if the back wheel is not straight, it can cause the problem also. make sure you are tracking true.


#1 You can do a pretty decent alignment check with a competent helper, center stand or jack, a string and a tape measure. Get your bike plumb as you can (shim if necessary) and stable, bungie your H.bar ends so your forks will aim straight by themselves. From low on the back tire, have your helper hold the string as to alignment back to front and continue on to the front tire. Measure the gap as parallel to the front tire left and right sides. I can almost guarantee you will want to be moving that rear wheel one way or the other, first, the string don't lie. Once you have the back straightened checking the front is a snap as described
