685 kit plus freed up airbox, slightly cleaned up intake port, opened up stock exhaust, Runs much smoother, and only needs a tiny bit of oil (probably averages 1 ounce per 300 miles) when I run it over 5000 RPM for sustained periods. Somewhat more power, but not anything that would keep a KTM 790 in sight on a long flat straightaway.
With modified windshield & seat, the bike is very comfortable and I could ride 12 hours a day at 75 mph if needed. That’s what puts miles on the clock, not 100 mph with reliability, tires, deer or law enforcement issues.
Suggest you add a 16 tooth countershaft sprocket plus fresh chain and go for it.
