I just got my self this BRB p/s liner from kitracer (Chris,thanks by the way).This is my first 3 ports liner as I m usually using 5 ports. I m putting it in my NSR case. Its very interesting design and very well finished. I m breaking it in at the moment, and so far so good. I will be using it for our upcoming big race here in early March and will keep you posted on the performance later.
