12mm rotorhead with 410 11mm springs

Anybody have info about setting 11mm springs in 107J. Esitronic don't have that information in that pump. How much emphasis can 11mm 410 springs can take and don't damage camplate... I don't have original 107j. Maybe somebody have complete rotorhead and can measure this for me.

don't now i run the orginal 12mm springs with the 12mm pump.

no problems till 5700 rpm

You have good power tillt 5700 or you only rev it that high on lower gears. Have you got any dyno of your engine?

no dyno jet. 3 and 4 gear also 5700 rpm.

Nice i must try it someday rev that high on upper gears ...
