I'm loving my UK-spec 2009 WR250R but like many I'm looking for a touch more "oomph" to help on hills, at altitude and on the trail.
Could someone give me a basic list of farkles starting from the smallest thing and working up towards the pricey? Does it start with airbox or programmer, sprockets or pipe, etc etc?
If it's been written up already, apologies and please point me in the right direction.
Thankyou in anticipation!
John
