It really doesn't matter if you flush it or not.

If things inside are throwing metals parts around, filters, new oil, a diesel fuel flush......none of that will help.  Engines cannot heal, and you really need to take something(s) apart and see what is damaged/broken/worn.

You stated the valves were adjusted at the TDC just after the exhaust valve closes.  That makes me think you adjusted at the wrong TDC, as you should have rotated the crankshaft another full revolution after the exhaust valve closes.  (When the exhaust valve is just closing - the intake valve is just beginning to open for the intake stroke, and both valves are supposed to be slightly off the valve seats (valve overlap).  If you adjusted the valves at this point of rotation....the valve clearance is going to be too big when you check them at the proper TDC.

You stated the clutch drags, and that the engine slows down when you pull in the clutch.  This is an obvious sign that you did something wrong inside, as the engine should have less drag with the clutch pulled in.

If you did not take the head cap off, and you rolled the engine around while working on it and putting it back in the frame - you most certainly had a dry "well" under the camshaft when you started the motor up.  It could have damaged the cam/rockers in a very short amount of time....especially if you had opened up the filter housing and the oil pump had to fill that cavity up before it would pump any oil to the head.  If this is what is damaged, it can all be fixed with a new/reground cam and new rockers.  You should start the engine up and let it run for about half a minute - then take the front valve inspection cap off and see if everything is coated with oil.......this will confirm if you oil pump is working or not.

Once again you are not listening to good, sound advice.

Don't dump oil down the head, you won't learn anything from it.

Start the bike, run it 30 seconds, remove the valve cover and look inside...hopefully you will see a coating of oil on the parts, and that will confirm the pump is working.

I agree , good idea !

Dave,

"When an engine is rebuilt of the head cap is removed - it is best to put cam assembly lube on the camshaft and rockers to lubricate them until the oil begins to flow."

Cam Assembly Lube is something that I am not familiar with, although the term is probably self explanatory, what would I actually ask for when I go shopping.

Dave,

Thank you.

I have used Assembly Lube and I never bought a cam that came with lube.

Uhm, your bike is plenty "broke in".  Just ride it till it runs like a turd.  Then rebuild it.

And right there,as I quickly scanned the thread, I wondered if this one had degenerated into discussion of online colonoscopy.  

It ran great for awhile, then I fixed it anyway .
Put Whatever you touched BACK where it was.
Now, here's the deal on fidgeting with adjustments.

Any time you decide to turn an adjustment, you First Determine exactly where it IS adjusted by GENTLY closing it, carefully counting the turns. Marking the adjuster And the carburetor with a Sharpie is a sharp idea. Then you back it out to where you were and add a quarter turn or so. That way you can get back to,


It ran great for awhile..


Now, since you have so Clearly demonstrated that you screw yourself almost every time you decide to do something, why don't you Try mentioning what you're thinking about doing and see if MAYBE the people here can possibly head you off and keep you from screwing up?

Did dad bust you upside the head with a three foot 2X4 for
Fixing the problem that didn't exist?

It's probably a good thing, really. Keeps you from getting killed in traffic.

I'm curious,,, how often do you grab a hammer and smash a thumb? You learned that hurts, didn't you?
Why do you continue to pick up tools and mess with machines?
If it ain't Broke, DON'T FIX IT!
And if it Is absolutely necessary to work on something, ask BEFORE you choose a course of action.

You have untold man YEARS of experience at your disposal, yet,
You choose to continue to Do things without asking. You don't
Know the little things you don't know.
The people here have been pretty patient, offered their best advice, and it takes Time to read the problem, argue back and forth for details, get an accurate picture of what is going on, then think about it, then type an answer. You're a frustrating student. You're well old enough to do better.
Self discipline is in order. One day dad won't be there to keep you fed and clothed and housed. When that reality sets in, you Better be able to make it on your own.
I think you need a grown man job with manual labor and goals and a deadline. If you can swing a hammer and run a tape measure and a saw, a dude your size could make out framing houses. You might start out picking up scrap, hauling lumber to the crew, whatever,, just Get the Foreman to give you a chance, then Do what you are told and Don't try to
Improve the system,
Change the way they do things,at all. They have been doing it longer than you, I promise. And, as you've seen, sometimes your great ideas really aren't that great.


AAAH! I see you decided to Not admit that.. well, too late, I read it. I wish I had hit the quote button.
