can't remember exactly;I think about 60 or 70 $. I'm really not sure if you will still need the kit for those carbs, mine are still stock, but I'm sure some one else could answer that.
I got mine from toomey. not sure how they compare to others, but I like mine. comes with caps, cables, idle screws, and even the drill bit and tap you need for the idle scews and easy to follow instructions.
I woldn't do it! my brother has a 400 ex w/440 kit, full port,fmf pipes rev box I think stage 1 cam and high compression pistion and I can even beat him on my stock yfz. Really torquey though, good if all you do is ride wood trails and wheelies. there is a reason they want to trade for your banshee
planning on getting my cylinders ported and I have my case split right now and figured it would be a good time to do it. My ? is exactly what part of the crank do you weld(any pics would help)? I can weld it my self if I just need to know where.thanks in advance for any help.
BTW, I have t-6s and head milled .020" with stock cylinders. I also have a set of t-5s that are going on my other bike that I will have ported. sorry, this is my first post and I have not figured out how to post my sig.
