Hey guys, Helping a friend with a 2006 YZ450F that is set up for flat track and trying to figure out what cams are in it. He had someone do some work on the engine a number of years ago and they installed aftermarket cams. The exhaust cam has spun the gear on the shaft and needs to be replaced. He doesn't have any boxes, documents, etc that were given to him that identify the cams so I was hoping someone could tell me who they are made by. The intake cam has the following written on it - WW-HCHE NO:23 And the exhaust has - HCEH NO:22 on it. I've tried looking on different manufacturer's web sites with no luck yet - can't find a match for them. Thanks in advance!
