The bolt-on big bore kit provides more torque and pulls more air through the larger valves and performance carburetor provided. **Key Features:** - VM26 Mikuni provides crisper throttle response and consistent, reliable operation - Lightweight, larger valves for more efficient performance - All aluminum cylinder helps to dissipate heat better then stock cylinder - Big Valve Kit: +1.5mm intake and +0.5mm exhaust valve kit for the Honda CRF110. Our over sized valves are constructed out of EV8 stainless steel to provide superior strength and longevity over the factory valves. They are also lighter than the factory valves. Additionally, the valve profiles have been changed to yield better flow characteristics resulting in better performance. With these over sized valves you get the best of everything as the stainless material will long out live the stock valves, the bigger size will yield more flow thus yielding more power, and the lighter design will help prevent valve float give providing the potential to rev higher and faster and it frees up horsepower used to open and shut the heavier stock valves. **Recommended:** - Sta-bil fuel stabilizer - W-57-1129 **Application:** - CRF110 - 2013-2018 **Kit Includes:** - TBW0891 - Cylinder - TBW0892 - Piston - TBW0893 - Gasket kit - TBW0301 - Throttle cable - TBW0399 - VM 26 Carb - TBW0477 - Air filter - TBW0864 - Reverse intake kit - TBW0888 - Big valve kit **Note 1:** The stock CRF110 throttle is restrictive and will need to be replaced with a generic Honda type throttle. Option for the throttle below for a good solution! **Note 2:** The valve kit should be installed by a professional mechanic or shop that offers valve job service as the valve seats must be cut to accept the larger valve head diameters and valves sunk deeper to allow for overlap clearances. The kit includes a document that includes protrusion and installs heights specs. **Note 3:** When using TBparts 132cc piston TBW0892 you must use the supplied thick 1.5mm base gasket **UNLESS TBW0888 Big Valve Kit is installed**. It helps reduce compression to avoid engine knock. ## Shipping and returns - Flat rate shipping is $8 for parts orders under $75 and free for most parts orders over $75, within the continental 48 states.
