I really need help i have all my stuff for my raptor like the uni air vents and the air filter and the slip on, but i need the jetting! i dont know what to try.. Are there and kits that tell you excactly what you need or a website (hopefully) that tells you like with x amount of air flow increase and x amount of exhaust increase at this elevation at around 75 degrees what jetting you need??? MAYBE someone with similar mods with me can help me, i live like 90 feet above sea level i really need help guys! thanks so much

 

go to you local dealer have them order you CT needles, best on the market, theyll know what size according to engine mods. CT GET THEM, dont skimp on other needles use these. and for the love of god do not waste your money on that edlebrock carb. get a high performance cam if your gonna spend that much money. a good friend of mine told me you can use 38-39mm carbs off a banshee on your raptor takes a little tuning but performance for the money is right on.

 

Not to flame but theres a little part of every rappy that wants to be a shee [img]i/expressions/face-icon-small-smile.gif[/img]

Certainly not the '80s styling, oil burning, top-end rebuilding, rotten-handling part. Mebbe the acceleration part[img]i/expressions/face-icon-small-wink.gif[/img]

 

Im looking at your set up..i think you need to go 160-165 on the jets..But its kinda hard to say..I was running 170-175 on the 686..and it was dead one...

 

I really want to do it myself, but im just so confused on what i have to do to take it off im one of those mechanical learners i have to see it to learn it and i get so confused when people try to explain it to me, especially online. So i will buy the 16-165 and hopefully it will work out, if not it should be like right around their, I will only have to buy main jets right? keep needle stock?

 

dude look up dual fuel feed on the 660 . did mine a month ago nothing and i mean nothing could catch me no even a 2stroke . it only cost 150.00 and it was a very easy job. damm i love my craptor
