hey, bike is working like junk, spittering and sputtering, back firing through the efi carb, and when you hold it wide open, it revs up fine, bit as soon as it hits its rev limit, it starts to bog down right away, all the way till it stalls out, here are the codes I read on the screen.
12, 41, 42, 22, 45,43,55,61

I found out that 61 means nothing, just end, but unsure of the rest, any help is appreciated, thanks

 

it also wont go any faster than 20km;s per hour, it just starts dieing out, thanks agian

 

try this link for the ECU codes

Test your battery, a shoddy battery can drive the ECU nuts.

 

I GOOGLED my codes and found a list try it
