I'm also not fond of the small diameter hoses that plumb into the oil pressure switch fitting.
I fabbed an adaptor to allow the use of a braided line, I had lying around. This opens many more possibilities for gauge mounting . Here's a shot of the bits;
I'd like to plumb into the oil fed line, to the head, from the upper case. Problem is, Honda uses a special bolt to attach the line. It looks like a restrictor of some sort is integral with it. The photo below shows the special Honda bolt, on the left, and the longer one I need to use on the right;
I've a few questions: What's the purpose of the 'restrictor'? If Honda wanted to regulate how much oil was sent to the head & crank, why not just bore the center of the bolt to the appropriate diameter? Why have the, small alloy, section hanging down below the bolt? If I use the double banjo bolt do I need to install the 'restrictor into it? Would I risk head/crank damage in compromising the orifice(s)?
If I install the 'restrictor' onto the double banjo bolt can I expect the gauge to give an accurate pressure reading for crank pressure? It won't read lower, owing to the 'restrictor' ?
Thanks, lads, in advance for any insights you might provide.
