TB Parts - TBW9139 - 132CC 55MM BIG BORE WITH BIG VALVE KIT AND CARB KIT - CRF110

CRF110 132cc 55mm Big Bore with Big Valve Kit and Carb Kit

This kit requires custom machining that should be performed only by a professional.

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 2013 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. 

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.
