80" Evo cams
Need a little advice...i picked up a 2008 SuckerPunch Sally bobber...bike came with a 80" Evo motor. My other bike is a 2007 Road King with a Rev Perf 107", Woods 777 cams, Barnett clutch, SE pushrods, Thundermax etc. I would like to hotrod this bobber out as well. I'm just not as familiar since this is my first Evo I owned.
I'll do alot of bar hopping on this bike but i recently just did a few 200+ mile days as well. Any recommendations on cams for the 80" Evo. I did a search but a lot of the talk was for bigger bikes. keep in mind, this bike is small and light as hell. thanks.

A lot of the smaller distro bikes may have "punched" out engines already. A lot of guys in this forum, best on earth, hate to admit how much faster a Twinkie is than an Evo.
I would sincerely doubt you have a moco crate engine in yer frame. You could call SPS and maybe Ami will answer if he ain't too busy tattooing somebody's ***.
