I have an 08 Heritage, I'm wanting to do some motor work without spending a ton of money to give me some more takeoff, now I have a screaming eagle race tuner and slip on rush pipes with the air filter changed, this was all completed at HD dealership before I picked the bike up. I now have 3800 miles on it. Would just like some more hp on take off. Tks

 

Best bang for the buck would be nitrous, but the smartest thing would probably be to just pulley down.

Most bang for the buck in my case was new Andrews cams. Tons of low end torque.
