So I had to replace the water pump and petty much all the lines for the coolant. I took off the whole top end of the Motor down too the oil cooler. After doing all the work I put it back together and it has a hard time starting I have bled the lines and it fires right up. When I shut it off it has a hard time starting like a very hard time starting . Can someone please send some advice so I can get my RR back on the road thanks to everyone that can shed some light.
