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 **Note:** This 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. **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 ## 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.
