So it looks like the 'C' and 'F' may just be some date or batch reference rather than a change of spec. I had all 8 of the injectors tested and it looks like 1 of my originals was bad while 3 of the ebay purchased ones aren't looking too good either. The 4 underperforming injectors are going back on the machine to see if they can be recovered but its not looking too promising. I have a set of 4 now though that I can put on the H and hopefully get back on the road.
25/5/2015 - UPDATE: Injectors appear ok but she continues to sound lumpy. The exhaust pipe connected to cylinder 2 is much hotter than the others so ill investigate this further ..
