Pull your carbs and exhaust pipes and use a light to look inside ports. If the stems are wet with oil you know it's coming from the top end.

I have an 1983 650 nighthawk and bought bike in 2002 after previous owner had let it sit in his shed for the last 8 years. I rode it for a couple of years till my wife became pregnant, and put it away in my garage for a few more years. Brought it out 3 years ago and started to fix things up. In the mean time found this group and was able to glean lots of very informative stuff. With all this new found confidence, I decided to undertake replacing the valve seals as the bike was smoking a bit, and had been sitting idle for so many years. The whole procedure was a slow process, but I was able to replace them, reassembled everything and have it running again. But now it blows blue smoke even worse than before. It appears to be coming out both sides equally. Did clean up valves when I had them out, which was primarily wire brushing the carbon off. Used a bit of gasket cleaner on block and this may have cleaned the carbon off the top of cylinder wall allowing blowby. I have ridden it about 150 km to see if it clears itself up. So, I am not quite sure where I may have gone wrong. -- You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
