I was riding my bike today (Grubee Skyhawk) I'm about 1 tank through the break-in and I noticed the nut that holds the front motor sprocket on the engine came loose. Is it ok to use red locktite on this part, and is there a certain torque I should use? or can I tighten it right down?

I wouldn't use red, maybe blue. You may need to take it off sometime and that'll make it a lot easier. I never heard of one coming loose, I think if you tighten it up and use the special lockwasher behind it it should be fine.
A piece of copper, an old penny for instance, can be wedged in the gears on the other side to hold it still for tightening without any damage to the teeth.
The gear noise you hear is common, they're noisy little engines. There's a couple things you can do to cut the noise. A bit of grease (about the size of a pencil's eraser) put on the small gear will work its way onto all the teeth. SBP sells these weird sound deadening things that stick on inside the cover. They're like stiff tar that never hardens and deaden sound. I've had them since day one and I think they work, it's pretty quiet.
Don't overdo the grease, it can work its way onto your clutch plate and pads causing it to slip.
Let us know if your output shaft and sprocket's ok after you tighten that sprocket nut.
I would worry it might have gotten chewed up while it was loose.
Good luck to you!

Im currently having the same issue. I have tighten the nut, but after maybe 100 meters (yes i use the metric system, because. ) the nut gets loose again. And the motor is running but i have no movement. What i need to do then is to push the sprocket in agian, and tighten the nut, but same thing happens all over again. Anyone have an idea how to solve it? Thanks.
Yes, it was the woodruff key that where only crumbs, Good thing was that my engine supplier sent me a new one for free. Now i will try to use loctite and maybe instead of the old spacer, an lockspacer instead. Its a kinda stupid design when the shaft isn't conical. And all the power is on the woodruff key.
