Thanks for all the help, guess this is just a simple case of 100+hp and three years of abuse on the track. Could have been worse had I continued to oil my rear wheel, thanks STT for getting me flagged off the track before things went further south!
Chris at CCW is hooking me up with a spare crank case

so now it's just a matter of getting out in the garage to the 100+ degree heat and getting to work..........
