I have a Rekluse pro model and was wondering if anyone else running one noticed their oil to come out much darker since installing it? Currently using the suggested Rotella dino 15W40. Clutch is set up correctly and is on the med/hard setting. Ride only tight single track and change the oil every 100 to 120kms. Bike only has 900kms on it (500 with Rekluse). I emailed Rekluse and they said not to worry about it. Should I be?
