I fitted the Rapid Bike Evo as it seemed to tick the boxes I wanted, It self learns off your O2 sensor and you can easily self program the fueling map off your laptop. I have a Racefit can and it runs lean I fitted it in winter but I don't like starting it as it just puts acid in the bores and oil when cold So I took it out today and what a difference, the flat spots have gone, the snatchy throttle has gone that I had just put down to being a big bike, it's just so much nicer to ride it runs a lot cooler in traffic, probably down to more fuel going in but shows how lean they run with a can I am very impressed, and I got it on offer in the winter for £280 as time goes by it self learns the fueling to your riding so may get even better
