If they aren't careful folk will turn away from car racing if they persist with electric... Bikes have realised, not a great deal of development going into Formula Zero and they, ve lost top riders...Not all Morgans had the J.A.P. engine though, there were the Matchless engined ones, MX2 air cooled and the best one, the MX4 water cooled. I always though the Brough Superior with the MX2 engine was the best one too.
However I don't like the sound of any of the V twins, or American V8s, or twins of any variety. Or singles, I definitely dislike the sound of the Manx Norton. Give me the howl of the Gilera four anytime, I'm definitely a multi-cylinder fan in locations where noise is appropriate like race tracks.
The worst of all sounds? Definitely Formula E, I can't stand to watch it and endure that horrible discordant whining. Motor sport for the chronically deaf.

I certainly wouldn't go to IOM to watch electric bikes... Its just not same...
By the way, I agree about noise... Gilera 4 is superb. With the Inter Norton it's the whole picture. The bike, what it represented, how it looked and listening for my dad on his... Listening to one coming down road is an experience tho...
