nubee1974 Posted September 19, 2012 Report Share Posted September 19, 2012 Could somebody point out what is wrong with my bike please? I've taken the carb off to clean it and on the outlet side it has a white residue in it. It continues into the boot that connects it to the reeds. It's fairly solid white like its been combusted onto it. I've no idea but it doesn't look good!! Quote Link to comment Share on other sites More sharing options...
axulsuv Posted September 20, 2012 Report Share Posted September 20, 2012 Could be ethanol residue ??? Quote Link to comment Share on other sites More sharing options...
dbell Posted September 20, 2012 Report Share Posted September 20, 2012 Corrosion????: Oxide of Aluminum, Magnesium or Zinc depending on what metals are in the carb body Ethanol in the fuel attracts water or water leaking or sucked in some other way. Fuel evaporates leaving water to do the corrosion work. Quote Link to comment Share on other sites More sharing options...
nubee1974 Posted September 20, 2012 Author Report Share Posted September 20, 2012 Thanks for your replies Could this have anything to do with me changing over from regular unleaded petrol to super plus unleaded? Should I stop and go back to regular? Cheers chris Quote Link to comment Share on other sites More sharing options...
