slaw1967 Posted March 12, 2009 Share Posted March 12, 2009 Can anybody help, i have just purchased a 1989 yb100 and want to know if its ok to put unleaded in. The last bike i had was a fs1e which was a long time ago and ran on leaded. Or do i need to put LRP in. Thanks Simon. Link to comment Share on other sites More sharing options...
Moderator mervin Posted March 13, 2009 Moderator Share Posted March 13, 2009 unleaded is fine the problem with unleaded comes from the valve seats wearing in 4 strokes, 2 strokes do not have valves so no problem, in fact most japanese engines since the mid seventies have been capable of running on unleaded merv Link to comment Share on other sites More sharing options...
