running lean

hey guys what might be the source of my plugs running lean? i assume they're running lean cause they're super white.... and they're gapped to .05 like they're supposed to be....
thanks a bunch

Alldata tells me that the specs for the plugs are 0.71-0.78 mm, or for those of us in the US
0.028-0.031 in.

hmmm thats weird, my manual says .05..... maybe i'll try regapping them and see if it helps
thanks :smile:
