Best vacuum gauges in my opinion, and most like original Honda, are Sealey and cost about £135 on ebay plus come with all adaptors. There are similar looking ones costing about £50 but the actual gauges are cheap and will not be as accurate.
Warning light extinguishes at approximately 15 psi and maximum pressure is capped at around 60 psi, estimated slightly as I think they may quote 59.something in manuals. It'll dump excess out the relief valve to avoid risk to oil pump drive, as most engine arrangements do. Flow is, pickup, pump, floods filter housing, exits through filter element centre via main bolt to internal galleries. Pressure relief also built in to filter bolt in case of filter blocking, so feed is maintained with unfiltered. Barrel feed route to head has resistance in line to maintain crankshaft plain bearings in high pressure environment, with cam etc at low pressure open bath type oiling and spray bars for wetting effectively.

I couldn't live with that Allen bolt sticking out! 😣Hi taysidedragon, well spotted. Yes its on the " to do" list, but at least its solid for now until i can source a nice replacement. Any suggestions from your experience please I would try and get a longer knurled bar made to replace the pedal that's too short.For carb balancing I use the Morgan Carbtune set. Well damped and accurate.ThanksDennis

On a 400 there is not room to put anything extra where the pressure switch is(on oil pump under sprocket cover) so you need to drill and tap the screwed in plug under the points cover, just so happens i took one out of a 500 engine on Sunday you can have for post

When I fitted the oil guage to my CR750 Rep, I used a 'tee' off the oil pressure switch pickup point - its a few years since I did it so can't remember gallery thread for the 'tee' but think I searched the US SOHC site. Then worked back from the guage for fittings/pipe
