if you've never worked on one i would have someone there who has to watch over you! it would be a great learning experience, and yes you will more than likely have to reshim with a different cam. and use the cams specs not stock!
it is relatively easy. read the pinned how to and youll be set. make sure you have all the tools u need. if you get stuck or lost on something post up a question and we'll help you out.

if you have not had you valves adjusted most likely youll have to adjust them at this time. the cam does not affect the shimming. its a good idea to buy a shim kit. once you install your cam youll see how easy it is to reshim your own valves, and youll save alot of money vs having the dealer do it.
lol...ok heres my scenario...my valves bottomed out...ruined my head..

so i bought a new head that was in great shape and along with the head i bought a sparks mx cam,
which since it is a mx cam i was expectin to be nuthin but tourque...but i took it to my mechanic and he calls me up and say...everything is together and workin great...but i took that cam you brought me back out...it was lackin bottom end really bad, he told me he would put it back in if i wanted him to....but the guy is about 2 hours away and my 450 has been down for 4-5 months and im to anxious to ride to wait any longer..

so im just gonna go pick it up and put the cam in myself...he already adjusted the valves and all that stuff.
even easier.

still read the "how to " thats posted in the maintenance section.
that way youll know what tools you need and the process of it too.
no bottom end???????

watch out, sounds like your mechanic is a little kookoo

anyways I hope you get it worke out..

thats what i was thinking. its a fourstroke it don't matter what cam you have in there it will have plenty of bottom end.
Yeah, Its hard to find a good trustworthy mechanic in my area without going to a dealer and it costs an arm and leg there to get anything done, I think my best option is just to start workin on it myself.

yup, just take your time on it and you can definately do it on your own. look at the rockinhorse website, there instructions are very usefull.

If your cam is out, you better make sure your shims are still in place. They will not stay in place by themselves if your shipping the thing around.
Somewhere on Ebay I saw someone selling a video on it. Mayby that would be a good purchase for someone who wants to do it but is not sure.
Just changed mine, and used the directions on the website, I had it donr in about an hour or so
