How much pressure to pump up your front bags??

Hey all! Ive got a quick question.. Its aimed at B2200 owners!

I want to know how much pressure is needed to pump up the front of your B2200...

Reason:

Ive just got my airbag setup up and running...
I haven't got a guage on my tank to tell how much Pressure is in there..

If I let my compressors run for about 5-10 mins, then flick a switch to the rear bags, they fully inflate pretty Damn quick!
BUT if I try the front - they only pump up about HALF way! MAX!!! Thats it!! but while their at half way and won't pump up anymore, I can still get the rear to deflate and fully inflate a few more times! so theirs still plenty of air in the tanks...

When I look at the guages - it only shows about 40-60psi in the front bags!

I know that the front is a fair bit heavier (motor), but didn't think it would make THAT much of a difference...

So yeah, My question is - will your front fully inflate at 60psi?? or would it need heaps more??


Can someone tell me if at about 60-70 psi - if they hit all 4's - that their back fully inflates - but their front only half fills??

Thanks in advance!
