hello someone please help me I got a Honda 2010 420. My a TV starts up shifts but won't move. It kinda jumps but won't go. When a TV is off the ground the wheels will move. My brother had added in gear oil but nothing. I really want to get my atv started because I miss giving my kids rides on it. I let my dad borrow it and when brought back it started to act like this.

 

Is it 2 or 4 wheel drive? If 4wd and neither set of wheels is getting power it is most likely a worn out clutch. The bike has two clutches so it could be either one. A conventional motorcycle multi plate clutch is worked by the movement of the gear pedal or electric shift motor. This is adjustable with a screw and locknut at the front of the clutch cover. The other clutch is centrifugal, like a lawnmower, and works by engine speed, this works fine until the lining has gone and then slips.

If 2WD or just the back end is not getting drive, it could be the axle shaft failed. This is common on 420s, if the prop shaft goes round but the rear axle doesn't, the splines on the rear axle shaft will probably have gone.

 

It is 4wd. when i put my atv on cinder blocks and put my atv in drive the back wheels started spinning But wouldnt spin when i put back on the ground. Is there a way to tell if one or both clutches went out?

 

The important bit is what are the front wheels doing in 4WD?
