GN250 chain issues?

[Lower]

hey all
Having a few problems with my Gn250 chain. First bike so I'm learning as I go. I've been keeping the chain well oiled but its becoming extremely lose to the point where I can hear it hit the chain guard. I did a quick google and watched youtube videos and thought it seemed really easy. But for the life of me I can't get the axle bolt off. Even if I resort to standing on it, it won't budge.

I really don't want to take it into the shop and would rather learn to fix everything on the bike myself. So any pointers as to where I'm going wrong? I've tried crc all over the bolt incase there was some rust build up. Is this normal? all the videos I've seen show the axle bolt getting loosened by hand.

and yes, I'm turning it the right way

Although it very rare, the nut can sieze on the axle. I had this happen on a bike less than 6 months old. If this is the case then you will need to order a new axle and nut (not expensive). The nut may need to be split to remove it from the axle.

You turning it the correct way? Righty Tight Lefty Loose

You turning the nut and not the bolt?

Some nice Welly KBer will no lend you a hand.
