really really stupid question...but

right went to fire up the bike today, and say laying on the floor under it a little black plastic cap on the floor with COOLANT on it....so must be off the bike...but obviously i cant see if the coolant cap is missing....but assuming it is of the bike....they question is....how the HELL do i get it back on!?

The only cooland cap is the one on the rad which is visible.

Post a pic of said item and we will tell you if its off the bike.

Does the expansion bottle have Coolant written on it??? If its fallen off there you need to remove the right tank panel to replace it

yea i thought that, thought it might have come off the expansion tank under the right blade, anyone know if there is a cap on it?

yeah a black one!
