I have noticed a couple of spots of oil on the garage floor. The oil appears to be coming from the crankshaft sensor and tracking along the under side of the primary and dripping off the lowest points of the casing. I know this sketchy info but is the sensor leak a big deal or just an o-ring renewal, service e-book doesn't really mention anything about it. Any help or advice will be much appreiceated. DB 

clean the bike  then put some talc powder around where you think the leak is  run the bike then look for the wet spot  to make sure it's were the leak is don't be shy with the powder it will  wash off easy
