2011 250f big bore?

Hopefully I am not reposting here, but has anyone installed a big bore on the 2011 KX250F?

I run the 40+ class and don't want another 450. I really love the 250 but would like a little more bottom end grunt. I'm aware that I will probably lose a little over rev, but I'm not really up there much any way!

Thanks in advance,


I HAVENT heard of any on the 11 fuel injected yet, but i did one on a 09 for a friend. with stage 1 cams it was a cylinder works 270 kit, the cam dictated where the power was not so much the bore. 270 is perfect for not changing it that much. his bike with the cams and fmf pipe has a lot of touque of the bottom the front lifts easy with no wheel spin, kind of feels like a heavier fly wheel. hot cams has a new stage2 cam for the 11, that would be nice with the 270 kit. plus i like yosh pipes they work good. that would be a nice set up.

      2015 Kawasaki KX250f - 20 hours
      As close to new as I'd imagine you'd get! I bought the bike brand new, I'm older and have taken extremely good care of this bike. Very little use and is COMPLETELY stock - everything is original. 
      Comes with the title, original book and map couplers for the fuel injection.
      $4700 - cash

      Just thought maybe everyone could post up there youtube channels an we could all help eachother out by subscribing to one another.
      Heres mine ill sub back asap.
      This has been fun in other sections of TT, so I'll start the thread here and see if we can keep it going.
      Let us know what kind of mods, fixes, changes, etc.., you performed today, or just general fun you had with, your KX250F.
      I'll start with.. I installed a correct for my weight Race Tech shock spring, along with a Pivot Works shock spring thrust bearing. Also cleaned out all the nasty yellow plastic/wax crap that passes for grease in the lower shock bearing, and re-lubed it with Bel Ray waterproof.

      Time for a top end on my bike, just wondering if there are any alternative Valve springs i can use. I have PC cams and $400 for just the springs and retainers is alil costly at the moment.
