Shop parts for a 2017 Beta 390 RR Dirt Bike!
Keeping your 2017 Beta 390 RR running at peak performance starts with routine oil changes. The 390 RR requires attention to both engine and transmission oil – a unique design among dirt bikes. This step-by-step guide is tailored for MotoSport riders who trust their bikes on demanding trails and races.
What Makes the 2017 Beta 390 RR Unique?
- Duel lubricant system: Separate oil for the engine and transmission reduces contamination and wear.
- Sight glass oil check procedure: Beta specifies oil checks with the engine running, which is different from most bikes.
- Specific oil capacities: Correct volume is crucial for longevity; overfilling or underfilling can cause serious issues.
Tools & Supplies Needed
- Correct type and amounts of engine and transmission oil (refer to your owner's manual or MotoSport parts)
- 2 drain pans
- Socket set and torque wrench
- Oil filter and O-rings (replace as needed)
- Clean rags
- Gloves
Oil Change Intervals
- Beta recommends changing oil every 10 hours for racing, or as often as conditions demand for trail riding.
Step-by-Step Oil Change Instructions
- Warm up the engine to allow the oil to thin and suspend contaminants – run for 2 to 3 minutes, then turn off.
- Stabilize the bike upright on a flat surface with a stand.
- Remove both engine and transmission drain bolts and let the oil drain completely into separate drain pans (one is located under the engine, the other typically on the opposite side).
- Replace the oil filter (if part of your scheduled maintenance): Open the oil filter cover, swap in the new filter and new O-rings, and resecure the cover evenly. Use manufacturer torque specs.
- Clean and reinstall drain bolts with new crush washers or O-rings as needed. Tighten to 20Nm as specified by Beta.
- Refill the engine and transmission fluids separately:
- Engine oil: Add 750-800 ml of the specified engine oil. Pour slowly to avoid overfilling.
- Transmission oil: Add 750-800 ml of the correct transmission oil.
- Check the oil level:
- Engine side: Start the engine and let it idle for 2 minutes. With the engine running, the sight glass oil level should be about midway in the window. Check with the bike upright—this is a Beta-specific procedure.
- Transmission side: Check using the inspection cap; oil should touch the bottom edge of the check hole.
- Top off as needed, but do not overfill. Let the bike sit, recheck for leaks, and ensure levels are correct after cooling.
Model-Specific Tips for the 2017 Beta 390 RR
- The oil sight glass reading can vary after riding; it is normal for levels to settle lower than initially filled.
- Never trust only the window after first fill; use measured volumes for best results. Manual sight glass checks may not be fully accurate due to design quirks.
- Always replace both engine and transmission oils in separate procedures; do not mix fluids across compartments.
When to Replace the Oil Filter
- It is good practice to replace the paper oil filter every oil change for optimal engine protection, particularly during break-in or after heavy use.
Rider's Note
- Keep spare oil, filters, and washers in your ride kit – the 390 RR's performance depends on diligent maintenance. Check MotoSport's dedicated Shop parts for a 2017 Beta 390 RR Dirt Bike! for everything you need before suiting up for your next ride.
