Can anyone recommend what assortment I should purchase for as far as I know a stock WR400? I was going to do the yz timing and thought I should go ahead and get some shims and an assortment of jets. Would I be better off buying a JD kit and calling it good? I would like to have an idea of what sizes to get so I have a good range to fine tune. As far as I know the bike is stock with the WB e series pipe. I have tried to find info on how exactly to do "de octopus" my carb and where exactly the "gray" wire is also. Any help on getting my bike to the next level would be appreciated.
