[QUOTE="Rodp, post: 911488, member: 60389"] Hello, I just recently bought a brand new Yamaha YZ125. For break in they told me to mix premium gas 15:1....for a few short half throttle runs....stoping to let it cool in between. Then crack it open for a short run. Drain the fuel and the refill with 30:1. Did that a I have only had about 16 hours use and have gone through 4 plugs. Fouled wet oily black . Is this normal??? B9EG is the recommended plug. I do some trail riding but I am always cracking it open. Yamalube I was told for the break in and then Belray for the life. Will I always have to carry a plug wrench and screwdriver? Will using a BR9ES make any difference? Do I mix the fuel-oil mixture leaner...say 35:1. Can this prematurely wear the engine? Need help. Thanks. Rod [/QUOTE]
