This month’s special is fork oil changes. Often overlooked, this regular maintenance task keeps your bike running smooth. Depending on the brand of your bike, your owners manual usually will recommend fork oil changes every 20,000 to 50,000 miles. For instance, Harley Davidson suggests changing fork oil every 20,000 miles. If you’re not sure about your bike, give us a call and we’ll let you know.
If you’re not sure when the last time your fork oil was changed, how do you know it might be time? If the front end of your bike starts to feel too soft or you notice the nose diving when you apply pressure to the handlebars, it could be time for your fork oil to be changed. Another, more subtle, sign is when the forks come back up jerky or too fast, instead of smoothly and evenly like they’re supposed to.
It’s also important to know that there are different weights of fork oil available. The difference is based on the amount of dampening you want in the front forks. If you use a lighter weight oil you will not dampen as much as if you use a heavier oil. In other words, the viscosity of the oil will affect the feel of the suspension.
Harley puts an equivalent oil of 8 to 10 weight oil in the stock shocks. Jan and Sparky will recommend 30 weight oil due to the fact it dampens at a slower rate and your forks will not slam back up. Instead after a bump the forks will slowly return to the original position. This will give the motorcycle more of a European feel and make the bike respond with more control.
Ultimately, the oil used is based on your personal preference. If you change the oil weight and do not like the ride it is as simple as try another weight until you find that sweet spot.
Give us a call to schedule an appointment to change your fork oil and notice the difference in how smooth your bike rides. The month of June, fork oil changes are 15% off!
