PismoGuy400 the gliders are made for 4-stroke models as quoted by Rocky Mountain ATV on page 89 of their catalog. You may think it's hilarious but I also weigh 220 lbs. and 8 paddle tires is too much. I've tried both set ups and the gliders work best on a near stock machine like mine.

 

Pismo...I've actually raced and beat 250R's..Suzuki and Honda, running 6 paddle Gliders on my EX. I do just as good using those than my 8 paddle Haulers. Doesn't seem logical but it's true.

 

ok...your waight probably would bog the machine w/ the 8 paddles
it still seems wierd to me, but if it works for you im not gonna say its wrong

 

i have nothing to add to this topic but i was bored lol however 8 paddles is asking a bet much from a 90% stock 400ex with your pipe that put's you up to about 34hp

 

22" paddles are to much for 400ex unless bored.
