How To Install a Clutch Kit on a 1984 Suzuki RM250

Why Replace the Clutch on a 1984 Suzuki RM250?

The 1984 Suzuki RM250 is a lightweight twostroke motocross machine where the clutch connects your throttle inputs to acceleration. Common symptoms that mean it's time for a clutch kit include slipping under power, dragging or inconsistent engagement, a spongy or overly tight lever feel, and hard or noisy shifting. Aggressive starts, tight woods work, sand, and highheat conditions accelerate wear on the wet multiplate clutch used on this era of RM250. Replacing the clutch restores crisp throttle response, efficient power transfer, and predictable shift quality.

Overview of the Clutch System on this RM250

This RM250 uses a cableoperated, wet multiplate clutch friction plates alternated with steel drive plates, a pressure plate held by springs, and a clutch basket and inner hub transmitting torque. Important parts to inspect during replacement are the clutch cover, pressure plate, clutch springs, friction plates, steel plates, clutch hub & basket, inner hub splines, thrust washer and pushrod.

Preparation

• Park the bike on a level surface and secure it on a stand so the rear wheel is off the ground.
• Clean the area around the clutch cover to prevent contamination when opened.
• Because this is a wet clutch, place a drain pan under the bike and remove the drain bolt to lower some oil if the cover design requires it. If the cover can be removed without significant oil loss, you can avoid a full drain.
• Gather basic tools socket set, clutch holding tool or a screwdriver for the hub, impact driver if needed, a torque wrench for general reassembly (but don't use modelspecific torque numbers), spring compressor or long socket for even spring compression, and fresh oil plus a new filter if you'll refill.

StepbyStep Removal

Follow a methodical order to avoid surprises.

• Loosen the clutch cable at the lever and free the cable from the perch so the clutch is fully relaxed.
• Remove any external items blocking the clutch cover skid plate, footpeg, or shrouds as needed.
• Take off the clutch cover bolts, noting bolt lengths and placement. Carefully remove the cover expect some oil to leak if not already drained.
• With the cover removed, you'll see the pressure plate held by multiple springs. Use a spring compressor or evenly loosen the springs in a crisscross pattern to avoid warping the pressure plate.
• Remove the springs and pressure plate, then pull out the friction and steel drive plates one at a time, noting the order. Count plates and note orientation friction plates toward the engine, steels alternating.

Inspection What to Look For

• Friction plates check for glazing, excessive thinning, burned surfaces or uneven wear. Light glazing can sometimes be sanded, but deep wear means replace.
• Steel plates look for blueing, warping, and heavy scoring. Warped steels cause drag and harsh engagement.
• Springs confirm they retain free length and show no signs of distortion. Weak springs cause slipping under load.
• Basket fingers inspect clutch basket for notching or grooves where plates contact. Notching causes catching and poor engagement; minor notches can be dressed with a file, severe notching means replacement.
• Inner hub splines check for rounded or worn splines that let plates slip on the hub.
• Thrust washer and pushrod ensure washers are flat and pushrod moves freely; any burrs or wear can alter engagement.
• Oil condition dark, burned oil contributes to clutch wear. If the oil smells burnt or is heavily contaminated, change it when reassembling.

Preparing New Plates

For a wet clutch, soak new friction plates in clean engine oil for at least 15-30 minutes before installation so they accept oil and engage smoothly at first use. Keep steel plates dry and stack them in the order they will be installed.

Installing the New Clutch Kit

• Start by installing the inner components alternate friction plate then steel plate, matching the original count and orientation. Ensure each plate seats fully against the hub and basket.
• Once plates are stacked, fit the pressure plate over them. Compress the springs evenly and start all spring bolts by hand to maintain uniform pressure. Tighten them gradually in a crisscross pattern to ensure the pressure plate sits flat.
• Reinstall any thrust washers or circlips in their correct locations if removed.
• Before dropping the cover on, wipe mating surfaces clean and replace the clutch cover gasket if cut or damaged. Fit the cover and tighten bolts progressively in a star pattern to seal the cover evenly.
• Refill or top off engine oil if you drained it, and replace the oil filter if planned. Use oil appropriate for a twostroke or the RM250's oil system as you normally use for this bike.

Final Adjustments & Checks

• Adjust clutch cable free play to the recommended feel for a twostroke motocross lever a small amount of free play at the lever ensures full engagement without dragging. Check the cable for stretch or binding; replace if frayed or sticky.
• If the clutch lever feels inconsistent after assembly, loosen the cable to increase free play and test again; sometimes a few heat cycles are needed for plates to seat.
• Start the bike and let it warm briefly, then test engagement at low throttleconfirm no slipping or grabbing. Perform a short lowspeed ride to verify shifts are smooth and lever feel is consistent.
• After the first ride, recheck clutch cover bolts, cable adjustment and oil level. Plates may bed in slightly, so a minor readjustment of cable free play is normal.

Performance Notes for Riding

On a 250cc twostroke RM250 used for motocross, a properly installed clutch gives clean launches and predictable power delivery essential for holeshots and technical sections. If you ride in sand or woods, consider more frequent inspections since those conditions increase clutch heating and wear. Also remember oil condition and correct oil type play large roles in clutch life — fresh, correct oil helps avoid glazing and improves engagement.

Closing Tips

• Keep parts organized as you disassemble so reassembly follows the original sequence.
• Replace springs as a set rather than mixing old and new to ensure even pressure.
• If you find severe basket or hub wear, address those parts before reinstalling plates new plates on worn hardware will not cure engagement issues.
