Accelerator Pump Spring [Accelerator Pump Spring [3901]]

Excellent

Oct 21, 2022

Thumbs up!

This pump spring is very durable and the value of product is worth the price of it. After placing on my bike I can tell that the throttle is a little more responsive than it was before..Seems to have helped my mid range from leaning out. Not too hard to install if you have a little carb experience, if not you may want to get some help putting it in. Big upgrade over the zip tie mod and was a perfect fit on my crf250.very happy!
