In May I put a mod rear dom on my xsc and it made a noticeable difference in performance" Nothing to write home about " .My carb is a pile o crap that will never hold a tune! So I sat in my grass and messed with it for a bit till it did something I have never seen before. Massive low -mid range power and shattered a front diffcup on grass. Can anybody tell me how much more durability tempering will give these cups
