B&B Cycle Restoration 305cc Big Bore Kit for the Honda CRF250L.
There's no replacement for displacement and this kit proves this point for the CRF250L. The stock CRF250L produces approximately 17hp. This 305cc big bore kit will kick your CRF250L to 24hp!* We highly recommend the optional EJK fuel module for maximum increase in power and throttle response.
NOTE: No core return is required. However, B&B will buy your original cylinder for $75.
Big Bore Kit Includes:
- Big bore cylinder
- Big bore piston kit
REQUIRED: The 305cc version of the EJK is required to safely run this big bore kit. Attempting to run it with stock EFI or even the EJK intended for the stock displacement will result in engine damage.
NOTE: * 24hp output achieved with 305cc big bore kit and the EJK fuel control module designed and programmed specifically for this big bore kit. This not the standard EJK control module. If you have the standard EJK controller, EJK will reprogram it for free. All you pay is shipping. CRF250L'13 - 305cc Big Bore Kit.
