Those are both 4mm motors, a stock stroke isnt going to make the torque a stroker does. Personally I prefer CPI's for a dune ported stock stroke motor.370banshee said:i ahve shearers on my stroker banshee.. and this thing make power everywhere.... also....... odaens dynos with his ported421 cub had sheares and he still made soem impressive low end considering the engine he is running... i say go with the shearers.... oh and rockets well....... i wouldn't even bother.... there is a dyno floating around of an engien EXACTLY liek mine (in fact i bought the cylinders from the guy and built the exact engine) it shows a 8 gain by ditching the rockets and going with a shearer...

Yeah, and the shearers are even worse on a non ported bike. They are both made for much larger port durations and flow potential than stock so niether are going to work worth a shit on stock setups.fast350 said:cpi's are junk unless the bike is ported, and have zero bottom end and torque.
Looks like the dick head right here.wesw said:you might have to ask nick i dont know much about anything.
