    2005 crf250r carb question

    by Jud » Sat Nov 30, 2019 4:01 pm

    Hi everyone, first time post here.

    I have ridden Yamahas for a while but recently switched to a Honda. I am planning on doing a JD Jetting kit and the AP mod.

    The question I have is if I get the crfsonly new AP kit (the one that is 37 bucks and requires removing the check valve), will that work for a 2005 crf250r? I am familiar with the AP o ring mod on FCR carbs. Will I need to do that in addition to the AP kit, or does the kit just work as is?

    Thanks!

    Thanks JimDirt, I was referring to https://www.crfsonly.com/catalog/produc ... ts_id/3932

    Basically what I am looking for is the smaller piston for the AP pump referred to in the how to article for the AP pump mod. I would assume that the AP pump mod is valid for 250rs as it is referred to a bunch on thumper talk.

    Thanks for your reply!

    Yea that is just the pump kit , you still (as far as I know) need to do the AP Spring Mod with the O-Ring , that should get rid of any bog/hesitation , as long as you are jetted correctly for your elevation .....

    leardriver is the carb guru around here , and Ken (the owner) can tell you as well (which is why I gave the PM link to him) if you need more detailed info , they are the ones to ask ....especially leardriver , he knows his stuff about carbs and EFI
