Question about 2000 Yamaha DT 125 R

1 Answer

Replaced throttle cable on pw50 but can't seem to get it adjusted

My product wasn't listed so I just picked one! Checked and double checked that it was the correct cable. The slide in the carb isn't hanging up. When I twist the throttle it doesn't snap back. The cable has too much slack from the throttle tube to where the cable goes into the housing to connect to the carb cable and oil injection cable.

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.

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.
