Now I am VERY familiar with XR650R carbs and Edelbrock carbs but the FCR is new to me. My 450 didn't want to start unless I had the choke on, even when warm. The header also turned blue right away and was obviously running lean. I went ahead and ordered a JD jetting kit minutes ago but is there a particular jet I should replace in the carb so I can at least ride today? If I don't ride today I'll have to wait a few weeks. BTW, it would start right away with the choke on and using the hot start.
Should I lower the clip on the needle supplied in the AIS kit?
Richen the mixture screw?(currently at 2 turns out)
Any help is appreciated!

MY 06 450 was completely stock during break in -the pipe turned blue - so did a buddy's 450 that was broke in the same way. I did my mods after break in. No real reason other than wanting to see the result of each mod individually.
I think the blue colour is a result of the pipe reaching operating temp for the first time -regardless of mods or not. It will soon fade to a typical exhaust pipe colour.

Look at the jetting chart (sticky) and put those jets in (leak is important!)
In the meantime, just jet it richer on your pilot, clip on needle (down), and turn your fuel screw (out). Should get you through until you get the JD kit.
You may even plug up the holes in the airbox to get it richer, or get some dust in your filter
We have all been through this when you first get these bikes, alot of time getting the jetting dialed in, but once there you will be happy.

Ride It! you do not have a baseline from which to start you jetting. Too Much reading and not enough riding is the only problem you have now. It will start easier after break in ride and you will be getting more familiar with the bike. Have fun!
This may not be wise if the bike is too lean!
Try taping over the airbox side holes, and even part of the top opening if necessary, to richen it up until you get the jetting fixed.
Then go ride

Nah mate, hard to start = bad jetting.
sometimes hard to start is relative to learning how to start it. you will learn its quirks.
I can walk up to my bike, pull choke, touch the button, the engine will turn over 2 - 3 times and fire. How quirky is that?
