Hello all, In the last couple of years I bought a 1961 500 Twin Sports. It was in boxes part from the engine which was in the frame. The engine had been restored which I verified with the firm that did it. To cut a long story short, I restored other parts and began to reassemble the bike. Gear box on, clutch fitted, primary case fitted and timing side assembled and fitted. I then went to turn the engine over. It was stiff to the point of impossible to turn over. I took the heads off, the cylinders and pistons. I poured some oil on the crankshaft bearing, and can now be turned over. the right hand piston was stuck in the cylinder, I lubricated that and it now slides up and down as does the left.
My question is, how should the crankshaft feel as it is turned over with the top of the engine off. Should there be resistance
I have a 2003 Indian bullet, and when I depress the decompressor, I can very easily turn the engine over. Much more easily than the twin.
The bike left Reading in 1961 and was exported to the USA. Some how it found it's way to Tasmania, Australia, where it lives now.
I'm hoping for some bright ideas, without dismantling the bottom of the engine.
