Benchmarking a car engine is definitely a good idea but benchmarking a bike engine no so much (in my opinion) since they alwas fall for the power appeal.
Fitting a cam phaser sounds good but DIY it on a bike engine, not so much.
Also rules out all the central cam sprocket engine (Suzuki oil cooled engine à la GSX-R)
Maybe the very low weight of the bike can outcome the narrower power band ?
