This is a quick and easy way to keep you KTM 400/450/530 XCW/EXC running better and remove all of those emissions canisters along with rerouting the Breather Hose for Racing Conversion. This is the same stuff we use on the Factory KTM race bikes. Kit includes OEM quality hose, 7075 Aluminum Carb plug, sealing washer, & Cylinder head plug.
Remove small hose and fitting from Cylinder Head. Replace with small bolt and loctite in.
Remove Crankcase breather hose from Carburetor. Remove Brass fitting from Carburetor and Replace with Plug. Make sure to loctite.
Remove the old breather hose completely and replace with new one. Run the hose out the bottom of the frame with the carburetor vent lines. It may be necessary to cut the hose shorter so that it isn’t handing down too far below the frame. Remove the emissions canister if equipped.
