January FAQ's
Q: Do I have to change synthetic oil as often as conventional?
A:Yes, Synthetic oil has proven advantages but replacement intervals aren't one of them. The main reason we change oil is to remove contaminants like metal particles and by-products of combustion, not just because the oil is "bad" or "broken down".
Q: Do I really have to run 91 or higher octane gas in my H-D motorcycle?
A: Yes, low octane fuel is more unstable and "runs hot". H-D engines have fairly high compression ratios and stable fuel is necessary to prevent pre-ignition and/or detonation, which can harm the engine.
Q: If low octane fuel is not good, should I use racing fuel?
A: High octane racing fuel (100+ octane) is rarely ever required in street-legal engines. That stability is usually never necessary and many racing fuels contain lead which can be harmful to engine sensors like oxygen sensors.
Q: Should I change my oil before storage or wait until spring?
A: You should change the oil before storage to remove debris and harmful contaminants that accumulate during normal operation such as metal particles and chemicals resulting from the combustion process.
