one will take large amounts of money, the other is a link to buy camshafts.yeah, i get confused on which one i like to go to the most.
You can also add an emissions block off kit. That seems to be the popular mod for that bike. http://www.motosport.com/dirtbike/2008-honda-crf250x--APPLIED-EMISSIONS-BLOCKOFF-KIT
Rejetting the carb and opening up the top of the air box are also things to consider.
sounds like the best of both worlds. i think more people who are cross country or trail would like the stock x better than the R's they usually buy and let set.
