Just The Heads

The absolute best bang for the buck is an 883 bored out to 1200 and sporting a set of ported heads. This conversion will yield more horsepower per dollar than anything else that can be done to any other Harley-Davidson.

We use the same sized valves as used in the 1200 heads. A 1.715" intake and a 1.480" exhaust valve. With the port work done, these heads flow much more than a stock set of 1200 heads BUT that isn’t the only reason why they make so much power. A healthy boost in compression is gained by squeezing that 1200cc motor into the small 883 combustion chambers. We are able to get 10.5:1 with this combination.

One of the nice things about this combo is it’s ability to use stock cams. Of course you can use hotter cams but it isn’t really necessary. We suggest rejetting the stock carb and using a free flow air cleaner, ignition change and a good set of pipes.
