just wanted to no what would give my bike more power, irk or ork?

this has been covered a sht load of times in the past...

the lifan ORK hands down, provides easier starting once setup properly and has the correct advance curve in it unlike the IRK.
also the ORK wont rob all the torque out of your engine and wont stall easy like the IRK
