Only cuz you axt:
I believe the 19 is too tall, and you will hear the con rods rattle when you launch. I did anyway.
For the highway though - very sweet ratio
'round town - I think if Triumph would become non-secretive to their customers, (i know - that's a good one...) you might get a driveline engineer to allow as how 19 is mighty tall for these little engines / torque curves.
Just my ought 2...
