But it’s not a bad result for my 18 yr old Thunderbird; when new the standard bike made 67bhp. The guy in the dyno shop did say that the silencers are the main restriction, he reckons he saw another 10bhp when he pulled the baffles, but as they’re already loud as hell that’s not an option. Maybe I’ll look around for some better ones.

Ah, the trials and tribulations of running an older bike.
