[QUOTE="kirrbby, post: 190384, member: 3972"] This thread is from 2012. I don't think those folks drop in anymore. But you can take your dimensions right from your own handlebar... Measure the I.D. Retract the throttle hinge and measure, from the hinge, to the end of the bar. Write it down. Then, spin the throttle to move the hinge toward the end of the bar...measure and write. Make a thicker plug to go against the hinge...thicker, because it needs to stay square inside of the bar, AND slide back and forth with the hinge. Then make a thin plug for the end of the bar... just to back up the spring. Then buy a spring the right diameter, AND capable of springing, long and short, inbetween the plugs...AND, find one with the stiffness that you need to do the job. As a alternative. Get your throttle parts all spiffy new and clean and lubed. Same with the cable. Then, take the slide and spring from inside of your carb to the hardware store. Look for a stiffer spring that will fit and work. [/QUOTE]
