Question on rotor lubrication - no throttle input.

[m1tch]

Sometimes you get the Impression that due to only the Apex seals being oiled (on the leading edge) the low rpm Compression/starting is the main reason for the oil, there are a few reasons i say that, the temp normal engine oil works at will be massively exceeded inside the combustion chamber and you have the added problem of deposits on and around the Apex seal/Groove, then as the revs go up the Apex seal uses its own weight to seal at Higher RPM the force often Exceeds the Spring Pressure.

Does anyone remember the Hurley Rotor mod? (they drilled small holes through the bottom of the Apex seal groove into the Oil chamber) all this did was make it smoky and introduced carbon back into the Oil system. I only saw it done on 1 motor.

BTW you can usually tell if you have added too much 2 stroke oil as it will Smoke like an old lawn mower all the time If you use Synthetic 2 stroke oil I’m told (not checked this out myself) that it doesn\'t drop the Octane Level at all. Try Castor oil based 2 stroke oil smells really nice.

Why am I not surprised thats a Hurley engine? :rolleyes:

 Yup, back in the day before all the Imports there was 3 Engine Builders in the UK and there was no Reviews / Feedback

A fun one to try is Castor oil based 2 stroke oil smells really nice.

I have 16L of it, can\'t use it without removing all vestiges of the standard oil though, otherwise it will turn to jelly! :2Confused
