Hello, I bought an 03 cr450f about a month ago, and have put close to 30 hours on it in that time. All hours have been trails ranging from heavy sand to rocky hills. I have been changing the oil on both sides every 10-15 hours. Engine oil comes out honey, clutch oil comes out burnt, and gray. I am using HP4 in the engine, and honda pro gear fluid (the red stuff) in the clutch. On my ride last weekend, and my ride yesterday, I noticed that the engine has been 'easy' to kick over. Like there is not as much resistance on the down stroke of the kick. And for my ride yesterday, the bike was hard to get started, it took like 5-8 kicks before it would start, and this was AFTER it was warm and had been riding around. When I first got it, it would start pretty easy like 1-3 kicks. This is my first 4 stroke, I am coming off of a yz250 so Im not sure what all these symptoms mean. And I have not torn it apart yet....I wanted to get some advice as to what could possibly be going on inside my bike. Thank you for your help.
