Title: Crank case oil
Post by: Ryan393 on March 18, 2017, 10:46:35 AM

Is it OK to run royal purple 30w with the 125 clutch?

I assume you're asking if it's OK to run this oil in the transmission of a KX125.  This would be transmission oil, not crankcase oil.  The crankcase on a two stroke is lubricated by the oil suspended in the fuel the engine ingests.  That being said, I would NOT recommend this oil.  Why?  Because it's designed for four stroke engines without wet clutches.  Their website doesn't use the term "friction modifiers" to describe this oil, but I wouldn't be surprised if it contained some.  Since the KX has a wet clutch, stick with an oil specifically designed for wet clutch motorcycle transmissions.  I could recommend an oil for you, but that always starts the biggest pissing match, so do some research and decide for yourself.
