I have a Z-400 and I heard that synthetic oil is good and bad. I heard that synthetic oil makes the clutches slip. Is this true. I hope somebody can help me out. Thank You [img]i/expressions/face-icon-small-confused.gif[/img] Text

 

i have been using syn oil for about a year and NEVER noticed any cluch slipping.and the riding up here in mass is horrendous on a clutch due to all the rocks

 

After the initial break in I run klotz sythentic, I have no problems with slipping.
