I was considering getting my brother the hot cams for his 02 426 for Christmas so he could eliminate the manual decompression lever for startup. He uses it for woods riding. But I was wondering what to get. Should I only get him the exhaust cam, or both the intake & exhaust cams? And do these cams hurt the bottom end power at all? He would actually like to gain bottom end power, I'm sure he wouldn't want to lose any down low.

Some input from someone who has the hotcams on their 426 would be greatly appreciated, thank you.

The '03 YZ450 exhaust cam works just fine. Gives a good power spread which is ideal for woods riding. Remember, for woods you don't won't more power, just a good spread of power.

That would have been my recommendation at one time, too, but since the price of the OEM cam has risen past that of Hot Cams', I think it better to use theirs. The current stage one is nearly identical to the 450 grind, and the timing marks are already set up for the 426, so you don't need any special instructions to install them.

So you would use only the hotcams exhaust cam?

I'm kinda leery about the 450f cam since somebody said the pitch on the teeth is different from those on the 426.

The pitch is the same. The profile is a little different, and the chain sits higher on the OEM 450 cam than it ideally should, but in the 6 years people have been using them in earlier bikes, it has never caused a single problem.

My only reason for recommending the Hot Cams unit over the OEM is price and simplicity, as stated above.

Get him a new cam chain while your at it. I just did the mod to my 99yz400 with the stage 1 hotcam last week and being cheap i didnt get a new chain.. went for the first real ride this weekend (camping at Busco Beach) the cam slipped forward one tooth the first day and i went in and fixed it then it did it again today and i put it on the trailer for the rest of the trip...

Which is better, the Pro-X cam chain or OEM? or other? I'm assuming the guides should be replaced as well?

OEM chain. The guides will not likely need replacement, but you should take a look.
