Hey, just a quick one really.. Decided to get down n dirty and service my bike today.. (1st time ever due to me only having it a year and its my 1st bike) After finishing it all i checked the oil, it was looking full, i had put 3.6 litres in it to get it up to maximum line, or thereabouts. I ran the engine to let the oil drain into the filter and re-topped up the oil, eventually i put 4 litres in. Now the spyglass is still only showing midway between high and low level, and in my manual it says it should take 4 litres to fill a dry engine which is about right.. When i run the engine, the spyglass drains and shows no oil in it, im guessing its because its flowing the oil around all the parts, but im sure originally i could still see the oil when it was running.. Just want to check whether this is right as i dont wanna ruin it.. It registers as having nothing in the spyglass at all. When the engine is stopped and stood still, its re-fills back up midway between full and low.. Cheers Ricky
