Just got off the phone with JD jetting and he said to try this mod to save on fuel.

Sorry but I have not seen an ASII yet. I would think that the float valve needle is actuated from a tab on the float like the original AS carb. Am I wrong here? Is it a fixed molded plastic tab? If not, and it can be bent, I'd start by setting it level like the old carb, and going 1mm lower until things get better.

Any pics?

The 2010 six days came with the ASII. That's what I have on my bike hence all the jetting issues I had bc everyone on here was trying to tell me how to jet it as if it were an ASI. Print a KTM manual off the internet and it will describe how to set the float. I have now jetted a 250 300 and 200 with KTM needles and jetting guide in the back of the KTM owners manual works great. I done this bc it seemed like I couldn't get other members on here to understand that there is a big difference between ASI and ASII

Hey Glenn, its completely plastic now and fixed except they added a very small plate where the needle hangs off the float assembly, I assume so it doesn't eat through the plastic over time.

Yes you need to jet the AS2 much leaner. Was your float assembly completely plastic on your 2010 AS2?

I cannot find what your suggesting. got a link?

My float assembly is plastic except the metal tab you can bend where the float valve is attached. You google 2008 KTM users manual and a pdf will be available for free. If you can't find it email me at onegreyghost@gmail.com and I will attach it and send it back to you

Thank you.
For others interested some info on Page 45 of this PDF link.

Same here had to reset the float and get the plastic out of the tank clean the carb and all has been good since

Bent the metal tab that the needle hangs from. You have to hold the carb at an angle so as the tab is contacting the spring in the needle, but not depressing it. My carb was set at 6.5mm from factory, I've lowered the float to 8mm, so therefore less fuel in the float. Only ridden the bike once as I'm waiting for snow to go away but I thought it was a thirsty machine. Checking Keihin's website they list a float height of 6.5 mm for a 38mm PWM carb. I assume that this is the factory spec for ASII. Didn't have any starvation issues on the one ride.

My YZ has an AS2 - this is from the Yamaha manual.
