I just ordered my yz cam. Then for the fun headed up into the desert, there was a little bit of mud and snow but other than that conditions were xcellent!! The bike was fantastic, it ate those whoops and that sand alive. When I get this cam in can I expect any jetting changes. My elevation here is around 5000ft. Thanks for the help.

keep a close check on left side exhaust valve bucket. the yz decompresion pin eat my valve bucket up. the yz pin was longer than the wr stock. i installed the wr pin in the yz cam. i dont have any results back yet on wear. but i may have had a bad part from the start. our local dealer is sending a message to yamaha about this problem.
