My name is Daniel. I just bought an 800ex about a week ago and have wasted no time modding it. I was wanting to upgrade my tires to a set of 28" bighorns and run the same size wheel/tire combo all the way around so i can rotate them. Ive got my eye on a set of ITP hurricanes wrapped in maxxis bighorns. 14x7 wheels with 5x2 spacing. Just curious what fitment issues i may run into?

None , enjoy.

What about clutching? I have read on changing to the B2 setting and changing to 24 gram slidders. Would i be fine with just reclocking to B2 and not changing nothing else?

yes

Sure. That will be fine. You can always do the sliders later if you feel the need.

Thats what i thought. Ive been reading on here for the past couple of nights at work. Bout to pull the trigger on some wheels and tires. I can sale the others as factory take-offs before they get scent up. Ive only got 30 miles on them here playin in the field. I'll post pics when I get it all my mods and upgrades done.
