[Simmo737]

Bike year & model = 2011 ec300e with s3 head black insert
36 mm pwm carb ( as delivered stock)
Temperature (degF) =60 to 95
Elevation (feet) = 500 to 1500
Main jet = 172
Pilot jet = 40
Needle & notch = JD Blue 3rd from top
Air screw setting = 2..25 turns out
Slide = stock with perfect idle
Float= 8mm

Punchy racey, go up a gear or two and have awesome traction, hand over hand hill climb power with low revs and wide throttle openings, will not stall. Wheel stands in third from walking pace. Still revs out but not as moonshot as the suzuki needles. Has that "450 ish" roll on ( but I'm not kidding myself, it's not a fourfiddy)

This is my stock jetting. It's 1 step richer on the pilot and main than jd recommends, pilot for the grunt, main for the tighter squish head. Great plug colour with BR8ES and 80 to 85 km to reserve. Spooges to the end of the cap in half a tank.

Edit: For winter I've gone to clip 4, was getting a bit vibey and bit of a more obvious transition onto the pipe, with the clip movement fixed, I also use this all the time now, it's just so good.

Edit: this setting for me must be pretty well spot on, the air screw works.

Edit..again: after installing MPro T3 cable and getting some more freeplay in the cable, i went to P38 JD Blue 3 172 (jds recommended jetting except for one step higher on the main) , its just awesome a super linear torquey push from nothing to top end, with the usual surge onto the pipe...love it, as easy to ride as the nedw, but with punch! but its noticeably vibey -er, so I wrote to JD about it and got this back from JDean himself:

Mike,

Yes, you are on the right track using a slightly richer jetting (sic; for the higher comp head). The vibration is indicatiing you're making more power now. The jetting sounds close to perfect, and I'd suggest comparing the Red needle in clip position #4 from top to running Blue #3 clip position. The #38 pilot jet is a good setting. The main jet can be lowered a step or 2 with the 36mm carb, to near #168 or #170,-if you find the bike runs rich when you open it up after riding in slower conditions and find that the motor doesn't clean out quickly

1 also set float to about 7-7.5, AS 1.75 turns
