Still have the 06 HRC leak jet in (I think its a #55) what is the part number or where can you get a different one, and what size seems to work best? any suggestions?

Honda part number for a #55 leak jet is 99108-MEB-0550, a #45 is 99108-KRN-0450, and a #40 is 99108-KRN-0400.

Yamaha part numbers for leak jets: 4JT-1494F-XX-00. Replace the XX in that number to get these various sizes (e.g. a 50 leak jet is 4JT-1494F-07-00):

#130 XX = 33
#120 XX = 31
#110 XX = 29
#100 XX = 27
#90 XX = 23
#80 XX = 19
#70 XX = 15
#65 XX = 13
#60 XX = 11
#55 XX = 09
#50 XX = 07
#40 XX = 03
#35 XX = 01

If you go to Yamaha of Troy or somewhere and plug in numbers you might find more in-between sizes. I didn't list some of them because a few have strange descriptions but I bet they are all leaks. Sometimes those descriptions are in error or inconsistant.

Another option is MotorcycleCarbs (http://www.motorcyclecarbs.com/index.cfm). They have an easy to use web page and just about every jet I've run across.
