This is how to adjust you vlocity:
This is with the stock fuison
Ok first thing you need to do
before airing you gun up is to set the regs.
There are two regs on the fusion.
1) HPR/OPR (as in manual)
2) LPR
I'm not going to get in how they effect the fusion and how the lpr converts the air and all that.
So here we go...
You need to bottom out both of your regs before airing the fusion up.
How do you do this?
Hold your fusion upside down so you can see the serial number (under the trigger guard) you will first set the HPR/OPR to 0 psi.
You do this by turning you adjustment screw clockwise so the adjustment screw is screwed in the whole way. Make sure you dont overtighten it just until you feel a little resistance and that should be good.
Now to make sure you have done this correctly look in the adjustment screw and make sure the adjustment screw is below the c clip. THis means that you have succesfully bottomed out the reg
Now for the LPR...
This reg is the reg that adjusts the fps on the fusion.
The LPR is located under the breech.
You once again turn the adjustment screw in, this is just like the hpr. As stated above turn it clockwise or in so its all the way in.
Now for setting your fusion up:
Now that you have bottomed out both regs now is the time to air up your gun.
Air up... pppppppppppssssssssssssshhhhhhhhhhhhh
your gauge above the hpr should read zero if it reads 600 its not my fault you are a newb and dont follow my directions.
anyways...
you should set your HPR to 230-250.
To do this you are going to want to turn your adjustment screw out or counter clockwise. You have to whatch your gauge do not let it go over 300psi. stop turning the adjustment screw out when the needle hits the line after 200 psi (this would be 250 psi the recomended pressure you should have your fusion at)
You have now set your HPR/OPR
Now for the LPR...
The gun should not cycle at this point (this would be a good time to turn your gun on

)
Now make sure there is
NO paint in your breech. turn your adjustment screw out or counter clockwise until the fusion fully cycles
Now head off to the chrono...
Keep on turning your adjutstment screw out until you reach your desired FPS.
All this for adjusting your fusion
THIS IS NOT AS HARD AS IT SOUNDS
*** your fusion will leak when setting the HPR and LPR this is just because there is not enough pressure in your gun to have the noid seal so just keep on turning up the presure to 250 not above***
If it leaks over 250 psi and your LPR is still bottomed out turn it up and it should stop after a turn or two. If it dosn't youve got a problem. I'll get up a leak guid when i feel like it.
I am not responsiable for any damage to your fusion
