Hi All,
I just bought a used YZ400F and it has the Auto decomp. system installed. I've read replies about a TT decomp. Plug. I dont know whats in there now. Could someone please explain to me what it is and where it is located. Everyone has been such a big help here. I've always had vintage 2 stroke bikes and this is my first 4 stroke so I have alot to learn but thanks to everyone here its making the learning process alot easier.

John :naughty:

The plug is located on the right side of the engine at the front just under the valve cover. If there isn't a plug there, then it will likley have the stock decomp arm instead. Check out the TT store, they have pics of the plug there.
