White Bros E series

[Quaddog3]

Just got myself a 400EX and it has a WB E series on. Trouble is I have no spec info or tech details for adjusting. WB site also offers no info.
Can anyone help ??
Apparently no jetting changes needed but how do you adjust for noise / performance

Many thanks

Removing discs reduces noise and boosts low end performance.

Adding dics, more noise, better mid-top performance.

If your quad has an aftermarket filter and/or removed/modded airbox lid, I highly recommend re-jetting your quad.

No mods to air box or filter yet, But I defo understand the re-jetting requirements..... I used to have a Banshee and that requires jetting if you break wind..:rolleyes:

To remove the discs, just take out the 5 hex bolts holding it on at the rear of the pipe. Pretty easily done.
