look bulky! and additional weight! ano kaya advantage ng user?
the advantage of this is
-bigger valves by default = 26mm in / 24mm ex
-can accomodate bigger piston (more water jacket space for liquid)
-for the for the dual camshaft, i dont think it has an advantage especially if the cams used is stock cams. (advantage maybe if you can find a fully tuned racing cam)

papa job how tong logis ko sa small displacement engine applicable din sa big

more moving part more friction...more friction more lose of power... so somehow for a smaller engine mas ok ang SOHC...tama ba? so more effecient ang stock settings!

It's the reason that piston 63.5 with CBR is 150cc while work with T135 it up to 180cc
question bro! the Top Dead Center for the piston of this engine with T135 connecting rod is lower than the one with CBR 150.. am i right?
