Is IT A GXR? OR A orange head generation 5 engine? Like the other gent stated pre heat!!!! for at least first gallon. I like os-p3 plug myself,if turbo and byrons 30%. also the 086 pipe mentioned is fantastic with that engine. If you have the gen 5 engine figure 2 gallons to break in,gxr 1 gallon. For where I'm at in northern ca. I set my needles as follows; lsn-1 turn in from flush,hsn1/2 turn in from flush. I usually take engine apart and clean, then lube,reseal with red atv sealant,start breaking it in!
