| + | ===== W Cams - '04-later version used in '91-'03 Engines ===== | ||
| + | |||
| + | 'W' Cams were stock on the 1998-2003 Sport model only. They were also stock on the 1200 engine models from 2004-2006 (not the 883s). Then they became stock on all models from 2007-later. | ||

| + | |||
| + | The #2 cam on the left is machined for the timing cup and therefore will work in 91-03 bikes. The #2 cam on the right can only be used in 04+ (crank trigger) bikes, unless someone does the machining. | ||
| + | |||
| + | Even though they went to crank trigger in '04, they continued to ship the bikes with cams that were machined for the timing cup, for awhile. So there are W cams from 04+ bikes floating around out there that can be used in 91-03 models. Always check to be sure.
