I was running my brand new motor and noticed its smoking from the engine somewhere, is this normal also the exhaust sparks, like the actual tube of the exhaust sparks...ground issue or what? So confused I know nothing of these little 2 strokes 66cc's (Skyhawk GT5)


Thanks in advance for helpin a worried noob!!

If it's a painted engine, I don't doubt it might smoke for awhile (crappy paint), mine did. Can you see any tattle tale traces of oil on the engine, it will look black, might be that. As far as exhaust...grounding has nothing to do with it. I suspect that with the hot gases (Exhaust) that it might be burning some material left over from production. Gets hot and when it exits the pipe it looks like sparks. If you took steel wool heated it and forced air on it you'd have the same results.

Your title mentions "How to tell if you blew a gasket" but nothing in the body. The only gasket you can "blow" is the head gasket. To check, either take a compression test or remove head and visually inspect it. The other gaskets can get burned out or disintegrate.

9 times out of 10, a new engine will smoke when first started (smoke externally0.
this is because the engines are covered in a light film of machine oil to protect them while they sit waiting to be shipped.
If you are getting sparks out of your exhaust, it could be loose material in the pipe that is falling off when it gets good & hot.
This is not uncommon because the chinese welding process isn't as good, and there will be lots of slag (debris) left over from the welding.
If the sparks are coming from your exhaust externally, it can be the same thing...welding slag.
but if your pipe is getting that hot, you may have a fuel-air ratio problem..running too lean.
but since you don't know anything about these engines, that may be too in depth right now.
you are mixing 2 stroke oil into your gas at a ratio of 16:1 or 20:1 right?
 
I just dropped a 80cc on my bike New Mixed mine 50:1 just to be safe...I must be having a to rich or you say to lean if she has sparks coming out????

Id like to know whats up with these sparks..It was just a open header it pretty broke in 2 tanks and still some sparks so is this getting too hot and need to be lean more or should I rich en it up?I'm almost sure I don't have any air leaks

Scaring me..:cry:
 
What do you mean the exhaust tube sparks? like sparks from a campfire or electrical sparks?
where are the sparks at?
common for the head/cylinder mating surface to be uneven which allows more oil to seep out and wind up smoking if you are running hot. Plane them on sandpaper on glass.

I had a intake manifold on in so i could slip my pipe on and took it out and it had a few sparks fly out when you gas it up,mill the head first ay?
 
60:1 :eek:

Is that a wise choice?

for any air cooled engine, especially for a bottom of the barrel Chinese air cooled engine with poor metallurgy and unstable thermal dimensionality?
