How easy would it be to change from a black top VTR to a silver top VTR i know they are basically the same but i think they have a few more engine sensors than the black top. Can anyone help please (all help welcome).

I mean the engine forgot to mention that part.

its very easy to change them there the same engine bar like u say the differences in the sensors.
i just can't c why u would bother tho??
surely if u were to do an engine conversion a vts lump would be the natural step to take

or now that i've thought about it why not just swap the rocker covers!!!! job done
