Are K&N oil filters good for Harley Davidsons?
Yes -- K&N makes Harley-fitment oil filters with a similar filtration standard to Harley's OEM filters, and they're a common substitute among owners who prefer K&N's larger built-in nut for easier removal during oil changes. Filtration performance between K&N, Harley OEM, and other reputable brands like Hiflofiltro is close enough that brand choice mostly comes down to price and ease of removal rather than a meaningful difference in engine protection.
Can you go 2 years without changing oil?
Not recommended, even on a bike ridden infrequently -- Harley's factory interval is roughly 5,000 miles or annually, whichever comes first, because oil degrades chemically over time even without mileage accumulating, especially from moisture condensation in a bike that sits for long stretches. If a bike genuinely sat for two years, change the oil before riding it regardless of the previous change date.
Does Wix make oil filters for Harley Davidson?
Yes, Wix produces oil filters that fit Harley-Davidson engines, though they're less commonly stocked by Harley-specific shops compared to K&N, Hiflofiltro, or Harley OEM filters. Confirm the specific Wix part number matches your engine's thread pattern and micron rating before installing, since Wix's automotive-focused catalog isn't always as clearly cross-referenced for motorcycle fitment as filters marketed specifically to the Harley market.
How many CCA does a Harley battery need?
Most Harley Touring models spec a battery in the 300-400 CCA (cold cranking amps) range, though the exact number varies by model year and engine displacement -- check your owner's manual or the battery tray label for the specific spec rather than assuming across models. Running a battery below the specified CCA rating risks weak cold starts, particularly in winter.
How often do you change the oil in a Harley 103?
Harley's factory-recommended interval for the Twin Cam and Milwaukee-Eight 103 engines is every 5,000 miles or annually, whichever comes first, for engine oil specifically. Primary and transmission fluid intervals are longer -- typically every 10,000-20,000 miles depending on model year -- since those systems see less thermal and combustion byproduct stress than engine oil does.
Is AGM or lithium better for Harley-Davidson?
AGM remains the more practical default for most riders -- it's compatible with any standard charging system, tolerates a wider range of charger types, and costs less. Lithium batteries are significantly lighter (often half the weight) and hold a charge longer in storage, but they require a charging system and voltage regulator that's compatible with lithium's different charging profile, which isn't guaranteed on older bikes without verification.
What are the three oils to change on a Harley?
Engine oil, primary chaincase oil, and transmission oil are the three separate reservoirs on most Harley Touring models -- unlike a car, these don't share a single oil supply, so each needs its own fluid and its own change interval. Mixing up fluid types (using engine oil where primary or transmission fluid is specified) is a common mistake since Harley's factory-recommended weights and formulations differ between the three.
What is the 12 second rule for motorcycles?
The 12-second rule is a hazard-scanning guideline from motorcycle safety courses: continuously scan the road 12 seconds ahead of your current position (roughly a city block at typical speeds) to spot developing hazards -- a car about to pull out, a pothole, gravel -- with enough time to react smoothly rather than braking or swerving abruptly. It's a scanning-distance rule, distinct from the 4-second rule, which covers following distance to the vehicle directly ahead.
What is the 4 second rule on a motorcycle?
The 4-second rule is a following-distance guideline: pick a fixed point on the road (a sign, a shadow, a pavement mark) and make sure at least 4 seconds pass between the vehicle ahead of you passing that point and you reaching it. It gives more stopping and reaction margin than the 2-second car-following rule because motorcycles are more affected by road surface issues and less visible to the drivers around them.
What is the best Harley for touring?
The Road Glide and Street Glide are the two most commonly recommended Touring models for long-distance riding, both built on the same chassis with the main difference being fairing style (frame-mounted shark-nose on the Road Glide vs. fork-mounted batwing on the Street Glide) and the resulting difference in wind protection and handling feel at speed. The Ultra Limited adds more standard touring equipment (larger fairing, more storage, passenger amenities) at a higher base price for riders who want maximum comfort out of the box.
What is the best motorcycle battery on the market?
Harley's own factory-spec AGM batteries and Yuasa (which supplies OEM batteries to several manufacturers) are the two most consistently recommended options for reliability and correct fitment. For riders prioritizing weight savings, Shorai and Antigravity are the two lithium brands most frequently mentioned, provided the bike's charging system is confirmed compatible with lithium's charging profile.
What is the highest rated oil filter?
Harley OEM filters and K&N's Harley-fitment filters are both consistently rated highly for filtration and build quality, with K&N's larger removal nut being the main practical advantage cited by owners doing their own oil changes. Hiflofiltro is a strong third option, often priced lower while meeting similar filtration specs.
Which motorcycle battery lasts the longest?
Lithium batteries generally have the longest service life -- often 8-10 years compared to an AGM battery's typical 3-5 year lifespan -- because lithium chemistry handles deep discharge cycles and storage without sulfation the way lead-acid-based AGM batteries can. The tradeoff is upfront cost and the charging-system compatibility check mentioned above, since a lithium battery installed on an incompatible charging system won't reach its full lifespan advantage.
Who makes the best oil filter for a Harley Davidson?
Harley-Davidson's own OEM filters, K&N, and Hiflofiltro are the three brands most consistently recommended, with K&N's larger removal nut being the most commonly cited reason riders switch from OEM. Filtration performance among all three is close enough that the choice mostly comes down to price and how much you value the easier-removal nut during DIY oil changes.
