Hello!

I have a BMW K100RS 4V, and i am Portuguese... this is my first post in this forum!!

My clothes was with smell oil/fuel.

I wish I could help people who have the same problem.
I started by testing the injectors after replacing the spark plugs, then replacing all the pipes of gasoline, when I discovered the real problem. My bike had the engine vent pipe leaking, but mainly the tube that connects the motor ventilation of the air filter box will air intake (buterfly's) was disconnected.
I bought all new tubes Vent hose of my engine, problem solved. My clothes no longer smell of fuel!

Welcome joao.c130
I am surprised that your machine was running at all with air and fuel vapours venting so much. I had that smell once on a long trip and much later found out I hadn't shut the tank cap properly. My leather pants were soaked, but when my radiator overheated later, hot water blew up behind the tank and washed me down.
