I have three totally different areas to questions. First, is your front track wider then your rear? When installing after market wheels, they are usually wider or offset more then factory wheels. The rear SHOULD be slightly narrower then the front.... Second, have you re-adjusted your clutch? A new clutch requires a few adjustments till it seats in. A loose, slipping clutch can cause the rear tires to shutter.... Third, re-adjust your shocks to proper preload, then adjust your chain, and remove your swing arm skid plate. Sand packing in your chain can cause it to shutter, tight, loose, tight loose, etc... No number for this question, and not personal, how much do you weigh? Over 250lbs may require better shock valving and springs.
