nope, eventhough from far looks like the same but they're actually different.
3-bold got that black plastic that cover the end can while triovale didn't.

hmmm.. from my experience, both have the same level of loudness.
but 3-bold is kinda unique because of its dual-sound feature.

any comments bout racing bee's power booster ??? can feel any difference??

We should keep our rpm below 4,000 when the engine is new rite??? (learn from the anime Wangan Midnight XD) guys is tat possible to install this rpm meter to our bike??? http://www.mudah.my/Jasma+rpm+meter+digital-6074636.htm

FZ block lor like wat ghost-lord suggested.... =) read last few pages... then u'll know...he did bring up something about fz block.. fz block is 57mm.. racing block is 60mm...

u want to race or what?? huhu ... if not it will not heat so fast ... take out ur thermostat ... good fuel setting ... by pass relay for radiator fan..use special engine oil ... it will help to reduce heat so much... but remember ..racing block won't last long.. but fz block original diasil block and u can think..huhuhu

Another way go for TDR block ba... I m veli confused about the break-in n the pantang like wat we always said... Break-in theory ask us to rev kau kau when the block is new, but for the pantang theory we hv to ride slow to prevent damaging the engine... Walao i cant understand la anyone can explain here???
