Straight up, I would fit an end can to knock off the weight and give the twin sound, avoid remapping and sort the intake system out depending under what conditions you ride..the rest save your money for riding kit or, for the 1290SAR..chasing power on the 1190 is an utter waste of time and effort when you have out the box, the 1290 ready to go
KTM- When you first hit the starter button the engine just sounds pissed off. Below 3000 RPM the Yamaha is more civilized and less "cammed up", but the KTM never feels labored. Its easy to ride at low RPM and the throttle response is fantastic. After 6000RPM hang on to your nipples. The intake valves are supposed to be between 0.004" (0.10mm) and 0.006" (0.15mm). (NOTE: all of my exhaust valves were in spec) Imagine my shock when I couldnt even get a 0.0015" (0.04mm) feeler gauge to fit. The valve rockers were touching the cam for the entire rotation. It gets worse, my only option was to grab an assortment of shims to see PARPR.
