Well crap, I pulled the plugs and found 2, 3, and 4 covered in oil. The plug on 4 was just wet with oil and looked like it had been barely firing. The strange thing is that #1 looks really rich but no oil that I could see.
Anyone have any idea what could be going on here? I'm going to tear it down again this weekend and see what I can find, but I'm not really sure what would cause this. It absolutely does not leak on the outside at all though, and to the best of my knowledge it did not blow oil before I took it apart.
You said you took it apart and replaced all the gaskets.
Did you measure and hone the cylinders and put new piston rings in?
If you did not it will keep smoking and burning oil forever.
The cylinders have to be honed id the engine is taken apart.
Did you look very carefully at the ring lands and measure them?
Did you measure the cylinders top and bottom and know the gap between the piston and cylinder?
About the frame.
Not every welder knows how to weld a motorcycle frame.
You have to hire someone that is a welder that knows about motorcycles.
Measure the front of the rear axle slot to the same place on the front of the frame. It should be the same.
Or measure from the front of the rear axle slot to the bottom cross bar that the center stand is attached to. Should be the same.
Some welders have only welded bar-b-que grills. Some welders have only welded steel buildings and know nothing about motorcycles. Be careful when hiring a welder and ask them if they have experience with motorcycle frames.
BTW...I am a certified welding inspector. And I have spent much of my life welding motorcycle frames.
