Ok, so I did a bit of googling and found this:
http://www.factorypro.com/tech/needle_jet_wear.html That explains what to look for concerning wear in the needle jets pretty well. All the explanations of the symptoms match what I am seeing on my bike. So now I can't wait to tear into it again.
Do you know what I am looking at concerning the price of the needle jets? Should I also change the needles? Maybe it's worth considering a kit containing these parts - if that exists. Does it?
Any other parts I should consider changing when I'm in there? (besides the needle jet o-rings)
