Frequently Asked Questions . . .
This page is designed to help answer questions a new bike owner may have about his or her Harley Davidson or custom bike. Many of these questions can also be answered by referring to your owner’s manual.
Q: How often should I change my motor oil and oil filter?
A: It is recommended that the motor oil and filter be changed every 2,500 miles with conventional oil and every 5,000 miles if using synthetic oil.
Q: What weight and type of oil should I use?
A: Acme Cycle recommends 20/50 wt. most of the year, but straight 50 wt. over 90 degrees Fahrenheit. You must use a quality oil formulated for air- cooled motorcycle engines. There is a difference; motor oil formulated for cars or liquid cooled engines have a different additive package and will cause excessive wear in your motor. We feature Lucas oils.
Q: Can I use DOT 3 brake fluid in my Harley or custom bike?
A: Definitely not! Only use DOT 5 or DOT 4, depending on the year of your bike. If you accidently put DOT 3 brake fluid in your bike, the entire system should be flushed with denatured alcohol and replaced with DOT 5 or 4 immediately. The reservoir cover of your master cylinder will tell you which DOT you need to use for your bike.
Q: I use regular gasoline in my car. Can I use the same grade in my bike?
A: It is recommended that you use only high test (91 octane) in your motorcycle. By using a lower octane gasoline in your bike, you are more likely to cause pinging and have less than optimum performance.
Q: How often should I have a service done on my bike?
A: Acme Cycle recommends the following:
. New bikes – first service at 1,000 miles
. Regular services should be done every 5,000 miles.
