What is this metal (sbt motor)
01SUV with sbt motor 30 hours.
As the title states, trying to decide if this is a foreign object that made it inside or part of the motor. Compression is perfect 134 133 134 warm. Breaks 140 on all three cold. After checking compression and changing plugs went back to the lake and ran her hard. Wot 1-2 mins passes for nearly an hour. If it was a needle bearing I would think I woulda thrown the rod. If it was a piece of ring I would think compression would reflect. Carbs were rebuilt at a shop I drilled the returns at this same time) when my gp1200 got engine work do to a carb issue, plugs are reading good, little rich if anything. Ran for a hour after that, pluged intake resulted in engine overheat protection kicking in. Everything seemed fine after it cooled down tho. This was the first ride since then was testing out ff/chart plotter that I installed over the weekend.
I would normally tear it down and have a look, but being as it is a sbt motor can't do that, going to go show then the metal and see if they want it back before it possibly grenades.

hard to tell from the picture John almost looks like a needle bearing. If you like stop by and bring it i will tell you if it's from the motor.

Just got back from Jim's house, he pointed out that it was painted (sbt paints everything) and we decided it is something that was left in the motor during assembly that finally came loose form w/e it was stuck to. Think I will run to sbt in The morning and see if any welding was done to this case.
