Hello all. I bought a very nice GP 1200R with a Riva stage 3 on it ran fine last week this Saturday it started bogging a little. What id the proper setting for the high and lows please help. Motor was rebuilt 54hrs ago, it has Riva heads, free flow exhaust, solas impeller, jet works, intake grate, ride plate, tiny tack, fuel pressure gauge, ect.. Like I said ran fine last weekend, like a champ. Oh that's another thing what is the proper fuel pressure suppose to be does anyone have a diagram? it also has a needle spliced in the fuel line as well. Please help
