02 cr250 chain sprocket

[SmogNazi]

Hey guys0

I just bought a PBI 51T rear sprocket and think i should replace the chain and front sprocket and chain guide. Should i just go with the matching pbi sprocket and chain and get a pbi chain gaurd? I believe the front sprocket is a 13T stock, im going to run a fmf gnarly, lightening coil and flywheel weight, im going trail riding :-) any suggestions feel free to post :cool:

I have an 03 CR250 and run a 50 rear stock 13 front with Gnarly pipe. The gearing is perfect for tight to open woods riding that I do.
