April 21, 201016 yr 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?????
April 21, 201016 yr 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.
April 21, 201016 yr 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. Cheers, Stork
April 22, 201016 yr 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
