The infamous plug cap or should I just say it’s the famous issue? Anyway, my Hyosung’s plug cap has been cracked and I’ve just clocked 4128 KM! Yesterday, my bike was jerking if I ride below 4K RPM and this was very annoying as Naza claims this issue has been fixed on the newly 2014 bike.
The new plug cap which is still the same brand called Golden is said to better insulated plug cap (from 20% to 30% Rubber), increased temperature (250 to 270 Celsius) compare to the previous version.
First I thought my plug cap could be an older version, I went to NAZA SC in Shah Alam today and the guys confirmed it is the newer version! Anyway, they kept my cracked plug cap and they might send it over as a sample to S&T Motors in Korea for further analysis.
I forgot to capture the image of the cracked plug cap as I were busy chatting with other riders! 😛
As the picture below, the only changes I’ve made to this bike is installing new TBR Silver Series muffler (Original). Could this be the issue of the plug cap cracked? TBR Muffler is widely installed on Hyosung bike (Special Edition or TBR Series) in Malaysia by NAZA.
For backup, I purchased another 2 plug caps, RM 35 each just incase it cracked or break down again.
So what are the symptoms?
-Bike will be jerking if you ride below 4K RPM
-Unstable RPM when the bike is Idle
-Unstable sound or noise from the exhaust pipe.
How do you differentiate the newly improved plug cap with the older one?
It’s easy! The newer version has a shining material finishing, just like a gold dust on it.
Looks like Naza have to request much more higher qualities Plug cap for Malaysian blade owners especially due to our country’s temperature?
To be honest, I heard some riders are using Suzuki’s plug cap which is said to be better than the stock ones. If this plug cap issue happens again, I might try Suzuki’s one.
Finger crossed that it will be fine as I’m planning to go Thailand on June for Sadao’s border bike week.
