I have just put on slp pipes and power dome heads with their clutching and jetting specs. While I had things somewhat tore apart, I was greasing, lubing, whatever else I could think of while it was apart and had easy access. One question I had was about the water pump, I read on here it was oil lubed. What kind of oil and do I fill it through the bolt on top of the pump? Any other suggestions or info on this setup would be appreciated.
