Yamaha R1 7075 alloy oil cooler blocks

A while agao i posted some pics of a pair of oil coller adaptor blocks for an R1 with a promise of a photo of the finished anodised items, well here they are:

They are hard anodised, the customer asked for black on the blocks and clear on the bolt, i think the contrast looks great. When anodising i asked for the threads to be masked off as i didn’t want them treating, its suprising how much threads grow with anodising. The threads in the blocks are taper threads to a specific depth, if they had been anodised it would have tampered with the tollerence and potentially affected their ability to seal correctly.
