1. How to bleed brakes:

 

No big secret – no fancy tools – well maybe one but it’s a tool few people today seem to want to use – that’s the brain!!!!!!

 

  1. Everything has to be angled so no air can get trapped at a high spot!!!!!!!!! Use your head here – the master cylinder must be angled so the outlet hole is the low point!!!! The caliper must be angled so the bleeder is the high point!!!! Don’t want to take the time to figure this one out – don’t bother to read on.
  2. Now put a 8 foot length of 3/16 inch clear hose on the bleeder and open it 1 turn.
  3. Fill the master cylinder and keep it full!!!!!!! If you cant keep it full – don’t proceed!!!!!!
  4. Now suck on the hose till fluid comes half way up the hose.
  5. Close the bleeder.
  6. Pump the brakes a few times.
  7. Remove the hose.
  8. Open the bleeder and let the final bubbles push out with gravity DO NOT PUMP THE BRAKES WITH THE BLEEDER OPEN-------EVER.
  9. Pump the brakes again and repeat step 8.
  10. Now you are done – if the brakes are not bled – you missed something!!!!!!!

 

 

2. How to measure ride height.

There are 2 places you need to measure from the bottom of the frame to the ground (with rider standing on the pegs):

1)       Right at the foot pegs

2)       22 inches forward from foot pegs

To measure ride height - the rider must be standing on the foot pegs and the measurement needs to be taken from the bottom of the frame to the ground at the 2 points mentioned above.

3. How to measure race sag.

1.        Race sag is the amount the quad settles from fully extended with the rider on board.  First, put the quad up on a stand, measure the distance from the axle (vertically) to some point on the sub frame (make a mark if you need to).

2.        Take the quad off the stand, put the rider on board standing on the pegs, have the rider hold onto something for balance, bounce up and down a little to stabilize the rear end.  Now again measure the distance from the axle to the point on the sub frame where you took the measurement in #1.

3.        Now deduct the measurement from #2 from the measurement in #1.  This is your Race Sag.

4.        To adjust Race Sag tighten or loosen the preload adjusting collars.  If you have too much race sag, you need more preload, too little race sag you need less preload.
