2001 - 2003 YZ frame differences?
Posted January 05, 2006 - 09:53 AM
I know the 2003 did not have an oil filler at the top of the frame like the 426 did. And I see that there is an oil filter unit at the bottom of the frame down tube for the 2003 450 frame which looks to be in the same place as the 426 frame.
Does anyone know for certain if the engine mounts are the same, especially where the swingarm and the engine mate up?
How much different are the 426 engines from the 450 engines as far as mounting points go?
Any help would be greatly appreciated.

I knoew that about the oil in the frame thing.
I have a 2001 now, Dubach racing sells a wet sump kit that I am thinking about using anyway.
Part of the reason for the 03 frame was to get rid of the oil lines on the bike for the most part as well as build another bike with the 05 plastics and the 01 engine.
I think the 03 frame is slightly lighter than the 01.
