Turns out I have a slow leak in my GasGas's rear tire. Been spraying the rims, spokes and valve with soapy water, but haven't found it yet. Well....I did find that the valve was leaking and replaced it, but it must be leaking elsewhere. Just wondering if Slime is a good idea since the tire is still in great shape? Downsides, besides the mess when you get 'round to replacing the tire? Thanks!
