I purchased the 52 T Vortex rear sprocket for my 03 KX 250. I am trying to use the stock front sprocket. However, the chain is not seating on the rear sprocket. Is the stock front sprocket not compatible with the new rear? If not, will the vortex front sprocket correct the problem?

It shouldn't matter if you are running the stock front sprocket. There could be a couple different issues if the chain isn't seating right. If you are using your stock chain, it could just be too stretched out. The only other thing I could think of is if the sprocket's teeth are somehow off in spacing. I would recommend picking up a new chain if you haven't already done that, or contact Vortex to see if this is a common issue.

when your going to buy a new sprocket or chain its a good ideal to go ahead and buy both front and rear sprockets and a chain at the same time because these parts wear together,your chain is probably just to stretched to fit in the new sprockets teeth.i would go ahead and get a new chain and front sprocket if i where you
