Alright so I recently purchased a Honda fourtrax 250 ultility bike. Engine works great one was bearing is great. However I notice when it's cold I hit it into 1st and the tires will spin. Go into second and they try to spin but the engine just isn't grabbing you can rev the **** out of the engine and it won't spin the tires. Go into third same thing. Doesn't bog at all. It's like the clutch isn't engaging. I recently changed the oil with 10w40 motorcycle oil.... Another thing is the shifter sticks down sometimes and doesn't always shift when you pull up. ANY HELP APPRICIATED! Thanks

 

Did you make sure that oil is clutch safe? Had teh same issue with a old king quad. Turned out the previous owner was using the wrong oil. Several oil changes later it was better.
