Half of this board is about jetting.....have you read through all of these threads on it?
I myself have done the cam-mod, and I bought the www.jdjetting.com jet kit, and it works excellent. Before anyone here can help you, you need to atleast post your elevation, and what mods you have done to the bike motor wise.
OK seriously.....did you read the multiple other threads on how to get your YFZ? If you don't give elevation.....we could have you jet your bike for 12,000 feet...when you could be at sea level. then your jetting would suck, and we'd look stupid (in your eyes).....so you have to give us info, before we give you answers. I told you what jetting kit I bought, and used. It came with instructions, and I recommend to anyone needing a jet kit to use it.
So those are very helpful links......if you don't understand what some of the numbers mean, or have a hard time figuring out a specific problem, then post that......the "please jet my bike" threads are wearing very thin. I will be glad to help you out if you give all the info you can to a specific problem.
