• Installing Evo Cams (91 and Up)

• 86-99 - Matched cam gear set includes pinion gear and gearcase cover. (not sold separately)
• 00 - Options increased;
  • Cam gear sets w/ pinion gear,
  • Cam gear sets w/ pinion gear and cover,
  • Gear sets w/ #2 cam and pinion gear (only).

• The #2 “W” cam may or may not have a provision for a timing cup after 03. ⁸⁾
  • If you intend on installing 04-up “W” cams in 03 and prior engines, look at the end of the #2 cam.
  • If it does have a provision for a timing cup, they'll work for prior year applications.
  • But, you'll have to either update your pinion gear, or use a press to swap your #2 cam's drive gear.
  • For 03 and prior year engines, it needs a drilled and tapped hole in the middle of it and the timing cup notch.

• Below, you can see the notch on the cam on the right very easily.

The parts books say the cams are the same from 2000-2006.
Then they changed in 2007, implying that all 2004-2006 cams had the unneeded timing cup provision.
However, people have reported pulling original cams out of these year bikes both with and without it.

Frame mount Evos 1986-2003 do not list a part number for the pinion gear and it appears the pinion gear is part of the (cam gear set).

• The cam bushings get their oil from the fling off of the cam gears and drain back from the top end down the pushrod tubes that puddles in at depressions in the castings where the cam bushing slots are aligned. So basically they are drip fed. Also the cam bushings on the case side are open to the crank behind them, and probably get splash there too. ¹⁵⁾
