I don't want to go back and read it all, it's easier to just say Can't let it idle on the stand. Oil won't get to the high end of the cam.

Go down one size, but you may go down further. Carb tuning is a iterative process. Big jumps can hide important information.

I will check the cam chain and valves this weekend and the new smaller pilot jet comes in Tuesday!

I instlled the smaller pilot jet and got the fuel mixture screw at about alittle over 1 turn out it helped the sputtering quite a but but still not completetly gone. I have a feeling the valves need to be adjusted and hopefully that fixes it. That will be what I try next then if that doesnt work check the cam tensioner. The reason I am thinking the valves is cause it runs good until warmed up, am I thinking in the right direction?? right now I am running 1 size down on pilot and 1 size up on main for jetting from factory

Runs good until warmed up? Seems like too rich
Have you checked the carb float level? Easy to do with a piece of plastic tube on the drain thingy. High float level can do what you are experiencing
Checking valve clearances and tensioner would be good to do as the bike is new to you

Drain thingy??? I didnt write that Grin

Do I need to buy a caliper tool for measuring or what do you suggest A ruler can be used. If you are building a tool kit, I find a digital caliper essential.
