I've owned an H2 since 1978, and trust me, that's not a 750 and it's not a 500. They have nine horizontal fins on their cylinders. The 250s, 350s, and 400s have seven fins on their cylinders, although the bottom one is hidden in your photo. A 400 has very square looking heads. The photo below is of me on my H2 a couple years ago. You can count fins if you like.

Ramjet, yes, the Jennings and Bell books are old staples of tuning.

Correction: I don't have any S1 cylinders here, but I thought they were externally the same as S2 cylinders. They're not, S1 cylinders have six fins, and other photos of that triple, like the one on the right below, on http://notyouraveragebikes.com/ clearly show six fins, so that's definitely a 250 triple. I guess that might qualify it as a Ninjette, but it was rated only 28 hp at the crank, so somewhat less power than our 4-stroke 250s.

At about $7,300 US, I doubt if it will sell very soon: http://notyouraveragebikes.com/our-b...h250caferacer/
