When you say 'blank off'....
You can disable it using the switchgear on the LHS on the bars.
Or do you want to remove the hardware?
Presumably,you want to disable it completely.
You will need a new set of brake lines(available from hel etc.) front from master cylinder to calipers and rear master cylinder to caliper.
You will then need a link pipe to go on the abs pump and need to blank off the other two outlets.
There are four lines on the abs pump,two to the master cylinders and one to the front calipers and one to the rear.You need to remove them all,blank off two and,on the other two,use the link pipe as a bypass so the abs pump thinks it is still connected.
