2017 Yamaha TT-R230 Owner’s Manual

The 2017 Yamaha TT-R230 was a versatile and easy-to-use off-road motorbike that was made to make trail riding fun and easy for riders of all skill levels. This bike was powered by a stable 223cc air-cooled four-stroke engine. It also had an easy-to-use electric start, quick handling, and forgiving suspension, so it could go over a variety of terrains. With its lightweight design, easy ergonomics, and focus on ease of use, the 2017 TT-R230 was a great choice for both new riders who wanted to learn how to ride off-road and experienced riders who wanted a reliable and fun trail buddy.

Periodic maintenance and adjustment

Removing and installing the panel
The panel shown needs to be removed to perform some of the maintenance jobs described in this chapter. Refer to this section each time the panel needs to be removed and installed.

Panel 

• To remove the panel: Remove the screws, and then take the panel off.
• To install the panel: Place the panel in the original position, and then install the screws.

Checking the spark plug
The spark plug is an important engine component, which should be checked periodically, preferably by a Yamaha dealer. Since heat and deposits will cause any spark plug to slowly erode, it should be removed and checked in accordance with the periodic maintenance and lubrication chart. In addition, the condition of the spark plug can reveal the condition of the engine. The porcelain insulator around the center electrode of the spark plug should be a medium-to-light tan (the ideal color when the vehicle is ridden normally). If the spark plug shows a distinctly different color, the engine could be operating improperly. Do not attempt to diagnose such problems yourself. Instead, have a Yamaha dealer check the vehicle. If the spark plug shows signs of electrode erosion and excessive carbon or other deposits, it should be replaced. Before installing a spark plug, the spark plug gap should be measured with a wire thickness gauge and, if necessary, adjusted to specification. Clean the surface of the spark plug gasket and its mating surface, and then wipe off any grime from the spark plug threads.
TIP: If a torque wrench is not available when installing a spark plug, a good estimate of the correct torque is 1/4–1/2 turn past finger tight. However, the spark plug should be tightened to the specified torque as soon as possible.

Engine oil and oil filter element
The engine oil level should be checked before each ride. In addition, the oil must be changed and the oil filter element cleaned at the intervals specified in the periodic maintenance and lubrication chart.
To check the engine oil level

1. Place the vehicle on a level surface and hold it in an upright position. A slight tilt to the side can result in a false reading.
2. Start the engine, warm it up for several minutes, and then turn it off.
3. Wait a few minutes until the oil settles, and then check the oil level through the check window located at the bottom-right side of the crankcase.
   TIP: The engine oil should be between the minimum and maximum level marks.
4. If the engine oil is below the minimum level mark, add sufficient oil of the recommended type to raise it to the correct level.

To change the engine oil (with or without oil filter element cleaning)

1. Place the vehicle on a level surface.
2. Start the engine, warm it up for several minutes, and then turn it off.
3. Place an oil pan under the engine to collect the used oil.
4. Remove the engine oil filler bolt and drain bolt to drain the oil from the crankcase. NOTICE: When removing the engine oil drain bolt, the O-ring, compression spring, and oil strainer will fall out. Take care not to lose these parts.
5. Remove the oil filter element drain bolt to drain the oil from the oil filter element.
   TIP: Skip steps 5–9 if the oil filter element is not being cleaned.
6. Remove the oil filter element cover by removing the bolts.
7. Remove the oil filter element and O-ring.
8. Check the O-rings for damage and replace them if necessary.
9. Clean the oil filter element with solvent, and then install it.
   TIP: Check the oil filter element for damage and replace it if necessary.
10. Install the oil filter element cover by installing the bolts, and then tightening them to the specified torque.
    TIP: Make sure that the O-rings are properly seated.
11. Install the engine oil drain bolt, and then tighten it to the specified torque.
12. Install the engine oil filter element drain bolt, and then tighten it to the specified torque.
13. Refill with the specified amount of the recommended engine oil, and then install and tighten the engine oil filler bolt.
    TIP: Be sure to wipe off spilled oil on any parts after the engine and exhaust system have cooled down.
    NOTICE
    • In order to prevent clutch slip-page (since the engine oil also lubricates the clutch), do not mix any chemical additives. Do not use oils with a diesel specification of “CD” or oils of a higher quality than specified. In addition, do not use oils labeled “ENERGY CONSERVING II” or higher.
    • Make sure that no foreign material enters the crankcase.
14. Start the engine, and then let it idle for several minutes while checking it for oil leakage. If oil is leaking, immediately turn the engine off and check for the cause.
15. Turn the engine off, and then check the oil level and correct it if necessary.

