Ok thanks can you tell me what numbers are on them , it's guy who does my suspension asking me for them the 95s too stiff he'll be doing both ends as even though it's an older bike im going to race it , it's a 390 so I think they are slightly longer , I was going to ask you if you knew of an exhaust available for it or something like a vortex ignition , I raced one in 2011 and 12 with an akro and different map but nothing seems to be available for them anymore
