i traded my 400ex yesterday for a banshee.So far liking the banshee but its got some jerryrigging. its not in the greatest shape but it has potential. its basically stock with tors delete and a shitty boost bottle and rims. besides some worn parts theres something thats worrying me, the chain would go from slacked to tight.i took the chain off and when i spin the front sprocket in nuetral it will stick at a certain point but when im riding it i cant notice anything...any advice?i torqued the nut on the countershaft and its just csticking a little now its not going tight as much anymore.
