Ok so here it is ... i went from a 2001 wr 426 to a brand new fi 2012 wr 450. I thought this thing would be awesome, but i am dissapointed. Yes it has been uncorked. Here are my problems..... it doesnt like to start very well and it if you drop the throttle to fast it dies.... doesnt seem to pull as hard as my 426 either but it is faster. I believe that it is just too lean. My dealer has changed mapping and it does run better... but still has flame out...... whats the best fix? Can i fix this if i buy the programer or is there someone with a reprogramed fuel controller to fix this?
