New owner needs help

[Demps]

First off thanks for all the help I've found just reading this forum. I  bought a 2005 zx 50 about a week ago, seemed to be running fine at first. Then after coming over a high bridge the engine bogged down. I was able to drive a short distance farther to a gas station. After that it starts fine and idles ok but stalls when I give it gas.

Also, how do I know if I am restricted? Bike registers 47 mph on the speedo but 42.5 on gps. Would like to get 5 more mph out of it to keep up wih traffic where I live. Any help is appreciated.

That sounds like it is derestricted, the restricted ones only go 30.

The bogging out has to be fuel related. Try opening up the gas cap and
see if it runs OK. There might be a kink in the vent line.

The other possibility is the intake from the carb to the  motor has come loose.

Thanks, I'll have some time to get into it tomorrow and see how it goes. It was running fine, the problem started suddenly after going up and down a high bridge at full speed so maybe something did shake loose.

Got it back running. Not sure what the problem was but it is gone after a tear down and cleaning of the carb also set the air and idle screws per Naughty Lee's instructions.

MotoRandy you were right, the wires are spliced on the CDI.
