We took the custom bagger the motor was in and rode it over to Geoff Gaites' Cycledoctor shop for dyno tuning. After dialing in the ignition and the EFI map, the 95-inch motor produced a whopping 120.72 hp with 108.07 lb-ft of torque. But those numbers don't tell the whole story. The chart shows usable street power; at 3K rpm the motor pulled more than 90 lb-ft, rising to peak torque at 5K before a slight leveling-off. This motor has no problem pulling the bagger's front wheel off the ground.
