Glen's 2017 CVO Street Glide was recently built into a Torque Monster, with a 128Ci Big Bore Upgrade as well as a few other Supporting Modifications.
This bike cam to us with a nicely running Stage 2 engine, it had the TTS-150 Cam and the Fullsac MX Headers already fitted.
While we had this engine apart we updated the factory oil pump to the newer 8 Lobe pump with the main bearing seal as that is a known failure point on these early Milwaukee Eight Engines which can cause them to suck air and lose oil pressure on long rides. This is partly due to their 60/40 Oil Scavenging from the crank case and the sump, with the updated version being a 50/50 split.
