I do not agree with the "it makes jetting easier" thing about tors removal.. I did mine as I was under that belief, and convinced of the future possible issues.
I think it'd be just fine with em. If they give probs, then worry about it.
Jetting I think only gets easier if u remove the air box and run pods. I still run a box without lid mostly, and it's still a pain in the ass to change jets.. But honestly once u get jetting dead on, u change it for temp and elevation if severe enough change.
I put lid on air box in winter and don't change anything anymore. But, I guess if u are constantly pissing with jetting, then remove tors, and eliminate air box.. Other wise run it till u have issues..
