STEP 4: CAP OFF FUEL INLETS, CARB AND EXHAUST
Use an extra antenna cap to seal off the carb’s fuel inlet, and cover the carb opening and exhaust port with vinyl caps. Some engines include these; if your did’nt, visit visit your local hardware store for replacements. If you strike out, Mugen offers a set of four caps (two small, two large) Item number: B0424
STEP 5: CLUTCH-BELL MAINTENANCE
Remove the clutch bell and wipe out the inside with a rag and motor spray. Use a Scotch-Brite pad or 400 grit sand paper to re-scuff the inside of the clutch bell to make a “grabby” surface for the clutch shoes.
STEP 6: INSPECT THE CLUTCH SHOES
Check for worn shoes. Blow the clutch off with compressed air. Clean out the bearings with motor spray, and re-oil with Trinity Royal oil. Use canned air or air compressor (20 psi) to spread the oil inside the bearing. This prevents the oil from being flung into the clutch shoes. If the shoes have burrs on the edge remove them with a file or X-Acto knife
