Universal 132cc Big Bore W/mikuni Vm26 & Os Valve Kit - 13-18 Crf110 - Tbw9139 [limited Qty] [S1DRT6U3]

132cc Big Bore Kit & Mikuni 26mm CARB with Oversize Valve Kit
 Fits: 2013-2018 Honda CRF110F
Part Number: TBW9139
 
TB Parts CRF110 132cc 55mm Bore Kit - This is as big as you can go without having to bore the cases. 
Includes:
- 55mm aluminum cylinder
- 55mm piston kit
- 55mm head gasket set
- VM26 carburetor
- Rear facing manifold kit
- Foam air filter
- Throttle cable
- Set of HD valve springs
- Intake valve 1.5 mm oversize and exhaust valve 0.5mm oversize
(valves are made from EV8 stainless, lighter than stock and profiled for better flow)
 
TB Parts is proud to offer a +1.5mm intake and +0.5mm exhaust valve kit for the 2013 Honda CRF110. Our oversized 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 oversized 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.