NOTICE: After changing the engine oil, make sure to check the oil pressure as described below.

• Loosen the bleed bolt.
• Start the engine and keep it idling until oil flows out. If no oil comes out after one minute, turn the engine off immediately so it will not seize. If this occurs, have a Yamaha dealer repair the vehicle.
• After checking the oil pressure, tighten the bleed bolt to the specified torque.

Cleaning the air filter element
The air filter element should be cleaned at the intervals specified in the periodic maintenance and lubrication chart. Clean the air filter element more frequently if you are riding in unusually wet or dusty areas.

1. Remove the air filter element case cover by removing the screws, and then pulling it outward and sliding it forward.
2. Pull the air filter element out of the air filter case.
3. Remove the wing nut and washer from the air filter element.
4. Remove the sponge material from the air filter element frame.
5. Clean the sponge material with solvent, and then squeeze the remaining solvent out.
   WARNING: To avoid the risk of fire or explosion, do not use gasoline or sol vents with a low flash point.
   NOTICE: To avoid damaging the foam material, handle it gently and carefully, and do not twist or wring it.
6. Apply oil of the recommended type to the entire surface of the sponge material, and then squeeze the excess oil out.
   TIP: The sponge material should be wet but not dripping.
   Recommended oil: Yamaha foam air filter oil or other quality foam air filter oil.
7. Pull the sponge material over the air filter element frame.
8. Install the washer and wing nut, and then insert the air filter element into the air filter case.
   NOTICE: Make sure that the air filter element is properly seated in the air filter case. The engine should never be operated without the air filter element installed, otherwise, the piston(s) and/or cylinder(s) may become excessively worn.
9. Install the air filter case cover and screws.

Cleaning the spark arrester
The spark arrester should be cleaned at the intervals specified in the periodic maintenance and lubrication chart.
WARNING

• Always let the exhaust system cool prior to touching exhaust components.
• Do not start the engine when cleaning the exhaust system.

TIP: Make sure to select a well-ventilated area free of combustible materials to clean the spark arrester.

1. Remove the tailpipe by removing the bolts, and then pulling it out of the muffler.
2. Tap the tailpipe lightly, and then use a wire brush to remove any carbon deposits from the spark arrester portion of the tailpipe and inside of the tailpipe housing.
3. Insert the tailpipe into the muffler, and then install and tighten the bolts to the specified torque.
   TIP: Make sure to align the bolt holes when inserting the tailpipe.

Adjusting the carburetor
The carburetor is an important part of the engine and requires very sophisticated adjustment. Therefore, most carburetor adjustments should be left to a Yamaha dealer, who has the necessary professional knowledge and experience. The adjustment described in the following section, however, may be serviced by the owner as a part of routine maintenance.
NOTICE: The carburetor has been set and extensively tested at the Yamaha factory. Changing these settings without sufficient technical knowledge may result in poor performance of or damage to the engine.

Adjusting the engine idling speed
The engine idling speed must be checked and, if necessary, adjusted as follows at the intervals specified in the periodic maintenance and lubrication chart.
TIP: A diagnostic tachometer is needed to make this adjustment.

1. Attach the tachometer to the spark plug lead.
2. Start the engine and warm it up for several minutes at 1000–2000 r/min while occasionally revving it to 4000–5000 r/min.
   TIP: The engine is warm when it quickly responds to the throttle.
3. Check the engine idling speed and, if necessary, adjust it to specification by turning the throttle stop screw. To increase the engine idling speed, turn the screw in direction (a). To decrease the engine idling speed, turn the screw in direction (b).
   TIP: If the specified idling speed cannot be obtained as described above, have a Yamaha dealer make the adjustment.
