EZ start cams cause low readings, but still equal. HD ACRs will cause a difference front to rear when activated, but should go back to close to even F-R when deactivated.
PS- is it needing a lot more fuel, in one cylinder, than usual?

The guy that owns the bike had friends install it. The place he bought it from drilled the case so that external oil lines wouldn't be needed. Drilling the cases voids the warranty. They also installed a grudge box at the same time. Could never get it to stay running so they gave up and took it to Harley. After 6 months or so at Harley one of the corporate tech guys asked if they'd checked the speed sensor. Turns out with the grudge box there's a spacer that needs to go under the sensor. This wasn't installed so the sensor got chewed up and was shorting everything out. Fried the ecm and caused all these issues. Harley made the repairs for all that and got it running. It was then trailered to me for a tune and here we are.
