The backfiring comes from the throttle plate being slightly open letting fuel into the chamber after letting off at high speeds, causing a backfire. If you adjust it at the governor you can gain some speed but just don't over do it. Kenny is right, check the belt first,and he may have mentioned feeling the clutches for wear, they may need replacing if worn enough. You can add a little larger tire to the rear, you can do all 4 if you wish, but a little stance is nice too, and you'll gain top end speed. May be a little slower at take off but it will get right up there in speed. Do it correctly and you can have both without any backfiring at minimal to no cost. I personally would avoid zip ties, may be a personal cart, but do it the way you would if you're the one whose job is on the line. Properly done, if someone gets injured it takes away any finger-pointing. Just my thoughts.
