Usually the coolant level is at the bottom of the neck of the fill pipe, any excess will dribble out the overflow when the coolant expands with heat (this is normal). If your mate's bike is still dribbling coolant after riding a bit, it may be that the o-rings sealing the head to the cylinder are leaking and should be replaced. Try re-torquing the head fasteners first to see if that doesn't cure the dribble, if not the o-rings probably need replacing.

tankygsy Posted November 13, 2011 Report Share Posted November 13, 2011 Or replace the rad cap. It's designed to open at 'x' pressure. Quote Link to comment Share on other sites More sharing options...
