I dont have pictures but I think I melted my plug. I was riding and the bike got hot and then went blaaa and died. I checked the plug and it had a little metal connecting the gap. Not sure how that happend, but I pulled my head off and check it out, it looked good, and the piston was ok, alsot the cylinder walls looked ok.

Any ideas, this was on a 250R.

 

Jesus!! DONT run it! you might be pre detonating the motor making your piston/sparkplug MELT.. whats your compression?? What spark plug you running? What fuel? and are you jetting rich or TOO lean?!?! LEAN IS BAD.

 

THis is on the bike with 160 for compression and .50 over with the power head, and I pulled the head and everything is fine on the inside. The bike used race fuel before I am not sure what mix, I was probably running a little rich at 32:1. SHould I lean it out a little more, or get some octane boost. I heard that octane boost is not always what it seems, but I am new at this, used to running stock at 32:1.

 

oH SMoked,

where do you live in Vancouver, I grew up there until I moved to Alaska when I was 11. I lived in the Orchards area, or 5 corners NE 76th street.
