I'm confused. I was about to go for a little ride on my first bike the other afternoon of which I have just registered, a rusty but beautiful tiny Kawasaki 2 smoker from the 70s, until I noticed (by looking through the peep window) that it was low on 2 stroke oil. It was a Sunday, I had a blistering hangover, and the bike stores were closed so I thought I'd just go to a Repco or a Super Cheap and pick up any old-school rudimentary two-stroke oil since, I figure, anything too modern might not be the go for this old smoker. After having the attendant put me in a twist - I don't think this tough and burly lass actually knew what she was talking about but she was pretending to - I ended up with 1 litre of Castrol Activ 2T Jaso FC for the ENGINE LUBE and Castrol 2T Self Mix to BURN AWAY. Now, I had a feeling this was wrong, wrong, wrong and I think I was right. So I put the Castrol Activ 2T in the reservoir for the magical rotary valve to mix it with fuel for spark and I left the Self Mix for my Mum's lawnmower. So I ask: - Castrol Active 2T oil is for the fuel mix to be ignited, yes? I did go for a ride after topping it up and the bike ran better than ever which made me quite paranoid but happy. - What oil do I use on the two stroke for LUBRICATION of the moving parts down in the sump area on the right hand side near the rear brake? Opening the rubber cap gives me a view of what appear to be the gearbox, there are cogs and such. I did dip my finger in here and it looked to me to be something like basic engine oil, was tanny/brown colour unlike the mix oil which is bright red. I'm still quite confused by this two stroke business but I love this old cheap piece of junk.
