Thanks for your feedback, I will keep making these 690 O2 controllers while there is still a demand.I have a 2012 690 Duke, GPR exhaust and just installed Kev's 02 mod. Delivery took 10 days to Russia. Installation was very easy, about 15 min and then 15 min reset. Amazing impressions after first ride. It's so smooth on low RPMs and bike became so friendly, especially after switch to Soft mode! Just cruising and relaxing! Now map-switching really makes sense. Hooligan at Advanced or nice guy at Soft.
