Yamaha Head Decompression Plug BLUE Billet YFZ YZ450F 250 YZ MADE IN USA

Description

This listing is for one BLUE Yamaha Decompression Head Plug that fits many 4 stroke Yamaha quads and dirt bikes. This plug replaces the stock rubber one that has a tendency to fall out and ruin your day of riding, with this one you won't have that problem. The plug goes where the earlier 4 stroke models had a manual decompression system, when Yamaha changed to an automatic system they never changed the head casting and just put a rubber plug in there. We have had one of these on our shop '04 YZ450F since it was new and it has never fallen out, the rubber ones do because the material is not rigged and the set screw will not hold them in, then the pressure blows them out. The plug comes as pictured with the o-ring. Installation is very easy, remove the set screw, pull out the rubber plug, push in the new billet one, re-install the set screw, and you're off to the races! Please verify your model and year is listed below for fitment, and don't hesitate to message us with any questions you might have. Thank you!
