Hi, I have a 1999 Wr 400 that is currently being rebuilt to the YZF-426 components. I've used the parts list from the forum and powroll. I'm still not sure on which crank assy to use. Would it be for the wr 400 or 426? Parts numbers are 5GS-11400-00-00 which is the wr400 or the 426 5JG-11400-20-00. Also I'm debating on doing both Hot Cams while it is in the shop. I'm sure everyone will say go for it. I plan on using it as a commuter bike and am looking into some street tires, alittle more street then the Dunlop D606. Also need a new chain and sprockets so I'm looking for recommendations for the sprockets to make it more street worthy. Any help would be appreciated as this is my first dirt bike and I'm not very mechanical yet.
