Linmax 90 - Fluid types
 

I recently purchased a Linmax Firestar 90CC atv. Wanted to change all the fluids, but wasn't sure what exactly I'm supposed to use. This is a first for me and figured I'd ask. Obviously there's no service manuel for these. Would I use a full synthetic ATV 4 stroke oil (JASO MA2; API SL) 10W30??
Also, rear

shaft driven axel has gears, which looks like the rear differential, which type of oil would I use for this? Perhaps Full Synthetic Gear Lubricant 75W90??
