I'd clean it up, change the fluid, and ride! Unless it's leaving a puddle on the ground, I wouldn't be too worried. Cleaning, filling, and riding is the easiest way to test it. :cool:
Those slow leaks can be hard to find. I have a couple going on now. Soap and water will work, with lot's of patience. The last new Bridgestone I carefully mounted a couple months ago, has a small leak somewhere. Takes a couple weeks to go down, so I just air it before I ride, and say screw it...
OK, because I'm too old and too lazy to hunt, if you put a "check" mark in the O2 sensor on Tune ECU, does that activate, or de-activate the O2 sensor ????
I have 2, 05's and 1, 2013 and there is a difference in the two. I'm too lazy to go measure at the moment, but will watch to see if any others test their bike. To me, the 2013 shifts a lot smoother than the 05's. Don't know why, just so...... And that bit of "slop" will bite you on the ass in...
Triumph might want to look at what's happening to John Deere, after they started making their tractors harder, or impossible for the owner to repiar or modify. :cool:
