DUDE, go back to the thread you started about the exhaust recomendations for this bike, you could even go back to the threads I started when I was where you are now!...In short...even if you keep every thing stock you must set your float/fuel level!!!! Mine was set way way high,they almost couldn't be any higher,see,the dealer where you bought it won't see this as warranty issues they'll just tell you that what you want is to get performance work done,at least that's what I would think,I din't bother to take it because I don't think there would be anyone with the experience (that I now have) to diagnose and fine tune these carbs.I can almost garantee you dont need to pour any fuel additives or s**tcan the filter!!! Here's what I had to do,again,don't pay attention to my other perf.modifications...I lowered the fuel level to factory specs-around 7 mm,wen't up one size on the pilot jets-to 15's and went up to main jet sizes-157.5 for cyl.2 and 3,and 160 for cyl.1 and 4,set idle speed,set my mixture screws to best/smoothest idle AT PROPER TEMP.-around 200 deg. ,set idle speed again. This should get you ballpark,if not so close you'll be happy enough to leave it there. Now if your not comfortable with doin this your self then take this info to your mechanic and have him check these things,this eng. has almost 13 to 1 compression ratio if things are off a little bit rich or lean your gonna feel it!!! I know it's hard to beleive all this needs to be done to a brand new bike just to get it to run right but ... I've done it! Keep me/us posted!!!
