Last week and for about the 10th time I checked out the crazy little v8 engines that use two 4 cylinder heads from big Japanese sports bikes. A lower powered one makes 350hp at 10k rpm and the whole engine weighs about 230lb. Yup. And I again wondered about a detuned version with cheap OEM parts - by aviation standards - and a decent TBO…
If Yamaha is casually asking the question, I’ll be interested to see what they find.
