I know I need 2x 140 mains and 1x 40 pilot, but when I went to Sudco's page there were Mikuni Lrg. Hex, Sm. Hex, Lrg. Round & Sm. Round. WTH am I suppose to get? Also, the Factory Pro shop that I'm assuming makes the carb kits that Sherm's sold, in 45 miles from my house. Does anyone know anything about these guys? It would be nice to pick up the shims and jets locally. http://www.factorypro.com/products/Jets,%20Mikuni,%20buy.htm I posted the link, if someone can take a look and tell me which ones I need that would freekin ROCK!:pepper:

That narrowed it down a little for me thanks. The local place has the sizes I need but I looked at this chart http://www.keihin-us.com/list.htm and from what I gather I need 2 of the 28mm pilot jet I think.... please correct me if I'm wrong. On the bottom I can't figure out which jet type I need for the mains. I'm going to take a guess (bottom shows CVCVK road bike) and say I need the 8mm for the mains.... I'm probably way off.... :BLAM:

Jet size will depend on altitude above sea level, intake and exhaust system. Give me the info and I will tell you what you need. :smiley_th

oops, thanks! 87 ft. above sea level, about to put K&N pods on carbs and stock exhaust. I ordered the 40 pilots, 140 mains and shims to re-jet but haven't opened anything yet. Also what is degoating and is it in the Verses? (so you don't need to waste your time telling me something that's already been explained)

Yes it is, you remove the pipe that connects both exhaust pipes together I believe. Also try and do a search you might find more information about it.

Check the color of the plugs before you buy new jets, if the bike is running fine leave it alone. If it flees like it needs more on top end the replace the jets.

Lance, thanks for giving the sizes. As mentioned earlier, I already bought 40's and 140's and the manufacturer wont do an exchange and apply a %15 re-stock fee if returned. I know they're not much $$ but I'm penny pinching my way through this. If use the jets I have, am I going to experience any issues or will I just not have as much power or something like that?

You will be running "lean" like Vulcanjoe. Eventualy it will burn the exhaust valves.

You can try the ones you have and keep an eye on the plug color and jet as needed. :beerchug:
