Hey guys...I apologize if this is the wrong section but can you please let me know if its okay to leave the oil in my bike during winter storage or should I be changing it? the last oil change was done at 800 km and the bike now has 1800 km on it. When I got it serviced at Kahuna the guy told me to get the next oil change at 3000 km and that's why I am asking this here. Appreciate any advice.
