Bos KIRK 2014 User manual - Manual (Page 9)

What is the basic set up ?
Your shock has been set up for your bike, with a specific internal valving and a specific air chamber volume. It is
delivered with a standard pressure of 80 to 100psi. You can find in the download section of our website all the infos
about standard settings for each bike.
There is air leaking when I connect the high pressure pump, what can I do ?
Check your pump : make sure that the shell of the shrader valve is correctly mounted.
My shock is too stiff on the first inches of travel and / or the rebound is very fast . What can I do ?
The balance between the two air chambers is not correct. Refer to chapter 3.2 to check how to set it up.
Once reassembled, the stickers are not aligned. What can I do ?
To be sure that the stickers will be correctly aligned, the rebound knob must be perfectly aligned with the piggy back
when you start to screw the air chamber. Check it on chapter 3.5
My shock features negative stroke. Is that normal ?
The air spring of the KIRK is designed to obtain the best sensibility on the first inches of travel. Thus, on a few
bikes, you may notice some negative stroke.
Where can I purchase original stickers and valve cap ?
You can purchase these items through your approved BOS center, or on the Bos store on bosmtb.com.
I noticed some play between my shock and the frame, what can I do ?
The rear shock mounting hardwares must be replaced. Contact an approved BOS center, or connect on
bosmtb.com.
My shock is getting compressed when I deflate it, is that normal?
When you deflate your shock, you deflate only the positive air chamber. The negative air chamber is still
pressurized, it acts in the opposite way, and pulls the shaft. If you want to avoid it, deflate step by step (30 to 40psi),
and proceed to the balance of the air chambers between each step (5 to 6 slow extension moves, forth and back,
on 15mm).
