Arlen Ness 15-676 Black Oil Pressure Gauge Kit - Universal Motorcycle & Car Engine Monitoring System for Harley, Honda, Yamaha & More

What you would expect from Arlen Ness. Very good quality materials and billet aluminum looks great. I upgraded my oil pump, lifters and relief valve so wanted to keep an eye on my oil pressure. My mecganic said he puts these on all of his bikes as he doesn't trust the "idiot light" on the dash. There are cheaper oil gauges out there but I'd recommend spending extra for this one as will last as long as the bike!
