That looks like a top quality job. I had better results across the rev range with a short inlet tract. I did have the bracket for the voltage regulator cut-off though so longer might be necessary if its for road use. I had to make a flange as well as I was told that welding the stock flange was a bit hit and miss because of the high zinc content.

I cut the inlet length so that it would be 31cm from the valve face to the bellmouth intake which is the resonant length that I needed. I know a good tig welder who can do the job ok
