Big Boy Spring Experience

some have the 6.3 some the 6.5 some say the stock spring is fine??
 
Is the C clip the rotating collar that sets the spring preload?

No. The C-clip position is not visible unless you remove the spring from the shock. Yamaha delivers them stock in position 1, which is the softest. There are 3 C-clip positions, and once you choose one of the three then you can use the 7 preload positions with the rotating collar to fine tune preload (AKA sag, AKA sit-in) within that C-clip position.

i have an attak and i put the heavier spring on.Alot of people say to just move the clip, but when you move the clip the spring has less travel for a full stroke.I put in the heavier spring in postion 1 and it rides great(im about 230-40 loaded)and has a full stroke.

i did the same thing for the same reason

06 Attak & Same here. Heavy Spring--- Clip 1--- Cam position 2. It will still bottom once in a while but overall it rides great. 280+ with riding gear.
 
I have an RTX and I added the big boy spring. I weigh 210 without gear.

When I compared the big boy to the stock spring, I noticed the coils were thicker but the spring was shorter than the stocker.

I decided to install the c-clip in number 2 position to make up for the shorter length.

The ocasional bottoming is gone, but when racing from a dead start, the rear suspension does not compress when you pin the throdle!

I am going to move the c-clip to the first position and see how it works.
 
Shorter and thicker is always stiffer than longer and thinner. Take two pieces of steel rod of different lengths. If they are the same thickness, one is 4" and one is 10", if you try to bend both of them, which will have more rigidity? The shorter one of course. These physics don't change when you coil them up in to a spring. I know, it seems backswards at first thought, but think about clutching. A shorter spring of the same diameter will have more force than a longer spring. The thickness part is obvious!
