The cost would be nearly equal (upgrade wise) to a Carpenter install. About $6k plus exhaust. Apples and oranges. Both cool, I’ve ran both, to some it’s not just which is faster. The M8 is an awesome power plant, as is our beloved triple.
I have to wonder if the M8 with 131 displacement and stage IV is going to stay cool enough with oil cooling and the twin cooling.

What a quaint idea, comparing a brand new, high priced HD with a 15 year old bog standard Triumph.

Probably the most interesting thing is that they were able to find a bog standard RIII.

Well the warranty be the same standard two years. on the 131. Next question are the same standard engine cases being used on the 131 or did they design a different engine case for this bike. What motor Compensater did they use? Did they increase the size of the oil pump or just use the standard. Last question did they include a oil cooler.
