I wonder if anyone actually kept theirs at 3 turns out. I'm at about 850 ft elevation and did the Dynojet last weekend. It was 32F outside and I took it off the choke immediately after starting and it idled just fine, which tells me it's probably too rich. I'll play with the idle mixture screw this weekend, but I'm sure I'll end up turning it in some. I also worry about the screw vibrating out when it's screwed out that far.

 

Mine's running too rich. I put in the 38 pilot and the Kouba screw is only 1.1 turn out and it idles well right after a brief warm up with choke (which was drilled to 0.018). A little black soot in the tail pipe. Elevation is around 2,800 feet at home and I'll be going up from here most the time. Used the 2206 DJ kit with 128 main and clip in the middle, drilled slider (which is reversible - just put a little epoxy in the drill hole). Last tank of easy-riding yielded around 48 mpg, and was down to 30 mpg on some tough, slow trail riding last month (gears are also low at 13 front, 49 rear). TOO RICH. Thinking of returning to the stock #35 pilot (definitely) to give more room for adjustment on the Kouba screw, and maybe to the next smaller size main. Any thoughts out there for this rookie?

 

I have the powerbomb header w/Q4 exhaust and its a little louder but not alot. Definately sounds better too. Its not loud enough to wake your neighbors or too loud that it would bother you without ear protection. I also bought the 2152 kit from JCMotors. I currently have the 120 main installed till I replace the factory air filter and modify the snorkel. Just with aftermarket exhaust and stage 1 (120 main) jet kit it feels like i gained about 20% more power than I had with the factory exhaust and carb settings. Last week i finally went to a 13/45 sprocket combo and gained even more pull with that. With those few mods the bike has definately woke up from what it was when I bought it new.

 

I got a carb from another member with a jet kit I will let everyone know how the install went when I'm done
