Hi all i have blown 10bars air by the place of the oil valve. the plug must be now in the bottom of the crankcase. Sealant piece :confused: ??pressure remains now below 5 bars! And the idle which had fallen to 800 rpm is now at 1300 rpm. Power (lost) = flow X pressure.
I think that the plug was on the comeback from the front head because the rubber O-ring just above the exhaust pipe had a leak. The smelt of the oil dropping on the pipe alerted me... I don't understand how this 7 or 8mm hole can have been plugged. Ihave remove the head and the cylinder and changed the aluminium gasket (which was in the good position

) and the rubber rings.
I have still just one oil cooler in use , the temperature stays under 140°f . Here in Brittanny we have an irish weather!
I believe the girl begins to be reliable: Mikunis Jon mods -a little different, because I have the digiplex system-, new bearings (steering, wheels, starter etc...)
I have repaired the fairings -a lot of work- new paint: :thumbup:
Alain.
