I have been speaking to a few folk about the oil delivery and found that the early engines were prone to cavitation. To make the best out of the oil supply issues so I can rev to 8k plus the scavange has been opened out to 12.5mm the main oil feed from the cam shaft bush housing to the back of the main bearing housing was also opened out to 8mm .
The oil pump rotors were slimmed down by 4mm to reduce the flow rate a new pump end plate was machined (cheers Dove) with a 4mm spigot on the rear to take up what was removed this all helps increasing the pumping efficiency. Sump baffle made also as this is in a sidecar and not a solo.
I Had top make a spring compressor as well, I have to fit restrictors to reduce the damper stroke and being 30mm long there was no way I ould have forced the spring down that far to get the buggers in. Kinlochleven wont happen for me this year work has got in the way and have finally run out of time.
