I INSTALLED MY TOW-PAC TRIKE KIT ABOUT 4 MONTHS AGO AND I LOVE HOW IT HANDLES, GREAT RIDE. THE PROBLEM I AM HAVING HOWEVER IS THAT WHEN I HIT A BUMP, MY MUFFLER GUARD STRIKES HARD AGAINST THE REAR BRACKET THAT COMES DOWN FROM THE FRAME TO THE TOW PAC UNIT. HAS ANYONE ELSE EXPERIENCED THIS? HOW CAN I CORRECT IT. THIS IS MY ONLY GRIPE WITH THE TOW-PAC KIT. THANKS FOR YOUR HELP. RAY
