DO NOT PUT SPEED CRANKS IN WD40
Just a precaution, had my speed apart waiting on bearings and had all internal parts in a ziploc bag that i sprayed lightly with wd to keep moisture out. The silicone in the speed crank absorbed it all and ballooned outside normal dimensions! i have it airing out and seems to have swollen down to normal so justt be careful

Hey Tony (long time since we've spoke last!) I've tested most of these oils that people use for after run and I can tell you that when it comes to Marvel Mystery Oil, at least their Air Tool Oil it will do the same thing if you douse the engine and leave it in there for a while.

We have been using a fuel with rust inhibitor in the fuel and always run the engines dry while warm at the end of a race meet and never in the last 5 years have we had to put and after run oil at all....
I have seen that happen as well the silicon expand and it was from washing in the internals in a wash trough then dried, its like the silicon absorbs the solvents like a kid with a lolly has to have it...lol

I've always used the red stuff and had no issues

Why not just buy a 4 dollar bottle of after run oil that is designed for this actual purpose????

evolution engines makes some good blue oil.

I use either Mineral Oil or Amsoil Synthetic 2 Stroke Oil. The Amsoil worked awesome on the MX bike as well. Miss it big time.

WE have come across this problem quite a bit with the epoxy coming loose or falling out. If anyone ever needs a crank filled feel free to check out our service. $15 for a re-fill using Oem spec epoxy.
