hi all,
is it worth getting an irk for my stomp z140 ?
what difference would it make and which one is best ?
and has anybody got one of these and are they recommended ?

Is it for sm or off road ? If its for sm them yes more power the better

if its for off road then its down to the person riding. they do become a little snappy on a 140 and like to try and stall when coming in to corners because the revs drop quick but then you might get used to it

I have new irks fully tested to 15000rpm.
Will give you more power and quicker RPM.
