Well after getting evacuated out of Libya over the last week or so if was nice to get back and pick up my bike after outing it in for an ECU flash and Dyno. I'm running the 57 mm full system and on my previous R it made about 145bhp, so I was more than happy with 147 at the back wheel. Also pick up of the throttle is greatly improved and it no longer hunts on a constant throttle. I'll see how it goes over the next few months but so far, well recommended. Just need to fit the carbon air tubes now and fit another expansion bottle. ( any tips?)
