On all the Bullets, the modifications require a full attention to the power making aspects. It's not just some simple one thing that is easy to do.
This is no different with the UCE, except that we seem to be able to work with the stock bottom-end as it comes from the factory, and this greatly reduces the cost and labor to do some power upgrades, because we only have to work on the top end.
It comes down to improving breathing, and improving compression when possible, and increasing rpms.
The factory does an adequate job for the power making design in the engine, for the intended goal of the motorcycle, from their point of view. They don't do anything "wrong", but they apparently aren't aiming at high power. So, it's a matter for a person who knows how to modify cylinder heads to go in there and make changes to the flow paths inside the head, to increase the flow in the proper ways. This requires some expertise, because it's essentially a partial re-design of the engine.
After seeing the UCE head, and working with it on the flow bench, and generally assessing the design, there is potential for plenty of power out of this platform, when properly modified to reach that goal.
I feel it can be made to deliver power as well as anything we have done with the Iron Barrel models, which is considerable. And I think that it has potential to do it at somewhat lower cost than modifying an Iron Barrel to the same levels. Not necessarily a "cheap" modification to get the power up, but not as expensive as we have seen in the other models. Of course, the higher power desired, the more cost it will take to get there. But, these UCE engines don't have to be low power output if the owner wants to undertake a modification program on them. We have several in the shop right now, undergoing various stages of modification. They do respond to the correct approaches. They can make power.
