sound in rear drive

[Nlmman47]

I changed the oil in the rear drive. I notice as I spin the rear wheel. I will hear about every 2 or rotation. Have any ideal?
Question 2
I changed rear brakes and front brakes, I have good front but rear breaks I have to push the pedal down almost all the way. You think air or something that needs to be adjusted?
Question 3
Rear shocks is there a way to change oil or do I have to take it out.
Question 4
My bike has ran back when turn off about twice?
Any help

1. ???
2. Flush and bleed the brakes per the service manual. You will need to bleed the front linked caliper as well as the rear.
3. Your first stop should be the DIY articles here. viewtopic.php?f=14&t=18481
4. ??? Do you have to chase it?

Let me clarify
question 1
It makes almost a scrapping sound briefly about every two turns
Question 4
When I turn off it will back fire some and the engine will roll back, if you know what I mean

As far as the rear brakes, if routine bleeding doesn't fix it (you need to do that no matter what) look at the rear rotor and see if it is worn a lot. They usually wear more in the center and less at the edges and a new set of pads are flat and only touch at the less worn areas at the outer edges of the rotor which gives a lot less braking ability until the pads wear down to fit the curve ot the rotor.

You can't do anything about the oil in the shocks other than replace them.

Make sure that the idle speed isn't too high, that will make the engine diesel or run on after shut off.
