Rokslide team,

I am looking for some bow tuning assistance. I picked up a used RX-7 ultra. It has the Grey shims installed but won't shoot a bullet hole unless the rest is near 1 inch from the riser.

I found a tune chart and it says to install the black spacers but I'm not sure which kit to get. The only one I can find is $60 and I'm pretty sure I only need 2 shims. (4 max) The cam says HBX pro.

If anyone has a link to the correct spacers or has a box of old ones left over I'd appreciate the assist.
 
I'm assuming 3/16" axles? I will look when I get off work tonight.
What kinda tear are you getting Screenshot_20241024_080554_Drive.jpg
 
I found that exact chart. I'm a left handed archer, getting a tail left tear. With my rest set at 13/16". I had to move out all the way out to 1" to get a bullet hole and to me that is unacceptable.

Current shim configuration from the back of the bow is both thin Grey spacers on the left side of the bow.

I think the corrective action is to install the black shims to move the cam further left.
 
What is ur center shot. I've found good luck around 3/4" on my rx8U. I will look tonight after work. If I have some i will pm you for your address
 
I appreciate the help, a local contact was able to get me the shims. I'll try to install this weekend and report back.
 
After installing the black shims on the bottom cam the bow is shooting bullets with 2 different arrows and a bare shaft.

Great success
