At a Datsun day a couple of years ago, I was talking with 2 other people running 40mm triples on stock L24 with extractors and we all had 95 kW at the wheels give or take 0.5kw.so close in comparison..
I have no idea what a completely stand L24 would put out on the dyno.. But some one else might be able to ad this info, I'd be interested to know
