Xb4 setup worksop indoors
 

Can any helpful soul offer a setup for the XB4 and XB2 please?
I have a rough idea of where I'm at but wondering what differences or improvements I can make.
Xb4 is a '15 spec run in shorty setup.
Xb2 was a CE, started off running DE gearbox now switched back to CE setup for more on power steering.
I have Avid 2+2 pistons for both cars now.
Any tips much appreciated.
