I'm doing a lighting coversion on my 2001 YZ426F. I know the (2000-2002) WR426 / WR450 flywheels will fit, but what about later WR426/WR450 later years? I found a deal on a 2008 WR250 flywheel and stator, but have no idea if a 2008 part will fit on the 2001 YZ426. Or later (2002-2014) WR426/WR450 flywheels? Thanks in advance if anyone knows- BTW I belive my crankshaft is keyed not splined, if that helps.
