Reddit reviews Valvoline General Purpose Amber Grease 1 LB

I run through a can of grease and have to refill my oil can (straight 30 weight) so much more often than my WD40 can. Nothing wrong with WD40, but for most common applications there's a better choice than WD40.

It would help if you could identify the specific joints that are the noisiest. It's likely a combination of your rear shock, your swingarm's connection to the frame, and the subframe joints. Sometimes you can't do much with older bikes short of replacing the parts, but cleaning and greasing it should help you.

WD40 is simply a water displacement. It doesn't grease anything, it just helps remove the water, and it's especially helpful if youre trying to unscrew or pull out something and it's stuck, as it will temporarily lubricate what you spray it on.

If you want to get rid of squeaks in the joints, either get some spray lubricant(like a silicone based one, something like this) or you can tear the bike down and apply grease(just get a tub of it and it'll last you years, something like this) to a lot of the moving parts. The rear shock is something you definitely don't wanna be taking apart unless you know what you're doing, so try just putting grease on the outsides of the joints or getting spray lubricant and spraying it in the joints.

I recommend the grease method, as the silicone spray often doesn't do a long term job and it isn't nearly as water proofing. Try to find some videos of how to take apart dirt bikes, and apply those concepts to your bike. Every bike is different, but if you watch some klx 125 teardown videos, you'll catch on. Pretty much you can take off everything except the rear shock/swingarm and still be able to put it back on easily.

probably a readily available NLGI 1 or 2 ("peanut butter" consistency) general purpose grease, maybe http://www.amazon.com/Valvoline-VV608-Multi-Purpose-Automotive-Industrial/dp/B000GAP43C . A similar grease should be available in pretty much every auto parts store.
