mods after break in?

Just wondering did everyone wait till after the break in period to change out the exhaust and add a programmer. Just got my bike last week have a 150 kms on it so far but the complete fmf package showed up today. Would like to put it on but should probably wait till after its broke in any thought on this? Thanks Steve

I did all the popular mods, air box mod, AIS removal, etc around 300 miles and my FMF muffler and fuel controller around 600.

IMHO, if you tune it right, not to lean, or too rich you should have no trouble. the engines are strong little beasts.

I would wait just so you get used to the stock bike and then you'll see more of a difference when the mods go on.

I waited, but that's because I bought my bike used, so the break-in period was already done.

Yea will wait the weather is still a little chilly here so hard to get the miles on. But really excited to open it up and gear it down.
