When it comes to routine maintenance, most people don’t think about fuel injectors and fork oil. Dirty or clogged fuel injectors and fuel filters can greatly degrade your motorcycle’s performance and economy. A plugged fuel filter can lower your fuel pressure leading to poor performance and possible engine damage. Plugged injectors can do the same. When it comes to the fork oil, it is just as important to change. Why? Think about this: forks move at a very high rate, sometimes up to 2 meters per second as the fork springs compress and relax. That movement can work dirt and metal debris into the fork oil. Heat, shearing and contamination can take place with all that movement over the course of the bike’s life.
The damping characteristics of old fork oil are very interesting in cooler weather. At first it will resemble cold Maple syrup, not easily stirred. Fork action will be minimal, abrupt and quite harsh. After a few miles the fork oil will begin to warm and change its flow characteristics, providing a little more suppleness to fork travel. That will improve considerably the longer you ride, but only to a point. If you ride for longer periods of time and/or for more miles on your average bumpy roads the fork oil will get thinner and thinner, and then you have little damping to go with your springing.
So, you can see why it is important to change ALL fluids in your motorcycle. We just happen to have 15% off fork oil changes and fuel injector cleaning this month. Stop by or call for your appointment today 636-775-1385.
