You are very welcome and maybe I'll get a chance to actually ride the TM this week. Let me know if you get the pics; h/j off.

2010 bikes were fitted with Keihin Air Striker (I) carbs, identifiable by the dark grey screw on cap.
Most if not all 2011s come with the Keihin Air Striker II which has two screws retaining an irregularly shaped cap (necessitated by the slide return spring and arm) . If you can weed through the posts here (many don't identify the carb model so its a little bit of an egg hunt) it seems like the AS II is richer in general than the AS I (more efficient fuel pick up perhaps) and so needs slightly leaner jetting.

I don't agree that they have gone to a 36mm carb for 2011. As the previous post stated, they have used a 38mm Air Striker II. It does like to be jetted leaner than the previous models.

probably should of added that here in new zealand the only 2011's we got were the 300 e-starts, Ive pulled out my carb and 1 other out and they are 36mm even tho the spec's do say 38?

I haven't measured mine. It definately is the ASII model though and does like to be jetted quite lean compared to previous models. Doesnt explain why it still pulls so hard up top with a 175main when the KTMS are running 160/162 mains with their 36mm carb.

I was sure here in new zealand we got the same model 300 e-start as you guys in the usa so would be interesting if one of you could have a measure up of your carb? and wonder if the euro model that they and australia get is the same?

Thats what I've got bru! Euro model in Aus.. Its definately the AS II with the flat metal screw down cap. Also likes to be jetted much leaner than anything I could find in the jetting thread. I just thought it was a freak at the time but a 36mm would make sense somewhat.
Can I ask you what your jetting specs are, just for comparison? |

I'm running a 180 main 38 pilot and a red jd needle. I've also just noticed on the carb cap next to the were the cable goes there hex shaped hole that has 36 stamped in the bottom of it.

I'll check that out for sure when my new needles arrive.
One question though, if we're running 36mm carbs like the ktms, granted engines are slightly different, why do they all run 160,162,165 mains, and we're running 175+? Edit: also had a look at mine. Clearly stamped 38 in the top plate. Most strange! Last edited by Jakobi; 03-03-2011 at 08:00 PM. Reason: Checked Carb |
