Tighten up! We are sure someone of the older generation has shouted this at you at some point or another. Whether it was in jest or you needed to pull it together, there is nothing quite like that terminology when it hits you for the first time. A lot of us were honestly confused as to what we were supposed to do. When it comes to your golf cart, keeping things tight can be the difference between running or not. Parts like the 4-Cycle Yamaha Exhaust Valve will strip a caddie of its ability even to turn the wheels when it blows out. Ensure that if your coach is in for a rebuild, this component is not forgotten. This is not one you can live without. Come to think of it, that list is pretty short.This golf cart valve is not a part you should buy on its own. The only good time is when you are missing it from a more extensive Yamaha rebuild kit. There are a lot of things that need to be replaced right along with this part. Call an expert at Buggies Unlimited to find out what you need.
