Hi, I previously owned a Yamaha Waveblaster II with close to a stage 3 kit on it, but i bought it that way. I just bought a 2000 Yamaha Gp1200r Millenium Edition.. When i went to ride it my first time it would go from 0-14 very slowly even when i was full throttle.. then after 14mph it would take off like a bullet. I went to a mechanic and asked he said i need to have my carb rebuilt/cleaned, and my fuel system flushed/cleaned. I was thinking if im going to have a my carb rebuilt why dont i get some upgrades... so if you know of any please post a list of Racing Carburetors that would fit my Jet ski... i am all about speed!!! as well what else i can do to it to make it faster.... i was looking at a Stage II kit, if anybody has any info please tell me about it, and what else i can do to my jet ski. I am not looking to buy everything right now. I would like it to be a fun project between my dad and i to spread it out and not buy all the parts at one time... but i would like a few currently. I also heard from the same mechanic not recommending buying a new Exhaust for the PWC because they are not reliable.. please help ESPECIALLY ON CARB... thanks alot!
