Your dad is right, partially. The reason racing plug easy spoil because it's designed to be colder, so they tend to foul easily. Fouling means cannot burn off the petrol that stick to it... then deposit carbon... then shorted the plug, or cause wetness and spark cannot happen. Need to check compatible plug... check NGK website lo. If not, ask Megafortune for warranty...

oh, imagine if u going for a bump, just release the throttle and it will have some sort of clamping effect? ( sorta like engine breaking? )
meaning no nid to press break ( for normal average speed ) ?
or.. do we nid to press the clutch with the break simultaneously?
im sorry if im asking this but i really want to know about it before making my purchase =)
thanks to anyone who willingly spend time to answer my question (thx alexei! ) XD
No prob. For clutch and no-clutch... since i lazy to type, let's call them CC and NC. OK?

Between CC and NC, engine braking effect is the same. Only slipper clutch doesn't have engine braking, and this is found on supersports like the new Yamaha R1.
You don't need to press clutch when slowing down or cross bump, but need to press when stopping. If not, engine will off because of stalling.
NC clutch will release automatically based on the autoclutch principle.
Do you drive a car? You like auto or manual? Maybe this will help.
