    I've seen the stock 144mm yami pumps crack/fail with the triples we are running in Sport Spec Open. I am running a Solas stainless pump in my 1200 B1. With those high revs and hp you maybe stressing the oem pump! Get it repaired before it causes you serious damage! I would try the warranty first and see what they say.

    there was a long discussion on the forum and good info and fixes for that. Try the search function and maybe you can find the thread. As I remember, everyone was just grinding out the cracked chunk area, smoothing it down and keep on riding. No performance loss noticeable.

    Time to ditch the weak factory cast pump and go stainless! Order up a Riva!

    I just don't like the 160 mm pumps ... So rocketman you don't recommend soldering ...
