Does anyone have a set and true way to measure and make sure that the rear tire, and the front tire are in perfect alignment with each other? This is why I ask, we bought a brand new 650 R, and couldn't figure out why it kept throwing itself to the left when going through a hole, after many hours of scratching our heads, we came to the conclusion that the swing arm was an 1/8 in. longer on the right side than on the left. This could be from it not being welded at the factory right, either way its off. Another finding is that the frame stretches and could be up to an 1-1/2 in. longer than stock if it realy gets rode hard, ya might want to check that when buying one, used. any input is appreciated.
