CAMSHAFT - Part Number 114-164
30/46 Timing 256 @.053 duration .490 Valve Lift 52/24 Timing 256 @ .053 duration .490 Valve Lift Slightly higher idle speed but stock springs and hydraulic lifters recommended. RPM range: 2500-6000. Andrews Products has a number of performance cam designs for EV Sportster engines. All of the cams will run to 6500 rpm with stock hydraulic lifters. Since the stock lifters are such proven units, we continue to recommend that they not be changed to solids. Andrews Products EV Sportster cams have stock base circle sizes so stock (non-adjustable) pushrods can be used (except V9 or BV grinds). Adjustable aluminum pushrods are available, but note: 1991 Sportster engines are considerably different from earlier EV Sportsters. Cam gears for earlier EV Sportsters will not fit 1991 engines. The 1991 EV Sportsters require fixed length (non-adjustable) pushrods. Andrews pushrods and Andrews titanium upper valve spring collars will fit all Evolution 80 engines and all Evolution Sportsters. They will provide .050 more spring travel over stock collars and will install with stock keepers.
