Orange & Black HD Repair Injection Service
Fuel injected Harley Davidson engines have a tendency to foul injectors and develop drivability problems. Remember, your Harley Davidson engine only has 2 injectors to feed it the fuel that it needs. Stale fuel, long gaps of time between “cruising weather,” and high heat all contribute to poor spray patterns and fouled injectors.
When Good Injectors Go Bad
• Most Harleys are not daily-driven vehicles. Typically, they are driven seasonally and on fair-weather days. As a result, deposits are given more time to harden, and less fuel passes through the injector to help dissolve and loosen them. This leads to bad spray patterns (causing poor idling and/or part-throttle stumbles) as well as decreased fuel flow (less midrange torque and, in advanced cases, less overall power).
• When a Harley is started after being stored all winter, it is often run on old gasoline. As gasoline ages, the lighter, more volatile parts of the fuel evaporate out. This leaves behind heavier, “stale” gas that is more likely to foul injectors. In some cases, the fuel thickens enough to stick or plug the injectors shut, causing a no-start condition.
The Good News
All of the conditions listed above are reversible about 99% of the time. Give us a call to set up an appointment to have your injectors cleaned, restoring them to a like new condition. We use the same Harley-Davidson approved cleaning system and solvent as the dealers use.
