SOURCE: replaced throttle cable on pw50 but can't seem to get it adjusted

If I understand your problem correctly this may help. There should be a spring just a bit smaller diameter than the slide that mounts between the top of the slide and the bottom of the carb cap. No spring means no snap-back. I am assuming there are no kinks in the cable and the cable was routed correctly when installed. Lots of times if the cable is not routed properly the gas tank will "stretch" the cable when the tank is re-mounted. Route the cable properly and the problem goes away..... As far as the slack in the cable, there is a an adjusting screw on the top of the carb (where the cable ends) and an adjuster screw at the hand throttle also where the cable ends. Some bikes have an extra adjuster mid cable but I don't think yours does, (working from memory here). If none of the above work then my guess is that the parts counter handed you the wrong part.

SOURCE: Pw50 starts first time everytime but will not

PW have the stop\start\run switch and will not rev in the start position, there may be a problem in this switch, wire, or the ignition box which controlls this.
The small 50s can also build up carbon in the exhaust port, or the exit end of the muffler.
They also need the original air filter and cover (dont know why, but they wont rev without it).
I realize you may have checked some of these, but not much else goes wrong

Yamaha pw50 replaced card and throttle cables when I move lever from start to run the bike is at full throttle. why????


What is a "card" on a PW50? I have one here and have no idea what part you could mean. My guess with the throttle is that you have the cable way too tight. Check that first - it is quite touchy, since the idel is also st with the cable tension on some earlier models.

How to install throttle cable for c77 motorcycle need routing of the cable


Keep the bends gentle. Go from the grip toward the tank down under the tank to the carb.
You may take the tank off and route cable beside frame. If the old cable is there well follow the same route. After you install cable insure that it works freely.
The other cable will lay beside the throttle cable.
