I have a 2004 Monster 620 (still has paper tags on it!) and I just changed the oil for the first time. Now the Oil pressure indicator light is on and I have gone over everything and can't figure out why this is happening or how to fix it. I called the shop and the mechanic & I went all over everything I had done and he can't give me a reason or solution, so just bring it in and he'll look at it. The bike is still under warranty but I don't want to drive it to the shop with the light on. Has anyone ever heard of this? Anyone have any ideas as to why this is happening and how I can fix it before I have to load it into the back of my truck and haul it to the shop?
