I recently got a 1985 or 86 (The year on the frame is partially rubbed off) 250 big red and I kicked it to see if it would crank because it had been sitting up outside for years but when I kicked it it wasn't very hard to at all and all I could hear after was clicking so I was wondering if anyone could tell me what is wrong with it.

It's broken. Seriously??? A little more info will help you ,and us ,greatly! It SOUNDS like it's been run out of oil,and the rods broken.. Do a compression check,if there is none,shine a flashlight in the plug hole,if the piston isn't going up and down when you kick it. The rods broken,could also be the timing chain ,,or other things. And welcome!! btw : )

Not alot to go on here..are you possibly talking about a kick start problem..

If so you will have to remove the side cover and check the gears..

Have you tried jump starting it with a boosting battery charger or your car?

Post a pic, we can tell you the year... Sounds like your one way bearing went and took a dump on you... Pretty common on these motors....
