Dammit? Why do I do this?

Is it just me?

I've reassembled my motor with lots of notes and pictures and after reviewing the pictures realize while I was careful to make sure the two O rings, or packings as the parts book calls them, on top of the cylinders were 16 mm, I forgot to double check to be sure the ones that go on the upper engine case were right!!! This is for a 750K0 motor. When I measured the top ones I had put ones in about 15.7 mm and saw they didn't fill the space for them so changed them to 16mm. As you can see in the picture the lower ones look "loose". The oil for the head pass through these areas and I don't want to compromise the oil flow. Dammit. So the engine comes apart again.
Sorry, had to rant! Thanks for listening but don't tell anyone please.
"Do it again" Cliff.

Hire employees to do it for you, you will be amazed how many times it takes three or four attempts for them to remember how to do a job they claim to have been doing for 20 years.

Or it could be early onset dementia, yours or mine?... It doesn't matter.

Hi Mark! I'm sure it has something to do with my dementia. Good post on the screwdrivers! No one around here has heard of JIS so I'll look out for the Crescent one.
Cheers,
Cliff.

Yea, but whats even worse is when you get it all back together and you find you still have some parts left

and no idea where they go.

Magpie · « **Reply #4 on:** January 18, 2010, 10:12:07 AM »

Or find a little tiny o ring on the floor below the workbench - is it the old one?

Seems like everything I do on my bike I have to redo!

But that should make it twice as good as before, right?

Hi,
I am at the same stage of assembly on my sandcast. Thanks for the reminder. Looks like a good opportunity to install heavy duty studs.

In 1971 I replaced a bent frame on a CL350. It was my first attempt at bike building and everything was perfect! I have not had that good fortune since. Am now replacing a camchain link after running with a lowd tick-tick-tick because I did not check for clearance for the heavy-duty unit. Of course the motor has already been out of the repainted frame one extra time because the guys I hired to rebuild the motor with new pistons put the cam in at a quarter turn wrong. Nice back-pressure through the carbs!

Oh Yeah.......and last year it was the 12-over big piston kit replacement in a 305 scrambler. Everything was fine until the motor was fully assembled. Apparently the head gasket squeezed into the chamber because I could FEEL something when I cranked the motor by hand on my bench. So out it came and a smaller kit with barrels was found in my stash. Anybody got a super-sized head-gasket for a 305 twin?

Well, at least I don't feel so lonely now. Thanks guys!

Well, if we were all honest, I'm sure most of us have done it.
A motor re-do is at the extreme end of the sepctrum. bummer

It can be the little things like did I leave out one ball bearing from the steering stem.

I've redone my electrical panel 3 times because I keep thinking of a better way to do it.

Tail light 4 times.

Sometimes I gotta know when to leave it alone and walk away.

I feel you pain

If perfection is the goal, of course it will never really be 'done'!

Steve_K · « **Reply #11 on:** January 18, 2010, 03:35:30 PM »

When something does not work the way I expect and I have to redo it I say, "That was the prototype and I needed to check the design!" Sometimes people will believe it!

I'll be taking my front brakes aparts again this week for the third time. The brake light pressure switch keeps leaking brake fluid. Nothing like bleeding your brakes over and over. Such a fun process. Your not alone!

Sweep · « **Reply #13 on:** January 18, 2010, 04:04:27 PM »

I redid many things on this bike including motor, top end, bottom end, carbs, cabling. I'm not stone confident on everything except tranny as I'm about to re-embark on doing that one.

bubbafun101 · « **Reply #14 on:** January 18, 2010, 04:15:01 PM »

I have had that problem every time I work on my carbs. Not in 10 yrs have I had a "once and done" with my carbs. Sometimes you just wanna yell!!!

CB750Winger · « **Reply #15 on:** January 18, 2010, 04:53:41 PM »

Don't feel bad, I'm in the carb group. I can't believe I found the real problem after having them off so many times, everything is shiny just from handling them. At least I can have the four carbs off and on quicker than a NASCAR pit crew can change four tires.

69modelj · « **Reply #16 on:** January 18, 2010, 07:25:55 PM »

The worst feeling happens when you start the engine and discover the o ring you so painstakingly placed in it's proper location got bumped unknowingly during re-assembly. And it aint the damn bike's fault either

Kframe · « **Reply #17 on:** January 18, 2010, 09:17:06 PM »

Not really motorcycle related, but I hate it when I'm replacing the plug on the end of a power cord and I get all three wires perfectly snugged under the screws, and then I realize that the insulated housing or the clamp is still laying on the bench.

Doh!

yup, left one of the o-rings from under the cam tower out. i didnt realize it till i had destroyed a set of cam towers. thank goodness for the frame kit.

i always forget to put the seat down,.and my wife screams at me!

Syscrush · « **Reply #20 on:** January 19, 2010, 04:32:57 AM »

I always estimate work in 3 phases:

1) The time to do it wrong.
2) The time to figure out what was done wrong.
3) The time to fix it.

Hinz · « **Reply #21 on:** January 19, 2010, 05:32:04 AM »

bikes...cars....even posting replies on a message board. It seems like almost everything in my LIFE i have to redo at least once. No matter how much planning and research I do, inevitably it has to be torn down and redone.
At least it's not just me.

Don R · « **Reply #22 on:** January 19, 2010, 06:24:03 AM »

I had water running out of the bellhousing on my new pontiac engine, I pulled the trans to find the bad frost plug, it was the heater hose. There, I said it.

Ouch.

I'm a chronic do it again type. However, this is better than to do it wrong or poorly and then live with it/ignore it/hope it will be OK.

Many times I will come back on my steps just to check I bolted the door after I left home. I do it unconsciously, therefore I'm unable to remember whether I did it or not.

With bikes, I am very meticulous, but after things are closed, I start to wonder whether I put that tiny ball, or that washer, or whether the pistons were facing the right direction. To overcome this, I take tens of pictures along work. If doubt start lingering, I can always take the camera and check whether everything was as it should be.

Magpie · « **Reply #25 on:** January 19, 2010, 02:40:35 PM »

There is a silver lining to this. I found when I took the motor apart AGAIN that the head does not appear to be joining tightly to the cylinder block. There was oil on the head gasket and the head surface. The dowels may be too long or something else is wrong. I've changed the dowels and retorqued the head. A friend is dropping by to do a leak down test on Wednesday.

My first thought was carb work, but really I can't think of anything I've done to my bike that I haven't had to redo! This is my first bike, and I admit I don't know what the f&*k I'm doing, but with the help of the forum I always get through and feel good that I did it. I love having a bike that you can work on.

I wish I had a dollar for every time I've unracked and cleaned/blown out my carbs. I'd probably have enough to buy a cheap pizza and a beer.

Everything I do, I think I do twice or so, too. The carbs have stayed 'done' but will have to be repeated if they ever clog again... I have a creepy, touchy helicoil that had to be redone 3x (that's scary work, 'unscrewing' a broken helicoil out of already iffy aluminum)

Raul, I'm going to have to do like you do and take pictures. I'm the same way with my meticulousness until things are closed, then questioning myself.

Raul CB750K1 · « **Reply #28 on:** January 20, 2010, 06:26:04 AM »

My digital camera is as valuable as a tool as any other in my tool chest.

If you are worried for staining yours with greasy fingers, spend $20 on a used 3 Mp camera out of eBay. I have thousands of pictures of the innards of my bikes, cars etc. They come real handy at rebuild time, or just if you need to post some pictures to help somebody who is going through where you've been before.
