● CNC X250RR 8.6 CAMSHAFT & LARGE DIAMETER ROLLER ROCKER SET
● The YUMINASHI Billet CNC X250 8.6 Camshaft Kit is the hot ticket for getting the most out of your Honda 125 or 150 engine.
Yuminashi camshafts are designed in conjunction with our racing efforts, and in turn the design gets passed down to our customers for the best power gains.
Yuminashi R&D designed this camshaft to be used in combination with the stock 125cc, 150cc or Yuminashi 31mm valves, with a increased lift and duration to produce a potent curve with solid torque to red-line.
● The stock 12.95mm roller diameter is adequate for all stock camshafts, but high performance engines with high lift camshafts benefit from larger diameter rollers for the simple reason that the larger face of the 16.9mm rollers accept a more aggressive lobe profile before the roller digs into the cam lobe, which of course leads to nearly instant camshaft failure.
Therefor the rocker set with larger, more durable rollers comes together with the camshaft as a complete set to ensure increased durability and reliability.
■ We strongly recommend to install these larger roller rockers, camshaft damage will be the direct result if you install the camshaft with the stock 125 or 150 roller rockers.
■ The optimal valve clearance with this camshaft is 0.05mm IN / 0.08mm EX, make sure the valve pockets in your piston are prepared for this clearance if you are using a non Yuminashi piston.
■ Installing a high performance camshaft with more lift and duration might affect the operation of the Idle Stop Start system (if such a ISS system is installed on your bike).
