Finding the right jets

After doing research on here and a couple phone calls I have determined what jets to start out with. I have a 05 yz250f that has a FMF power core 4 muffler on it and soon to have a mega bomb. The jets I want to start out with are 180 main, 42 pilot, and OBDLR needle. Now that I know this is a start finding a kit with all this in it is proving to be a little more difficult than I had thought. Any help would be appreciated. 

Looks at the FAQ, get the Yamaha part numbers, and order them individually.

Thanks I have found the main jet individually just need to find the OBDLR needle.
