BMW R1200RT Valve Adjustments, Valve Clearance Specifications

The Intake valve clearance of BMW R1200RT is 0.13 to 0.23 mm and the Exhaust valve clearance is 0.30 to 0.40 mm.

Regular valve clearance checks are crucial to maintain the optimal performance of the BMW R1200RT Engine.

Whether you have a Hexhead or Oilhead R1200RT, the valve adjustment process remains consistent, emphasizing uniformity in maintenance.

BMW R1200RT Valve Clearance Specs

The BMW manual recommends an engine temperature below 35°C (95°F) for valve adjustments.

The tolerances (cold engine) for both intake and exhaust valves are mentioned below.

For a cold engine, adhere to the following valve clearances:

  • Intake: 0.13 to 0.23 mm
  • Exhaust: 0.30 to 0.40 mm

BMW R1200RT Valve Adjustment Procedure

The valve adjustment process involves finding the Top Dead Center (TDC), understanding cam gear positioning, and utilizing the right tools for measuring valve clearances accurately.

No Oil Drain Needed

There is no need to drain the oil beforehand. Although a small amount may spill when removing the covers, it’s minimal.

Valve cover maintenance during reassembly is essential, ensuring gaskets are correctly placed, and covers are tightly secured.

Check rocker arm gaps and make sure they are according to the specifications.

Precision Finding of Top Dead Center (TDC)

Finding the Top Dead Center (TDC) is a critical step in the valve adjustment process.

While some riders look for a sight hole on the RT for the TDC mark, experts suggest a more straightforward method.

With the valve cover off and spark plugs removed, rotate the engine until the intake valves start to close.

Insert a tool, such as a chopstick, into the spark plug hole to detect piston movement, rotating the engine until there’s no further movement for TDC.

Precision without Sight Hole

For absolute accuracy, the arrow on the timing chain wheel or the lug on the opposite side can be referenced, providing a reliable alternative to the sight hole.

BMW dealers, like Bob’s BMW, offer packs of five color-coded feeler gauges for easy measurement, adding precision to the task.

Cam Gear Arrow and Lug

Understanding the arrow’s or lug’s position on the cam gear is crucial.

The arrow indicates TDC on the right side, while the lug on the left side serves the same purpose.

Choosing the method that suits your comfort level and ensures precision is key.

Get shims from the nearest BMW dealer as they are of the best quality.

Importance of Proper Valve Adjustments

Proper valve adjustments play a crucial role in maintaining the longevity and efficiency of your BMW R1200RT engine.

The engine operates smoothly when the valves are according to the specification.

Loosening the Cam Chain Tensioner

Valve adjustments on the BMW R1200RT involve loosening the cam chain for proper access. You don’t need to remove the cam chain tensioner.

Remove the center bolt and spring, along with the cam caps, and slightly lift the cams to access the shim.

Loosen the tensioner before pulling the cam if a valve is out of tolerance.

When to Get Valves Adjusted on BMW R1200RT?

The recommended valve check and adjustment interval is every 6,000 miles.

Many riders have reported stable valve clearances even up to 20,000 miles without needing shim adjustments.

On-the-Road Considerations and Shim Replacement

If you’re planning a long trip and approaching the 12,000-mile mark, delaying the valve check is a viable option.

If the bike shows any signs of improper valve clearances, stop at a dealer for adjustments.

Shims are replaced only if needed during the valve adjustment process.

Carrying a shim kit with the necessary sizes for potential adjustments on the road is an option, but it’s recommended to check and replace shims during routine maintenance.

Extending Valve and Engine Life in the BMW R1200RT

Regular valve adjustments at recommended intervals contribute to extending the life of both the valves and the engine.

The slow rate of change in valve clearances, especially in Camhead engines, allows for a more relaxed maintenance schedule without compromising performance.

Valve Adjustment DIY Insights

You can check valve clearances on the BMW R1200RT using feeler gauges.

No need to remove bodywork for the valve check, but for the throttle body sync (recommended after valve clearance adjustment), removing the bodywork becomes necessary.

After adjusting valve clearances, consider performing a throttle body sync for optimal engine performance.

BMW R1200RT Valve Adjustment Costs

BMW R1200RT costs usually include the purchase of quality feeler gauges, specialty tools, and replacement shims.

Valve adjustment cost on a BMW R1200RT usually ranges from $120-350.

BMW dealers, like Bob’s BMW, offer tool kits and resources to facilitate the process.

How do I know if R1200RT valves need adjusting?

The following symptoms are seen when R1200RT valve clearances need to be adjusted.

  • Recognize signs of reduced motorcycle performance, especially at higher speeds, indicating potential valve adjustment issues.
  • Difficulty starting or a rough idle are often linked to improper valve adjustments.
  • Loud clicking or tapping noises may signify valve-related problems within the engine.
  • Improper valve settings lead to heightened fuel consumption in motorcycles.
