    Got the standard 17.5mm, was thinking about upgrading but not sure what difference it'll make

    You'll see a great difference from a 17.5 to a 21mm. Would definitely recommend that as a next step. :good:

    adding a crank and doing the cases at the same time would give you a serious hike in power wihtout really loosing any power. common practice in europe/among tuners is to fit a crank and flow the cases when fitting ANY cylinder kit
