This engine has a rumble , not sure of exact problem yet hence why its being removed , 
ill do an engine strip down post on this engine .

this si how i took it out not so professional , i have not got a ramp any more had to sell it last year 
, saving for one now so it makes it easier if you have one , also it might be better to do it slightly different 
we all have different methods and most of the time i do thing slightly different myself .

easy job , minimal tool ( no fairing which is great !! ) , the only problems i see is 
mixing wires up i have had a few bikes bought to me with fault codes for fault on injector and all its been is 
mixed up wiring , so be careful if you remove wiring to note which goes to which .
injector wiring connectors are both black !!
