I installed this squeeze bulb primer on my sled, and absolutely love its usefulness! The only problem is the terrible quality. In less than a week, the bulb was leaking where the rubber contacts the plastic. I did an easy fix of a zip tie on each side to seal. Worked great for almost one short riding season. Then the stock wire band that is supposed to seal the bulb cut into the rubber. Also, the rubber started cracking. Gas now leaks through the cracks and holes in the rubber. I cannot overemphasized the usefulness of this product. I ride a Pro X and always have to yank the carbs to change jetting. With this product, you never have to pull the sled over a billion times to get gas in the carbs. A couple primes and starts first pull. Unfortunately, I now have to look elsewhere for a squeeze bulb primer until Dennis Kirk stocks a quality one, or MFG changes to a better rubber and better method of sealing. I am not willing to use a product that leaks gas on my sled... the last thing I want is leaking gas igniting on the hot exhaust and burning up my beautiful baby. Please Dennis Kirk, stock a quality bulb.
