Honda Mech. Please Help

Energy conserving oil/additives will cause the centrifugal clutch to slip .. As long as it didn't slip to much/long then it probably didn't burn the centrifugal clutch drum .. What I'd do it change the oil a couple/several times using cheap 10w30 letting it warm up good between changes ... Then change it using Honda 10w40 , if it does slip Honda says clean up the inside of the drum using ..

============================================
Centrifugal Clutch Outer Cleaning
Procedure
• Scour/clean the inside of the clutch
outer using a Maroon Scotch Guard
Pad or equivalent, or 220 grit wet/dry
sandpaper and parts washer solvent.
Clean parts prior to reassembly.

So if you use an engine cooling additive to let it run cooler than you are damaging your clutch?

Thank you for the quick response; Estimated runtime when I noticed the slipping was approx 30 min. I just completed 2 oil changes, the last with about 4-5 oz. of motor flush. I purchased Suzuki 4-Cycle motorcycle oil 10W40 (Honda was not available). I will test it tonight in peanut butter. Hopefully Honda quality will prevail. Thank you again and wish me luck, I will keep you posted.
