I'm sure this has been asked a million times, but i seached it and didn't get any answers. So, will the exhaust cam from a 2003 wr426 fit in a 1999 wr400? It is wanted for the auto de-comp. If not, will a hot cams cam have the auto de-comp? Also if it will fit whats a good way to plug up the hole for the de-comp cable once it is removed? Thanks for any help.
