31k motor in 4L0 frame front sprocket alignment

[soccersmyth]

I will be fitting a 31k motor into a 4L0 frame witha RGV banana arm and wheel.

I have been told that the front sprocket offset to align straight to the rear sprocket is not the same on the 31k and 4L0 motor.

What do i need to do to get it aligned ?

The first bit of advice,is to make sure of wheel allignment
You cant rely on the chain pull markings on the swinger alone
Use trammels or a laser pointer to determine front to rear wheel allignment,, if you are using track-scrub tyres make sure you do multiple checks on various points about the wheel
once satisfied..have a look at the chain pull markings for general reference...
Ok then back to the initial ask...check final drive allignment
