Guys, I have the 80 Skyhawk engine (or I guess the 66cc) on my bike and I have been going thru the break in procedure. I have almost ran 2 gallons thru it (about 4 tanks). I followed the break in procedure by varying the throttle and not going over 15 mph. Here recently I have been opening the throttle a little more and found that it had a terrible bog condition and was a turd. I pulled the carb apart yesterday and found the needle seat and main jet were laying in the bowl. Had I not got a little impatient with the throttle during break in, I would have never known there was an issue the way it ran.
My question now is, how on earth was this thing running that way? It idled fine and seemed to have decent power until I opened the throttle more here recently. It didnt seem to smoke really at all and didn't 4 stroke as far as I could tell. I have read also that during break in, these things could get as low as 60-80mpg, but checking the odometer, I have only gone about 40 miles on two gallons of gas. Does that seem normal? The original plug did indicate it was running rich before I took the carb apart, so I moved the eclip to the second from the top notch and installed a new plug. I took it out for a ride and it was still bogging and thats when I took it apart and found the problem in the bowl. I have that fixed and managed to get 28mph out of it in a short burst and it is running great now. Just curious as to how this this was able to run with the needle seat and jet laying in the bowl. Is 40 miles out of 2 gallons normal during break in?
