Clark or James, i've tried the dvp needle for the past few weeks in my 2000 WR I'm running WR timing, the needle at # 5, 48 pilot, 178 main. My motor pings under a load in the mid range at 1500'- 3000' elevation. I had no pinging prior to installing the DVP needle. I rode in the Inyo Mountains this past weekend and had no pinging above 5000' elevation. What's your take on this situation? Glenn .
