my 5 year old daughter is having trouble twisting the throttle on her 2000 pw50,it does fell a little stiff.should i lube throttle cable and is thier a lighter return spring i can put on it
Yes, lube the cable, but also take the throttle tube off of the bar and clean it out and clean the bar. When you reinstall it, push it all the way on the bar, then pull it back off about 1/16"-1/8" before you tighten it down. When it works properly, it should snap back pretty quickly when you let go of it
