Default XR steering trouble shooting

Hey guys! I'm maybe a month and a half into this ridiculously awesome and totally expensive crawler hobby and I'm loving every second of it. That aside. I've ran into a snag, and although I've found a temporary solution I cant seem to figure out what is going on exactly. I'm hoping that the seasoning and expertise found on this site can help. (a$$ kissing session complete )
Here's my setup:
Stock steering
Hi-Tech 7950th
Aluminum servo horn (cant remember which brand)
Airtronics MT4
and I have the Caster (I think thats the right term) set back one click sitll using the stock holes that are into the knuckle mounts.

Problem: The steering on my XR travels significantly further when steering left than when it does to the right.

My Solution: I adjusted the right steering EPA to more than 20% higher than the left EPA. It's a quick fix and works but I might run into problems later because of it.

Question: What could it be, mechanically speaking, that could have such a huge impact on the way my steering is performing?

Thanks a head of time!

My EPAs are at 80 and 120 to compensate for the difference. Nothing wrong with it that's what the EPAs are for. You can adjust your drag link and servo horn to try to compensate for it.

typically the length of your steering link from the servo to the knuckle would effect this.

Check the screws that thread into the steering bar. Depending on your motor/gearing, these screws can hit the motor can and limit the steering throw quite a bit.
