Is it an oil leak (darkish & oily coloured, slippery/oily to the touch); a coolant leak (Fluro orange, yellow, green, or maybe even blue); gas (often almost clear as a leak, but it has a distinctive smell!

); or a brake fluid leak (thinner & lighter than an oil leak, but very likely still darkish, unless it's been changed recently)?? :dontknow:
You should also try to identify where it's coming from, as that will make a difference. A couple of sheets of white-ish paper under the bike while it stands &/or runs for a bit should help narrow it down a bit, but you're going to hafta remove the flat tray thingies underneath & take the tupperware off the sides eventually, so do it now & have a bit of a look. :thumbup:
Over to you for more info.... :cheers:
