Seriously thinkin of getting the ehs big 3 set up along with maybe a 13t sprocket. I am curious on a couple things. I've been reading ALOT on here an.. does anyone run the big three in really cold temps? I ride snowmobile trails in the winter most of our rides are anywhere from 30 to 80 miles. We just did a ride a couple weeks ago where we did 70 miles an it was only 11 degrees out. Does anyone run the big 3 in these kind of extreme temps? Really worried about it leaning out on me. Also, am worried about sound, I know the barkers has a quiet core but.. how does it sound? I had an FMF q4 on my old honda 4stroke dirtbike an liked the sound nice an quiet. My buddy has the full muzzy on his kfx an it sounds AWESOME! Thanks for any input!
