I have a 00 300ex and I am putting 18x11x8 turf tamers on the back, the tires on there now are the stockers that are 22x10x9, what tooth sprocket do I have to put on the back to get the low end and mid range that it needs with those smaller tires??, thanx for any replies

 

It'd be easier to figure out if you mentioned what sprockets you currently have now. I don't know the 300EX well enough to know.

 

You could either put a 14 on front or a 36 on back.
