I have been messing with a cheapo 66cc ebay engine on a friends bike. It was around $59 on ebay so I figured why not take a chance. I put about 200 miles on it and it functioned quite nicely. No problems or complaints really.
A few weeks back I bought a grubee skyhawk gt5 to see how it compared to the ebay generic motor.
I just got everything swapped out and took it for a little spin. It fired right up so I idled along for a couple blocks and took it up to mid throttle. Torque, sound, vibration seemed pretty much identical to the ebay motor.
Now here is the interesting part. I was a few blocks down the road and noticed a bit of smoke rolling off the motor so I went back home to check everything out. I let it idle in the garage for a couple minutes and smoke really started rolling off the thing. So I shut it off and the entire bike is covered in oil and gas and the garage floor is an oil slick.
I let it cool down and checked everything externally and didn't find anything wrong so I pulled the head off and think I found the culprit. There is no head gasket on this thing! Is that right? this should have one right? It idles and revs and runs fine, it just throws more gas on the bike than in to the motor I think.
I guess I am going to need to run in to town and get something to make a gasket. Any suggestions? Would copper RTV work?
I'm not worked up or anything. I just think it's funny that this motor was advertized to be a cut above the rest of the ones out there. I'm not seeing it thusfar, I will have to take another assessment once I get the leak fixed and get it broken in to see if it has any more power or is smoother than the $59 ebay motor.
