you'll find the needles that come with our bikes are lean from the factory (in addition to being different left and right). selecting your own needles would require a lot of guess work/R&D which the jet kit companies have already done for you in selecting their needles.
Ahh, I didn't know that about the needles. Makes sense now why they supply their own needle. I sent Dynojet an email and explained my setup and just asked them what they would recommend. The biggest main jet they provide is a 100. I have a feeling I'll need a bigger main jet.

I need to learn more about carbs... I'll check out the site you recommended.
