I was approached by a young rider last week, who is trying to set his timing on his '84 Honda VF1000F Interceptor. He says he is setting the rear cylinders based on the 'TR' marks, and the front cylinders based on the 'TF' marks, both based @ TDC. The bike will fire and run for a short period, but that (his words) "the front cam gear gets sheared off the cam". I haven't seen the bike... I just happened to be hanging out at a local show 'n shine when he came up to me. Does anyone have a decent online technical resource that I can point him to? He says he's already tried the VFRDiscussion Forum... TIA.
