Fella's,

Are these two parts interchangeable?

Seem to remember reading about some woodruff failures on 03 models, did anything change on the 04?

Buddy in Thailand needs new conrod/bearings but likely cheaper to get a crank.

03 and 04 have different flywheel tapers and diameters. You can use one or the other but you have to have the matching flywheel to go with it.

No problem. I went through this same decision when I rebuilt my '03. I decided to stick with the '03 crank since I already had the flywheel. The keyway problem was resolved with the '04 starter drive upgrade which I highly recommend doing. Once the upgrade is done you will not have a problem with either crank.
