Hello Mr Admin,
If i replace the camshaft with a costume made hyper camshaft, the result that you said surely adds torque and horsepower to the little Yamaha Fino. but, can i know the negative effect to the engine if i replace the camshaft? for your information,i already change the block size up to 58mm. im using my fino for normal ride, not for racing.

Replacing the original camshaft with an aftermarket "hyper" camshaft will have the effect that your motorcycle will become a bit thirstier. As your bike becomes snappier, some call it more nervous, as with even a little twist of the throttle will make the engine rev.
If you ride your Yamaha Fino on long stretches of road, you will find that with an aftermarket hyper camshaft it is more difficult to keep a constant speed on your motorcycle.
The quicker revving of the engine will also put somewhat more stress on other engine components. It is wish to use the best engine oil you can get, and better be early then late with changing the oil.
For the quality of the camshaft itself, we have seen some bad quality aftermarket camshafts, made from steel that is totally not suitable to make a camshaft.
