Hi all I've got a 2013 Yamaha Cygnus X, bog standard, with 12500 miles on the clock. It's in great condition overall, and I'm very happy with it reliability wise. I've recently changed the air filter (old one was filthy) and spark plug (looked fine but probably hadn't been changed since new), and it's running really nicely. I'd really like to give it a bit more oomph off the line though. I don't want to modify the engine and am not looking for huge performance gains. Don't mind losing some top speed as I never ride it anywhere I can get it over 50 anyway, but some fiercer acceleration would be great! What do you guys recommend - variator? Rollers? Anyone else have a Cygnus X here? Any advice on any other worthwhile mods? TIA.
