Wear levels are low and properly balanced, so we think your engine is wearing well at this point. We did find some fuel dilution, which is common in racing bikes, due to the type of operation they see. We would normally consider 2.5% fuel to be a possible issue, but since we're not familiar with this engine we'll see what the next sample brings. The TBN read 11.6, still lots of active additive left.
