vn running dirty

[project vn]

hey fellas,

quick quistion to any one that knows about vn's... i just put extractors on my vn and its running dirty missing when i put
me boot down. thought it might have been the spark plug leads so replaced them but no good. i used the old oxigen
sencer that come of the manifold that was already on it thinking it might be that or needs a tune.... any ideas ?

first before anything double check your firing order make sure you havent mixed up the leads. done the plugs themselves? could be that too. if its still missing, maybe do a self diagnosis see what error codes come up if any...

Does it have a extractor leak at the heads?
