Here is a video and a guide to help you with spacer tuning your new HBX cams. https://hoyt.com/new-spacer-guide?mc_cid=6c52015841&mc_eid=UNIQID
Each cam and limb model is specifically designed to work together with the particular bow models that they are built with. While some cam and limb models may have similar dimensions and physically “fit” on another bow, adding those parts can cause negative effects to both the performance and the safety of the bow. Hoyt does not recommend using any parts on a bow that were not originally available on that particular model from the Hoyt factory.
Hoyt recommends that a modern synthetic (Dyneema, Fast Flight, etc.) string for a high-performance bow have not less than 15-20 twists with a suggested maximum of 1 twist per inch of string length. This promotes a rounder, more consistent string.
All Hoyt recurves are engineered to work with the latest high-performance string materials. We have extensively tested and have had good results with the following: Angel Majesty Brownell D75 Dyneema Brownell D75 Thin Brownell TS1 BCY Dynaflight 97 BCY 8125G or BCY 8190. Any of these current materials can be used to build an excellent recurve bowstring. Please consult manufacturer websites for additional information on these string materials.
For instructions on how to properly adjust recurve riser alignment refer to the Recurve Owner’s Manuals at: http://hoyt.com/product-manuals/recurve.
It is a simple matter to return your Hoyt recurve Hardlock dowel to the factory zero position. The installation of two alignment washers on the solid end of the dowel (the opposite end of the dowel from the screw and cap), and insertion of the dowel from the sight window side (top and bottom are not interchangeable) sets the dowel back to zero. Place unused washers under the cap, replace the locking screw, tighten the system down, and you a have a factory-fresh setting- which is all you need in 99.9 percent of setups with Hoyt limbs. Full details can be found in the Recurve Owner’s Manuals at: http://hoyt.com/product-manuals/recurve.
Weight adjustments can easily be made by turning the weight adjustment bolt or limb bolt (tiller bolt on recurve bows) clockwise to increase weight or counter clockwise to decrease weight. You should always turn the top and bottom adjustment bolts in equal amounts. Be sure to unstring recurve bows before making adjustments.
To find out which arrow is the best to shoot with your setup, visit www.eastonarchery.com and click on the Shaft Selector Guide. This will walk you through a simple step by step process in order to find the shaft that's best for you. Hoyt bows should not be shot with arrows weighing less than 5 grains per pound of draw weight. http://www.eastonarchery.com/downloads/selection-charts
Hoyt recommends that you never exceed eight complete rotations of the limb weight adjustment bolts from the bottomed out (maximum weight) position.

On most Hoyt bows the maximum number of turns that you can turn out your limb bolts is eight (8). The Hoyt Ignite model bow can be adjusted out ten (10) turns. The amount of weight that you will lose varies from bow to bow and turn to turn. The only way to know how much weight is being lost is by measuring it on a bow scale.
The string and cable lengths are normally listed on the limb sticker located on the limb of your bow. If this sticker is missing or illegible, you can go to Hoyt.com and research the tune charts for the correct specifications. Please visit the Compound Bow Tune Charts page. http://hoyt.com/tune-charts
