What's the reason for running leaner than the standard hrc jetting on the main wppracing? Thanks for the input.

I would run anything from 180-190 youll be safe. Just dont go under 180.

Also, the bike has a stock needle. What position?

You have a ported head, If it was done correctly you should be able to run a smaller main jet.
Replace the stock needle or try the stock pilot and needle clip on the 5th slot.
I had the LRD system on my atv.
