Transworld Motocross just tested the lastest beast I created. Fast Core Mods did the head Work, Millennium the big bore cylinder and CP the high compression piston,

Stock is 76.8mm and big bore is out to 79mm making it 264cc and the results are great! Big power gains for low cost in the new CRF250R with no fuel mapping changes.

The Honda 400 motor is proven but can just use a bit of a boost from a cam and piston. Hot Cams and CP took care of that with a FMF pipe.

Custom CP Piston matched up to a Thumper Advanced Sleeve. Travis at Thumper got this running really good and way more power than stock.

FMF Polaris 450 project with Fox Shox — came out great. Cain was very impressed with the mucho power.
