chain prob

[uncle porry]

got a prob with the chain on my zxr400 track bike (apologies for putting this up in this section, but anyway)....with the bike on rear paddock stand, i spin the back wheel and it gets to a certain point when the chain goes very tight and the wheel will not spin freely....it seems to do it when a certain part of the chain goes around the front sprocket....
any ideas ?
thanks

Sounds like the chain has a tight spot, gonna need replacing I'd say

The true technical term is 'ITS KNACKERED' by the sounds of it.
