On the 2S legend... It might as well be a JS1. There weren't any JS1 cams when I put it in there. Not bragging about it. It just is.
My bike only feels like it pulls away from my hands a tiny bit when I get too comfortable daydreaming and whack the throttle in 2nd. I forget that it actually can move forward in a hurry with more than mild throttle input. It's no big deal, just a little 750, but it definitely doesn't go flat above 5500RPM. What it won't do that a stock motor might do is pull hard going up a hill in 3rd if I've already started up the incline at 25mph. I've tried it a few times, mostly by mistake. I either have to downshift into 2nd, where I should have been in the first place, or ease my way into the throttle forever.
Is climbing a hill in 3rd from 25mph on the incline an easy task for a stock 850? I am not knowing..
