Hot cam or R cam

Posted a while back on modding my 2013 crf250x and have started thinking about changing out the cam.

Have found the hot cams stage 1 but I have read that you can change your stock cam for a r cam, which would do me better and is there any difference between the X and r hot cams or are they universal

I would go with the R cam.
Hot Cams have questionable durability. If you go after market, Webb is a good choice.

Is there a website (no pun intended) for Webb cams? Couldn't find anything on them

Edit. Found them Web Cams. Little to much for me don't plan on doing all my valves and springs too. I've read that 05 R cam fits and so does the 08 but which one is better I can order them and not have to change any oem parts because my bike is basically brand new and they will wear evenly.

I've also read lots on the CCC mods but it only really talks about 04-09. I want to do some of the more simple mods but can't find any sure info and not really much info on my bike at all

IMHO you should sell this bike and buy an R or a ktm300. In the long run it will be cheaper and more reliable to get the power gains you are looking for.

Got a killer deal on the bike in the first place, and my goal with this bike isn't to make it an r I love all the enduro stuff, but I want to be able to do everything without being left behind. And it's more fun building a bike costum to what I want, I'm a heavy duty Mechanic I like getting my hands dirty.

But in a few years when I can handle every ounce of power outta this bike and it's not enough I'll hand this down and buy a bigger bike and do this all over again and hopefully better

It's not that you have a bad platform to work with but the amount of money you are willing to put into it. You'll dump 4k into trying to get every ounce of power out of it. I understand changing out the cam for a torquier throttle response (which you should change out the valves, springs and keepers by the way) and I get tuning the exhaust for better power in different stages.
You won't get that fast as shit motor though without dumping tons of squish into a 250f motor period then you're still gonna be mad and looking for more power when a 450 or 300 passes you.
An old MX guy once told me "it's cheaper to go slow on a fast bike than it is make a slow bike faster."

Both cams will work for you,it depends on what your looking for in your bike,a R or hot cam will help with mid range to top end power gains. A properly jetted 250x will make significant performance gains also.

I bought the emissions block of kit already, comes in, in a couple of days.

Don't know if you ment 250x or 250f I never said my bike was slow, I'm a beginner rider and haven't even developed the skill to use all the power outta my bike and when I'm done I'll upgrade but I feel a custom bike is more fun than a stock bike just on the hours of work I've out into.

And I've ordered in a full jetting kit, if I'm gunna do something me personally I'm gunna do it right. And plus when you pay for upgrades in not only performance it's also a look.

I just spent 7 grand on a brand new showroom bike I'm not gunna sell it to get something I coulda got the day I bought my first bike.

the emissions block off kit will only stop any popping noises from the muffler,it will not affect performance at all.
the crf250x is a sweet bike,handles real nice,and is more than enough of a bike for a beginner rider,enjoy it.

I would consider leaving the aixbox alone imo, cutting it just makes the air filter get dirtier quicker,also if you do any high water crossings .

I have heard that the emissions will just help the bike run way better, and doing all these little things will eventually add up removing the lag outta 3rd I get. I'm gunna do it right, and I don't do much riding threw water lots of sands and pits I like to mess around

I went the other way with an earlier crf250. you may like a different adjustment or pump setup on yours if the bog is coming when you open the throttle more quickly. Web (webcams.com) makes a cam grind that works with the stock springs if you ask for. It was developed for Honda Racing and was an early supercross profile. I use the 2008 cam, but I am going to get the Webb and get it with an adjustable sprocket. Bigger is better when it comes to making the lag between the wide ratio gears easier to take. my next trick is to machine a set of cases I have to accept the the crankshaft out of a 2011 to go with my bigbore cylinder. The cam chain from the newer bike should let me lift my cylinder, keep the longer rod and be happy. I have two of the wide ratio gear sets, a set of CRFX cases, but havent put an ebutton on mine yet. I considered using a cam like you have by the way, looking for a more slow trail oriented bike. with the bigbore kit and the light flywheel of the crf the bike is a bit twitchy in low gear now. I havent tried it with the crf primary gears but that is on the list when the longer throw crank goes in this winter.
