    350x main jet

    Anyone know what kind of main jet the stock '86 350x keihin carb uses? I bought some a few years ago and they were not right, so I took the old one into the local honda dealer and bought some correct style ones. If I remember right the first time I picked up jets from them they looked them up by application and gave me the wrong ones. When I went back I took the old jet in to match it up. I ended up keeping the first set I bought anyway because I left them at home when I went back. The problem I am having is I threw them in the same bag and now I cannot remember which one's fit. I need to pick up some different size jets and I am at work, my trike is at home so I can't go take it out to check. I think it used the longer hex style jet, but I also have some short flatblade style jets in the package. Is it the longer hex style or the shorter flatblade style?

    Not the exact ones I have but here is an example of the hex style jet I have (similar to this one anyway): http://cgi.ebay.com/ebaymotors/Keihi...Q5fAccessories

    Also, anyone know where I should start when jetting it for 4000 feet? It is 12:1 compression, .50 overbore, cobra exhaust, uni air filter, stock air box with lid, stock cam, strong valve springs. I have a 138 in it now which worked good for the stock setup. I also have a 145 and a 155. I was going to pick up a 150, 160, 165, and a 170. Thank you
