I've never make any drawings with sizes so you should measure and make them yourself.  The "problem" is the size of the engine, an oil cooled engine is shorter so you get a gap between the engine and frame

example of  my (ex) gsx1100e,  but frame is the same size as a 1983 (correct me if a am wrong)

the gap between frame and engine

 

this was my solution

 

 

[Whoo hoooo! There's a water cooled section.....]
