2011 Klx 250s and fmf exhaust question, help please!
An 09 and up FMF pipe should fit as well as a power or megabomb of the same year will also fit. But you will have to read the directions before you try an install it or you will never get it on.
hay mike,just curious of the upgrades u did and how much better it performs. i just purchased a 2012 klx250s, and im confused by all the info on these fourms i want to do the mods but so many conflicting opinions.. the only thing i did so far was put on a FMF powercore 4 slip on exhaust.. any info would be great! thanks

How was it with just the exhaust. Any loss or gain in power? Did you rejet? Thanks.
