylinders at TDC, and the other pair at BDC, no matter how hard you hammer on the pistons at BDC they can't move; they as far down as they can possibly go. 1+ on trying to get it freed up by cranking on the rotor bolt. Good luck.

[ekpent]

If you have a good quality heat gun,not just a hair dryer,don't be afraid to heat those cylinders up big time.It will promote seepage of your fluids and expanding aluminum/steel can help.My little Kaw 350 triple was stuck and broke free when I heated up the cylinders to a nice toasty temp.  Worth a try.

PS-If you still have the $800.00 Sandcast as posted in that other thread lets see a pic of that please.
