I am 80% through my restoration of my 1984 RM500 - the engine is done - suspension is 100% rebuilt - bearing etc. All new plastic - forks professionally rebuilt. I need help with my carb and airbox. I will be removing the airbox completely and using a K&N or Uni - both available. Is there anyone out there that has any idea how I should rejet? I will be using the stock pipe at 100ft altitude. Also need to know of any fixes or upgrades that wre popular for this bike. Thank you all for your help and I am available if anyone needs anything ever!
