scotty97 Posted April 21, 2010 Report Share Posted April 21, 2010 My bruv has a 2003 rev3, the bike runs well but after a couple of times out on it, it will be hard work to start, so we take the plug out and it is always quite black and oily. soon as you put a new plug in, it starts first or second kick and runs tidy for a couple more outings. Any ideas???? he using a BP6ES. Some people have said about moving the clip??/ but should we move it up or down????? Quote Link to comment Share on other sites More sharing options...
rij Posted April 21, 2010 Report Share Posted April 21, 2010 hi i have the same on rev 3 200 2001 i've adjusted the fuel screw to 1 1/2 turns out this is a factory setting. hopefully this will sort it. its burning to much fuel and needs more air.

stork955 Posted April 21, 2010 Report Share Posted April 21, 2010 Gday, it depends whether the plug is black and "wet" looking, or "Dry" looking. If wet - too much oil in the fuel, if dry - too rich fuel. For fuel - check air filter, float level and needle position/wear. The mixture screw will only affect idle mixture, not the full range as everyone seems to believe... The UK guys seem to run a 5 plug also.

stork955 Posted April 22, 2010 Report Share Posted April 22, 2010 Gday, a dry looking plug means too much fuel from somewhere. Check - air filter, float level, carb needle and needle jet. Also check you are using the correct plug. Cheers, Stork Quote Link to comment Share on other sites More sharing options...
