OK, I got my '97 RK back together in early February and have been tuning the TFI for a few hundred miles. I changed the inner cam bearing, installed Andrews EV-13 cam, stage 1 air cleaner, S&S reed breather (works great, no oil carryover whatsoever) and TFI 1040 ST tuner. Stock exhaust. What I've settled on is: green, 2-(pointer-width under 2), yellow-4, red-6, rpm-4. Last tank of gas, going easy on the throttle, 50.4 mpg. This was mixed riding, mostly 4th and 5th 50-60 mph. The green setting was the most critical to get the mileage up. It is leaned to just before it starts to run ragged. I could also notice the exhaust smell was less noxious when I got it where it is now. Still pulls nice when the cam comes on about 3000 rpm, and decent low end torque too. Thanks Dobeck!
