BRush, How did the EG 225 work translate to how the bike feels on the track or in the woods? Like throttle response, power to the ground, top speed, etc..
Much more luggable that the 200, but without the “flattening out” on the top end that you typically get with the (stock) 220. Not hugely different on top than the 200 w/ an FMF pipe, but then I don’t jet for top end. MUCH stronger in the midrange. In August I lent my KDX for the Red Fox Turkey Run to a friend after his bike (KTM) was mechanically DOA. His comment after was along the lines of “What did you do to this thing? I don’t remember my old KDX pulling wheelies like this!” Eric offers three different porting schemes, basically low, mid, and top and porting is included in the bigbore kit, along with PV disassembly and cleaning. It’s one of the best deals going.
Throttle response from the big bore kit is hard to quantify, because I did the RB carb mod at the same time and I chalk up the big improvement off-idle response to that.

And do you have to do top ends on a more frequent basis?
No. After doing one per year and seeing no significant wear, I let it go two seasons and will do one this winter. If you are going to send your head off to Eric, don’t wait until spring because he gets swamped from about Feb to May.
