Has anyone installed a big bore kit on their 2011 CRF250R? If so how is it working out?

What have they done to their bikes. Just the big bore kit or more. I have the hot cams stage 2 and some head porting with the JD jetting programmer. I asked someone at JD jetting about the big bore kit and he said he did not know if the JD jetting programmer would give the big bore enough fuel. This is my biggest consern and if I would have tech help getting it running right.

some have had us remap their ECM, others just the big bore kit. a remap is a must in my opinion as these are lean for most as it is.
