I am in need of richer needles for my mc21. If you have any HRC, JHA, or RS needles that will work in the mc 21 I am interested. NSR HRC needles a, b, and C.

I have the stock airbox withthe new Tyga carbon fiber open lid so I need richer needles.

If you have the part numbers, that would work in that I can cross reference them.

Not sure if RS needles are compatible, anyone know??

If they are do you know part numbers??

Thanks.
