i installed a 12 port fuel injector and an ECU from the off road model.
it has helped tremendously.
stock 2012 TE250 4 port fuel injector
upgraded my bike to a 12 port fuel injector...
upgraded to a different ECU
cured the "flash out" problem.
used the laptop to further improve the bottom end response of the bike.
now running 12T front and 52T rear.
