G'day fellas, has anyone got a scan of a Norris cams catalogue,I am chasing up various timing and tappet clearance specs for as many Norris Triumph 650/750 cams as possible.

I have the Vintage Bike Triumph cam spec scan that has an incomplete listing of Norris cams ,its helpful but there is info missing.

Even if someone can throw more light on 1555D-T650"D" grind cams (I recently purchaced an inlet and need more info especially on the Exhaust) ,that would be most appreciated.
Cheers R

Thanks fellas ,I am on the search for the exhaust cam that was partnered with the D grind inlet,just cant find any info at all.
Wes ,as mentioned I only have the inlet cam,if I lived in the states I'd be more than happy to drop by with the cam.
cheers R

Wes, this Cam will eventually find its way into a 650 preunit dragbike,I only paid $68 for it .Just got to find a suitable exhaust cam .
Tony, I get a different figure from both Pete and yourself
I calculate the cam lift to be 0.391" with stock rocker arm ratio
Valvelift divided by rocker arm ratio equals cam lift
0.435"/1.11 =0.391"
Cheers R
