I have a 2006 ktm 400 exc, street legal. I plan on riding from ohio to the Grand Canyon . Is it gonna make it, will it break down a thousand times? Also I'm having a problem with backfire on deceleration, I have cleaned the carb replaced the silencer and done minor throttle adjustment. Other than that runs super strong will do 95 no problem cruises smooth at 70. Any help or input appreciated.
