2004 450r with hrc-runs good but won't idle. adjusting idle speed won't fix it. Sunk intake valves? Also when it warms up the rpm's(not throttle or cable) seem to hang pretty high until I shut it off.

If this is a valve issue and I need to tear it down will a 11.5 piston work with the hrc cam? Will a white bros e-series slip on have gains over the hrc tip? Where can I get stock valves cheap? Thanks

Sounds like the valves to me. I would start by checking the clearances.
