CRF's Only Forums

Hello,

I’ve been lurking a while.

I have a 2014 crf 250L. There is an Allen bolt on the bottom of the crankcase and I’ve been wondering what it’s for. It’s not the oil drain bolt.

It’s #2 on the parts diagram. Part #11107-kyj-900

Just curious. Thanks for the wealth of knowledge on here.

Welcome to the site !!

I searched thru the Service Manual , and I can not find any mention of it , it shows it , but does not give a reason or need to unscrew it ... so not sure what its purpose is either Maybe just a secondary drain plug , it looks the exact same as the actual drain plug on my 2020 , and it looks to be in the sump area , so maybe it is just that ... a alternative oil drain ... however , I would not use it unless you have issues with the regular drain bolt , as it does not give a torque spec for it , so I would guess they do not want you messing with it ... Sorry ...

Only other suggestion I can think of is to contact your dealer and ask them if they have any idea what its function is ...

Thanks!

Ya I’m not going to mess with it was just curious. I’ll see if the dealership mechanic knows anything. I try and stay away from that place. Have a habit of walking out with stuff I didn’t know I needed every time I go.

Yea ... I hear ya ... that is why I shop online ... , I don't have as much guilt if I have to wait a few days for stuff , then it feel like I am getting a gift , I have spent about $2500 on stuff I "really needed" in the last month or so .... but my bike and my truck personally thanked me for it ... so there's that ... ...Well actually I spent a lot more than that , but that is what I did not finance ..... I also got wheels and tires , and a lift kit for my truck , and a few other things for my bike , like suspension springs f/r , and a few other items , I "really needed"

Yea , maybe they were trying to transition the oil drain to the style my bike has .... that way it is 1 drain plug for all models ... who knows ... , I am sure there is some kind of purpose for it , but nothing in the Service Manual says anything about it ... so maybe it is just how like on the 17 450R they made accommodations for a E-Start , but it was a "option" , then in 18 they made it standard but kept the kick start , then in 19 they removed the kick start but kept the option for it , then in 20 they removed the option for the kick and made it only button .... so maybe it is a transition part ... in that sense ..
