Since I am doing more street riding with the KLX these days - considering taking off the 13T and putting the 14T back on and going with either the 14-43 or 14-44 sprocket combo. Questions are: Will I need to replace the chain? Who makes the 43 or 44 tooth rear sprocket to fit the KLX and who sells it?

 

i have a sunstar steel 14/43 on my bike works well with this little motor. PS STOCK CHAIN.

 

Our rear sprocket also fits these bikes:

1997-2007 KLX300A7F (KLX300R)
2008 KLX450A8F (KLX450R)
1997-2007 KDX220-A7 (KDX220R)

I just got a rear renthal from these guys. Free 2 day shipping on orders 150.00 and over. Sprocket's almost $70 I think.

Renthal part number is 112U 520 (# of teeth) so my 48 tooth is part #: 112U 520 48

 

Thanks for the info!
