Skully,
Now that you have about 6K miles under your belt with her, now is a good time for a general check up. A thorough shake down would include checking bolts for proper torque, check all fluid levels and a good performance tune. If injected with ECM control then you are limited on what or how you can make changes. The clutch cable is already dealt with.
I like a 180* T-stat but something as simple as a bad radiator cap could cause her to run a bit hotter. A performance tune would find optimum ignition timing, verify timing tab/pointer and check or set air fuel ratios and more. Some of these issues can make engine run a little hot although I doubt
oil viscosity would add 20 plus * to average run temp. Jeff C
