bought a 06 660 from utah it has a 165 mikuni in it what do i need for glamis/phoenix? 686 high comp. ported/polished,k&n full intake,aftermarket muffler,stock carb not sure on cam,clutch and sheave if that matters thanks in advance ryan

Where at in utah? What was the elevation there?

5500 FEET DONT KNOW IF IT WASA JETTED RIGHT TO START WITH RAN PRETTY GOOD BUT DONT KNOW IF IT IS RIGHT`WOULD JUST LIKE A GOOD STARTING POINT THANKS RYAN

Bump it to a 175, might be a little fat but its a start. I would can the stock carb and put an FCR41 Keihin carb on it to really open up the port and polish job. Just my opinion...

how much is that carb and how much hp/tq would it add? thanks ryan also which bike is it off of?

Not sure how much, i know DASA racing sells a kit. I got mine from a buddy... But i think its ballpark 2-3hp? same for torque i believe. It has an accelerator pump, no more vacuum slide crap. Really helps with the low end.
