Everybody said we blew the rings dyno'ing this bike at one break-in mile. So before we ran it again, cold, we compression and leakdown tested it - 97 street miles later.
Leakdown: 0% on all four. Compression: 210 / 207 / 204 / 210 - a 2.9% spread, against a 10% spec.
To be precise: there is no such thing as a true 0% leakdown engine. All engines have rings, and all rings have end gaps. 0% means we could not measure any leakage on this gauge.
One correction from the first video: I said these engines are "broken in from the factory." That was sloppy wording on my part. Run and validated is accurate - Suzuki cold-tests every engine and rolling-road tests every finished bike. Minutes, not miles.
We will have a video going through all of this in detail.
