[QUOTE="Marcus Bowden, post: 123427, member: 3287"] My rocker oil feeds are on maximum all the time and I have a reasonable indication with visual sight glasses (plastic tubes) to each rocker. The original metering screws have been removed but there is primus stove pricker hole metering the flow. The pump body drilling has been used to fix a plastic tube to that is before the rocker orifice that is 0.6 mm diameter so it indicates pump pressure. The plastic pipe is extended to the handlebars where it is plugged off, later to be fitted with a clear volumes container so it should fill and keep a visual reading, at the moment of startup it rises to about mid tank level but drops to engine top-level, when warm. difficult to observe. Hence the reason my "B" has a gauge at the handlebars that registers 14.7 psi. (1.0 bar), with the slightly bigger Honda pump now fitted that feeds the cam rail with a control valve to adjust pressure with surplus going to B/end as the temperature fluctuates also double start Pickador pump. PCV did mention in one of his wrightings that he should have kept the gear pump. last tappet adjustment was when I had my stainless pipes made by Chris Knibbs NZ before that was early 2016, then 2500 miles Route 66 then about the same in Tasmania and then 1200 doing NZ riders rally 2017, prior to the NZ national annual Chris K had my pipes off as it's only necessary for the front inlet to adjust tappet. then it was insignificant to record, so I consider it's very good and ready to go again when Vincent wants to pick it up? Haven't cleaned it as the oily patina keeps it in good condition, but my "B" is ready to go as it was fitted with new plugs oil change and a wash off & polish, see my shoes in the timing cover. bananaman [ATTACH type="full" alt="IMG_2349 2.jpeg"]35806[/ATTACH] OIL PIPES ALTERED SO I COULD FIT SECOND PLUG, ROCKER PIN HEXAGON REDUCE SO A SMALL SPANNER WILL FIT MORE EASILY 1/8th BSP BANJO BOLTS WITH 3/8"A/F [ATTACH type="full" alt="IMG_2351.jpeg"]35807[/ATTACH] PLASTIC TUBE UP BETWEEN CABLES & PLUGGED OFF [ATTACH type="full" alt="IMG_2352.jpeg"]35808[/ATTACH] "B" CONSUL WITH TURNING BANANA AMP & VOLTMETER PLUS THE PRESSURE GAUGE SAME CAMS FOR OVER 300K [ATTACH type="full" alt="IMG_2348.jpeg"]35809[/ATTACH] SAME CARB JET FITTED BUT CAN BE SHUT OFF WITH VALVE, BALL BEARING REMOVED AS IF HONDA PUMP FAILS THE BALL WILL LIFT AND SUPPLY A DRIBBLE TO THE CAMS ! !
