01cr 500 my buddy used 10-40 synthetic oil and he burned his clutch down... I told him it’s to slick of a oil and he should use 85wt (the Honda red bottle to be exact).. I just remember I ran synthetic 10-40 in my RM and the clutch felt like it was slipping went back to 85w and it was all good... thoughts/comments

Was it motorcycle specific oil? Many automotive oils have moly in them to help with fuel economy. Moly is not good for oil bath clutches because it has too little friction for the clutch to work properly. A motorcycle specific oil should work just fine. Look for JASO MA/MA2 rated oil.

Tell your buddy that the clutch is fried and will be too expensive to fix.

Then pm me his contact info and I will lessen the blow by taking that POS off his hands for $500.

You are welcome

If the oil says "energy conserving" in the rating circle on the back don't use it.

Walmart base brand does not have molt.

I would use ATF . automatic trans fluid. The cheaper the better. Change ever weekend.

I ran Rotella in the gearbox of my 500 with no issues. Synthetics are okay as long as it's rated for motorcycle applications.

I use ATF in my YZ250 and so far no issues at about 25 hours. Clutch engages more aggressively.

Has science gone too far?

I use WD40. The little red straw that comes on the can, means you don't even need a funnel.

automatic transmission fluid is the answer , back in my days i used that for 6 years ..less problems with my clutch or my gearbox than the 3 years i was using the 85W cream smile

85w "transmission" fluid has a roughly similar viscosity to 10w-40 "motor" oil.

They are just rated on different scales
