CVO Technical > Twin Cam
110 specs
(1/1)
Kowboy:
A quick question here:
Is the stock CVO 110 considered stage one (50m throttle body, SE exhaust) or not??
HD Street Performance:
It is a large bore 103 with different, larger, heads and a fast lift rate short cam.

Well, they are supposed to be and then some ...
'Technically', using the simplest formula below. The 110 SE is a 'Stage 3' version of the 103 motor from the factory.
They are about a good as you can get 'stock' from the dealer (without going to a 'crate engine').
The CVO air cleaner is better than the stock one. (Wild claims are made for many aftermarket ones too!)
Add a complete exhaust system, not just slip-ons and a tuner and you will have gone about as far as you can for a Stage 1 (or factory Stage 3 with-out splitting the cases).
