re
jaks-i don't know for sure what comes in that kit but i don't think you needed it with just
pipes-the 800 runs fine on stock carb with aftermarket pipes so i'm confused about that.
but generally the most common setup on the 800 after a pipe change is either
hypercharger or thunder air kit-some folks have had issues with the hypercharger
sticking out a little far and rubbing their leg,but there is a mod to rememdy that.
others like the thunder kit claiming that it breaths a little better but no real advantage over
h-charger other than looks.
most folks are running a 48 or 50 pilot (48 is stock) and 165 main(135 is stock)
with 2-1/2 to 2-3/4 turns out on the air/fuel screw from seated position
some are using shims some don't but that combo seems to deliver the bang for the buck
look at those thunder air kits if your have'nt they are nice looking with different covers
they have for the filter
some people have complained about the butterflys sticking on the h-charger also
but i don't think thats really and issue.
good luck and keep us posted :wink:
