SJ50 making funny noises at high speed

Hiya
When my Sj50 gets up to a high speed (50kph+) I often (not always) hear a griding noise coming from the engine. It sounds sorta like a chain grinding. Not a really dangerous sounding rough grinding, but a distinct noise all the same. I don't think it made the noise when I got it 2 months ago.

I ran it on crappy generic mobil 2-stroke oil for most of this time (used about 150ml), but I've recently put Castrol TTS in it. Might this fix it?

I don't really know how to open up the engine to have a look or anything sorry

If it's speed related, the most likely candidate would be the variator. Could be something loose, worn rollers or a belt on the way out...

Sounds like the hampster's wheel needs oiling...

I've decided that it maybe more to do with the engine being too cold, I need to warm it up for a good 3 or 4 minutes before I head out.

But if it's not and I do need to have a look around/oil some stuff, how do I get access to the engine/variator? Do I take the black metal side panel off, or the plastic one on the front wall of the seat?
