It's a 2012 model and just did an oil change, filter included. Drained it all for 10min then filled it with 1200ml as is stamped on the filter housing. Went for a ride and there's oil leaking from the throttle body on the cylinder side. This was not happening the previous ride when I purchased it. Not too savvy with the set up of motors so wanted to know if this would be normal if there is too much oil? What do I need to change to ensure not to put too much next time? Was 1200 exactly and bike was level when drained.
