Re: Adding compression
Building a 600 = baaadd idea....you'll need boost, and that's not a fun road to go down, trust me. You really have no idea what you're headed for.(it starts with holed pistons, and ends with picking the rest out of your oil pan)
Then after all the money you dumped into it, you realized you could have just bought a FZ1 or whatever the fuck.
Just buy a second or third bike, like a sane person!
