    Guys, I've been trying to fine tune my '09 WR144 with the help of Walt, Darin and all the other great resources here (huge props) but one thing keeps confusing me...

    I've read a number of posts here that say the 6CHY17 RM needle is a half-clip richer than 6CHY16, I don't think this is correct, I think it's the opposite based on the following info:

    The info above is from the RM Tuning guide that dartyppyt shared with us (super helpful, btw!)

    I'm not crazy, right? All the info here points to the opposite of what is documented in that tuning guide, even the Needle Number chart has the 17 as leaner by half a clip.

    Hope this example helps:

    For example, a 6CHY17-64 needle in the 3rd position, with a 1/2 clip washer installed under the clip is the same setting as a 6CHY16-64 needle in the 3rd position.

    So the 6CHY17-60 thru 64 needles will be a 1/2 clip leaner than the 6CHY16- 60 thru 64 needles.

    yes, it does, thank you! the threads/posts i had bookmarked mention the opposite but now i'm clear (and not crazy) [IMG]

    (btw, i removed the last portion of my first post to not confuse the question)
