Australian Karting Forum

Hi All,

Hopefully there is somebody that can answer my questions on this forum as have tried using the new kartbook forum site but no responses as yet. 

I hear people at the track claiming there is up to 3 tenths difference between a good Iame x30 and a bad one (standard), but then there’s others saying they have very close parity between them. 

Is this true in your opinions, if so is there anything that can be changed in the engine to make a bad x30 better.

What sort of things can be altered on an x30 to make a engine faster?

Are after market parts allowed to be used in an x30 ie: Main bearings , seals ,pistons etc.

Does bore size make any difference.

Has anybody had evidence  of noticeable differences  on a Dyno or on a track to show this.

Looking forward to hear some comments on this topic.
