Hey there I was surfing through this forum and found a lot of great information on these motor bikes. I have a Shwinn set up with a 69.7cc motor which i think they call an 80cc. It just started knocking and smoking more than usual. I have only had it since the end of Nov. and probably had 1 or less gal. run through it. I used the oil ratio that it called out for for breaking the motor in. When the motor is under a load it doesn't knock but if I'm just cruising it knocks at 1/4 or 1/2 throttle. What may it be? I will attach a link where yo can go and download the movie so you can hear the knock. Let me know what you think it may be. Thanks for any info. I also bought the CDI Jaguar ignition I still need to put on.
