Just recently bought a 1982 Sabre. Looking for some information about exhaust and other things. First, I've seen the 4 into 4 exhaust on the Magnas from the 80's, will they bolt up on the Sabre? Kinda new to these bikes, from what I've seen the motor is pretty much the same. Or am I retarded? Second, is anyone familiar with performance mods to this engine? I've researched and keep seeing DRP and Dave Dodge. Looking for a little bit more cam and the like. Is this possible? Bike performs decently, I'm always looking for more. Kinda like a winter project for me. Any info would be great. Thank you.
