Just purchased a Bonanza 1300 it has a tav2 now my question is the converter connects directly to the sprocket on the wheel and I have seen pics where the converter connects to a sprocket that crosses over to the other side then to the wheel sprocket what is the reason for the cross over. And also when I sit on the bike my weight move the swingarm up which loosen the chain. Should I look for sprocket bar that crosses over are is there a repair for my chain gettin loose. Thanks
