I have a 07..My retainer on top of the slide does not take the 4mm allen. It takes an 8mm socket. I have an hrc needle to put in, But, it just goes right through the retainer? Mt stock needle has like a small flange on it, that is what holds it into the retainer, then you put the little clip back on. Are the retainers diff on the 06/07. Because mine is not like the one in the pic.

Yes, the 2007's have a different needle assembly than the 06's. Good observation! Also I understand the older needles should work in the new carb...

hello and thanks for all the info i have this carb on a 440 and i think the person that had it before might have had a stock exhaust so every time i turn the bike off it back fires and off the bat its sluggish does any one know what to do .. i am thinking i need to change the jets what do you guys think and what jets to use i have a pro circuit t-4 exhaust thanks
