Got a 1975 Honda CL360 not to long ago and the PO had cut the pipes so that there are no longer any mufflers. I was thinking of buying some slip-on mufflers to remedy this issue, but my major concern is do the carbs need to be rejetted given that the pipes have been cut. Or, since mufflers are being re-added to the system it will reach somewhat of an equilibrium saving me the trouble. As a side note stock air filters are being run on the system and my current jet is size 110 so it should already be running slightly rich.
