Andrews pushrods, high lift springs and collars required. BV cams are easy starting and run strong from 2000 to 6000+ RPM with stock hydraulics (1991 to present models need long pushrods). 232653 1986 thru 1990 (BV grind) 232654 1991 thru 1999 (NV grind) 700851 2000 to present (NV grind) The following two grinds were originally designed for the Iron Sportster, Andrews altered the lobes shapes with the correct timing for the different roller diameter and rocker ratio. They are proven cam designs and produce lots of usable power for larger Evolution Sportster engines. V9/N9 CAM KIT Medium lift cams for stroked engines from 80 to 88 cubic inches. Broad torque range to 6000+ RPM with hydraulic lifters, Andrews springs collars and pushrods required (1991 to present models need long pushrods). 232651 1986 thru 1990 (V9 grind) 232652 1991 thru 1999 (N9 grind) 700850 2000 to present (N9 grind) V8/N8 CAM KIT Cams for modified 1100-1200, and stroked 883's with stock springs and hydraulic lifters. Same intake cam as N4 but more exhaust cam duration. Gives great mid-range power. Power range 2000 to 6000 RPM. 232649 1986 thru 1990 (V8 grind) 232650 1991 thru 1999 (N8 grind) 700849 2000 to present (N8 grind) V6/N6 CAM KIT Modified 1200 engines up to 80 CI (1340 cc). Stock springs and hydraulic lifters recommended. Power range 2500 to 6500 RPM. 232647 1986 thru 1990 (V6 grind) 232648 1991 thru 1999 (N6 grind) 700848 2000 to present (N6 grind) V4/N4 CAM KIT Street/Drags, for stock or modified 883, 1100 and 1200 engines. Slightly higher idle speed but stock springs and hydraulic lifters recommended. Power range 2000 to 6000 RPM. 232645 1986 thru 1990 (V4 grind) 232646 1991 thru 1999 (N4 grind) 700847 2000 to present (N4 grind) N3 CAM KIT The N3 cams are specifically designed as bolt-in cams for use in 2004 to present 883 and 1200 Sportsters with stock springs, stock hydraulic lifters and heads. Provide extra power thru the entire RPM range. 232468 2004 to present (N3 grind) V2/N2 CAM KIT Bolt in cams for stock 883, 1100 or 1200 engines. More duration and lift means extra power thru whole RPM range. Stock springs and hydraulic lifters recommended, Power range 2000 to 6000 RPM. 232643 1986 thru 1990 (V2 grind) 232644 1991 thru 1999 (N2 grind) 700846 2000 to present (N2 grind) Andrews has a number of performance cam designs for Evolution Sportster engines. All the cams listed 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 Evolution Sportster cams have stock base circle sizes so stock (non-adjustable) pushrods can be used (except for V9 or BV cams). Adjustable aluminum or chrome-moly steel pushrods are also available as shown (fixed length for 1991). The no. 2 (36 teeth) cam drive gear used in 2000 to present models is not the same as in 1991 thru 1999 models. For this reason separate part numbers are listed for 2000 to present models. Note: 1991 Sportster engines are considerably different than earlier Evolution Sportsters. Cam gears for earlier Evolution Sportsters will not fit 1991 thru 1999 engines. Year 2000 and later models use a different no. 2 cam drive gear as 1991 thru 1999 models. For these reasons different part numbers are listed.2004 and later models have different valve stem diameter and valve springs, installation of cams with more than .515" lift may need different valves, springs and collars. 2070 ANDREWS SPORTSTER EVOLUTION CAMS CAMS FOR EVOLUTION SPORTSTER (Ȧ*ȡ1ȝ 238914 WLDR style cams (OEM 80610-39 & 80611-39 & 80612-39 & 80613-39) 747439 True High Performance, same lobe shape as WLDR but with 10% more valve lift 788730 Stock replacement (OEM 25501-37 & 25502-37 & 25503-37 & 25504-37) Sets of four cams for 1937-1973 45CI (750cc) Flathead engines as used in WL and G models. 27891 CAMSHAFTS FOR 45CI MODELS (Site 483)
