Welcome to the forum. I bought one last year in Minn and rode it home to Idaho. You should be able to find a nice late model one for around $9K. Mild mods IMHO would be something like Ramaire filter, TORs pipes and a remap. This forum has lots to offer help-wise. Have you browsed the classified for one? Also, there is a facebook page for Triumph rocket owners. Do you mind traveling to get it, or does it need to be local?
Yep, intake, exhaust and tune is what I was hoping to find. I have a bike, it's just not reliable for road trips. 320HP on a bike is a blast for short trips though.
