Hi all,

My MC28SE has been booked in for a dyno run on Wednesday. Currently it just has a set of JHA pipes but is otherwise standard. I have also purchased a MC21 flywheel which I am planning to put on and doing a second run to see how much diference it makes - anyone else done this mod or should I have just gone for the HRC card? I am also considering opening the air box up a little, will this have much effect? Will it throw the jetting far out as I have heard of a few people that even after lots of mods they still run pretty much standard jetting.
