    02GP1200R Jetting

    Im reading that there is a common Lean spot in the mid range of this ski.. and that the best way to protect yourself from mid range seizure is to rejet your carbs...

    so i have a USA model GP1200R with the ACC pump still on... Riva intake.... D-Plate... what should the jets/pilots/pop off and all those other setting be put at? i am going to send it to the shop for these things to be done.... so all i need is to know what to ask for... Im in Rhode Island, our riding air temp ranges from 70-95 F during the summer, its also a Pre mix ski and SBT recommends 32:1 mixture.....

    I was reading all the stuff on jetting these things, but seems that every machine is different cause of different things done to that specfic machine.... i dont know much about this stuff at all.. i wouldnt ever attempt to jet this according to what i know.. that would be very very bad... that motor wouldnt last 10 seconds... now if i do these mods it will make the ski more reliable..right? im looking for protection of my engine.......

    Many of the skis are common though (compression , open fa's etc..) The jetting above is proven to work.

    If you are not comfortable with your carbs you could send them to Carl @ Island Racing or Jim @ Jims performance. They will do the work 100%. If you update the jetting you are making it more reliable. You also get better throttle response
