hi guys
looks as if the majority of the excellent research into power/torque mods has been directed at carb and synonymous mods
i run a Japanese built 2011 klx250S with EFI
DOES ANYBODY HAVE ANY EXPERIENCE WITH TUNING TIPS?
i am going to run a 13T front and possibly a 48T rear as all I am interested in is some off road riding
do I need to do any MAJOR ALTERATIONS if I change the header and muffler, air box intakes. Air filter ?
please advise as I thought the whole purpose of efi was to take care of different O2 etc readings and just do it all automatically?
many thanks
phil
p.s anybody interested in off raid penang northern Malaysia Ipoh taiping southern Thailand riding?

 

When off roading, focus on suspension, not maximum HP, cause you didn't make that choice when selecting a moto.

 

If you change to a KDX200 snorkel or remove the original, get one of these:

And do this to derestrict the rev limitor:
