HRC Camshaft springs and HRC oil pressure relief valve

The continued march through the HRC parts list for the fireblade continues.

I have just picked up a set of exhaust springs for the HRC Camshafts. I am told that the stock items work just as well, decided that should I switch to HRC Cams would use the recommended springs.

I managed to source the uprated oil pressure relief valve. Whilst this is geared to the AMA/BSB/WSB deeper sump they are used in TT bikes with stock sumps too. It seems to me if I am going to make engine tweaks, some time and care is needed with the oil pressure and cooling.

These valves look similar to stock but have a blue dot on them to separate them from the stock item.

Awesome eagle eye headlights

Well I doubt I will ever be brave enough to buy a conversion like this but saw these and the think they look amazing. I find that a great deal of headlight conversion often look tacky and dread it when I hear of angel or demon eyes. These however seem tasteful and do seem to suit the lines of the bike.

New rear suspension link (AKA Dog Bone)

As a fan of making the CBR1000RR that little bit better, I stumbled across a shock linkage from Lee's Cycles.
The Honda CBR1000RR comes with a standard Shock linkage of 175mm. HRC provide these in different lengths (170mm-172mm) to change the handling of the bike.
The Lee's cycles link is 170mm long and is based on the HRC version at a fraction of the cost. 
HRC List 4 different links listed for the blade:
1) 52470-MFL-R10 CONN ROD ASSY., CUSHION R1 (Standard) 2) 52470-NLR-A20 CONN ROD ASSY., CUSHION (MEL) 166.2mm 3) 52470-NLR-A30 CONN ROD ASSY., CUSHION (P2) 178.8mm 4) 52470-NLR-A40 CONN ROD ASSY., CUSHION (P4) 170mm
In Brief, MEL is the most aggressive, P4 is less aggressive, P2 is quite flat and the unlisted is offers the characteristics of the P2 but adjusts ride height.
The idea in general gives better rear grip on the rear and raises the seat somewhat to transfer some weight to the front of the bike. 
Besides the obvious advantages to the handling 5mm means less material and a few…
