Bought a 2013 husky tr650 strada. I wasn't able to take it on the highway because I wasn't comfortable being the heavy traffic with a bike that wasnt mine. I was told there wasn't a single issue with the bike other than it may need tires soon, which was obvious. It started stalling out. It would get to higher rpms and it would stumble. I almost dumped it because of the stall. I put new gas in it, new oil, new plugs, and changed the air filter thus far.
I recommend putting a ground wire on the ECU also. I had an issue with misfiring and a CEL in the higher RPMs, running a ground wire from an ecu case screw to the negative battery terminal fixed it. Also provides some safety from accidentally shorting the ECU and bricking the bike.
