I stripped and rebuilt the top end on my bike as I was getting water in the transmission and found there to be a small leak in the head gasket, the rings were just out of spec so they were replaced. i cleaned the head and replaced head and base gaskets then started to rebuild the engine. the problem i have is that i can now turn the engine over by hand without the decomp lever, the valve clearances are all in spec and the timing is set. would the compression increase when i fill it with oil? i really don't understand why its gone like this. Before i couldn't even turn the engine over by putting all my weight on the kick start lever.
