I would really like to rebuild the engine but not tear the bike down just yet. Any one got any good sources on motors to rebuild?

It is easier to say what I haven't replaced then what I have.

Possible worn out valve oil seals or maybe valve guides.
Suggest leak down test to determine extent of compression escaping past pistons and rings into crankcase.
Possible head gasket leak.
Possible clogged crankcase breather.
Correct oil viscosity?
Any obvious leakage from engine seals?
Just thoughts.
Good Luck!

Possible overheating for whatever reason, such as brakes dragging, worn chain, low tire pressure, bad bearings, incorrect ignition timing, improperly functioning advancer, too lean fuel mixture, too low fuel level, incorrect spark plug heat range, etc.
Good Luck!

I have not done a leak down test yet.
-I upgraded the coils and ignition to a Dyna system
-re shimmed the valves and resealed the head casket
-No leak from the engine.
- new K&N airbox filter
-Weirdgeorge wire upgrade
- new battery
- new oil
- rebuilt calipers and new pads
- wheel bearings seemed fine on the when it was apart
crankcase breather what is this?
How can you tell its overheating?
I know I have some exhaust leaks at the header and carb (parts on the way)

On the road it runs really well. I have only ridden mine so I don't know what it should be like

If no oil leaks from engine, crankcase breather is likely clear and okay. The breather is usually connected via a short S-shaper rubber hose connecting its outlet to bottom of airbox (where crankcase oil vapor is drawn back through the carbs into the engine where it is recombusted and expelled through the exhaust. But sometimes owners choose to bypass the airbox and just route a longer hose from the breather to expel underneath the bike.
Engine running too hot for whatever reason could cause oil burning, usually noticeable from exhaust.
Any white smoke noticed coming from exhaust, especially during acceleration or deceleration?
The leakdown test is more definitive.
Good Luck!

38km+ is what the speedo says
About 24,600 miles, and pretty low to have already worn compression down to 100 psi, but level figures are favorable.
Unable to accurately diagnose absent info about smoke from exhaust, and leakdown test results would also be most helpful.
Good Luck!

The thing is that I hardly noticed any oil leaking from this spot. It must have all come out while riding and only a tiny drop would show occasionally on the garage floor.
Thought I'd mention it as something to check. There are a few seals behind the left side cover to check. I cleaned up the whole area to help find the leak.
