I've already posted here once about this ATV. Lots of people suggested i check the cam and after a couple months i finally got around to attacking it. I got it all apart and got the cam/rockers out. I'm almost positive they need to be replaced, they're pretty scored up and don't look too hot. Just wanted some final opinions before i drop the money on it. I'll also take feedback on the new cam i've chosen.

Yep the lobes  look a little beat up to say the least.  I would change the rockers as well. 

I would also go with the oem cam if the engine is all stock.

Make to run oil with high zinc and phosphorous ZDDP, in the engines. Lots of oils these days have very low zinc and phosphorous content which causes cam wear in these engines.
