I agree Ken.
The thing about V-twins is that 45 degree motors can only be balanced for one rpm "range". Most are in the mid 3's for that perfect balance.
A 90 degree V-twin can be balanced wider range of rpms.
A 56.25 degree still has balance issues like the 45 degree motor and as such it too will have a "sweet" spot in the rpms that it will be velvety smooth.
Now take the Harley "B" motor, it has counterbalance shafts and it can be balanced and mounted solidly in a frame and be perfectly smooth. And for this, it costs hp as all the rotating mass take hp to turn.
I envy all you guys being able to ride in your M3W's while I'm still contemplating the investment that I don't have the funds to undertake. I'm not going to borrow money to get a toy. I'm too close to retirement and I have other priorities at this point.
So I will continue to live out my fantasy through all of you guys having a blast with your cycle-cars.
