    250x + 250r

    by dilledpickel450 » Sun Apr 10, 2016 9:56 am

    I am looking to pick up an 07 crf250x, needs a head, will an R head fit if so what year? Will an r model head pipe also need to be used? (not sure if exhaust port is the same diameter). - Thanks!

    The '04-09 250R heads are bolt-on compatible with th3 250X with the exception of the R heads do not have the emissions port. So, if you need this you have no choice but to stick with the 250X head. The X header will work with the R heads mentioned here.

    Thank you for the input. It is a CA model so I am guessing that it has the emissions. Pick your brain one more time, what cam can I run in it? I was reading that Hotcams are good but mostly for bottom end to midrange. Will an R model stock cam work?

    All X models for all states come with emissions now and have for years. Some don't need it for close-course riding/racing so they remove it to save weight with a block off kit. If you have already done so then the R head will work. We have them with our CNC work and Kibblewhite Stainless Valves. Great set up.

    Hot Cams makes Stage 1 (low-mid range cam), Stage 2 (like the R cam with a bit more power). R cams of the same years will work ('04-09). The '08-09 cam is generally accepted as the best of the lot for use with the X. With our '07 KW R head, the '08 R cam or the Stage 2 Hot Cams cam and a higher compression piston with the pink wire mod you'll get more power everywhere and will be very happy with the results.
