Posting 3: Well here is my plan for the oil cooler and its lines, and the lines to the cam end caps. Weld the bungs on the clutch side cover, install the banjos and the bolts, and then run (8.5mm ID) lines from the banjo at the rear to the cooler, then from the cooler to the banjo into the crankshaft. The internal line inside the cover needs to be plugged, so the oil will not get confused about where it is going next --- to the cooler --- not the crank. From the oil pressure sendoff I will run a much smaller line (5.5mmID) to a same-sized T fitting to match those on the cam caps, with one line to each. I am going to use only special hose clamps that are designed for this purpose; to hold oil lines on ribbed banjo bolts and not cut the lines; they have rolled edges and a pad beneath the screw threads. I simply do not believe this bike would have had SS lines and red/blue Earl's compression fittings back then. I will restrict the oil at the banjo bolts on the cam caps. The cooler is the same kind that shows up on many of the bevel racers of the 70s, early TT2s, Laverdas, and Peuguots, or whatever that French car is. MikeV

03/10/2017: Flattop has expressed reasonable concern about welding near the site glass. So when it comes to that part more care and planning will be used. Any other experience is appreciated.

Apparently the wheels were turning during all those hours of engine spit polishing.

Not sure what you mean there Mike, and who makes that hose and the fittings?

That was a poorly-written sentence Bill. I have revised it. And I have added a photo of a vintage bevel racer as a (crude) example of what I plan. Honestly, I am not being glib or evasive, but I gathered the parts from a variety of sources, based on 8, 10, and 12mm threads, and lines that would match the parts. The hose was sold to me as high-pressure high (enough)-heat oil hose. The stuff came from scattered sources. Who knows, maybe it all came from China. MikeV

Here is one place some of the parts came from. Great company. So far never missed a beat.

PS: Your recent list of the Brembo stuff is really useful.

Hay Mike I feel like Rip-van-winkle and probably look like him. Woke up to find all this activity on this forum. Interesting project you have started. I want to be your UPS deliverer just so I can peek in the boxes.
The oil line attachment is a little concerning though. Have not seen pantah based machines with slip-on type attachment and I doubt any racing organization would have permitted it back in the day. The oil pressure you will achieve cold on startup is substantially more than what a bevel could make. Check with the manufacturer of the hose and fitting for both working and burst pressure rating. The only ‘factory” hose that wasn’t swaged that I know of is the Cagiva Elefant which had plastic lines to the heads. This however was restricted at the motor exit and not a the heads. Another option might be fitting a later oil pump that has a pressure relief built in. That would work in conjunction with the one between the cases to dissipate the cold start spike. Not sure it could be adapted to the pantah?

Goodridge 910 G Line black hose and black 811 Series fully crimped fittings have an old school look but are plenty safe for oil cooler lines.
