It can easily ruin a day of riding when you're cruising along and suddenly notice oil spurting everywhere around the front of your YFZ450 motor. We show you how to FIX that problem before it happens.

This is the bolt that holds the new billet plug in the head. We would show you the original plug BUT ours blew out on the trail somewhere.

Since this motor originated in a dirtbike, the YFZ's have a place for a manual compression release built into the motor. But since you don't need it, there is a plug put in the hole. Quite a few people (us included) have had this plug blow out while riding. It spews oil all over your leg and the quad, and if you don't notice it in time, it will blow out enough oil to possibly hurt your motor. We recomend you fix it BEFORE it happens to you. GT Thunder makes a billet aluminum plug that can be used to replace the stock one. It takes just one bolt to remove the stock plug, you push in the new billet plug, and put the screw back in. It's as simple as that. The bolt is pretty small, so be sure that you don't over tighten it and snap it or strip the head.
