Post by s***@gmail.comcan i put goop in my motorcycle tyres that already have goop inside?
Probably, if the valve core isn't totally gunked up from the previous goop
injection. Guessing we're talking about 'Slime' or a similar product
being used to stop an air leak, right? Most 'Slime'-type products are
only intended for short-term use, basically just to get you home. If the
tire leaks it should be repaired or replaced.
BTW, people that change tires for a living really, really hate dealing
with 'Slime'-filled tires.
