Alright, let me explain the situation. I just got 2003 gp1300r from a old man. The ski hasnt been used sence 2005. He told me it was running when he parked it, it just didnt have any power. So i brought it home and cleaned it up. Ive ran a compression test, which were 1-105psi 2-115psi and 3-120 psi, i am a little worried about the differce between 1 and 3 but i think there is a alawable 15% differnce, not sure though. I do have spark, so i dont think there should be issues there. so here is my questions. I have two polaris skis and pretty fimiliar with them, but the yamaha is a differnt beast. What should i do from this point. I tried to drain the fuel/water seperater, but no luck, im affraid im going to break it. Is there any fuel filters i should change or clean. What is some of the issues that would cause a power lost. Im thinking maybe the cat, and would it be wise of me to get the cat removal set up.i havent tried to start it yet, i dont want to rush this. so any help on were i should go from this point would be great, and im hopping yall can walk me through this.
