Have a 600ss that was sat for a while and has had new belts and a carb and fuel tank clean out along with new battery and plugs etc. it’s now running, but backfiring occasionally at low rpm and seems to hang a little on the revs too The old zip tie trick shows that the rear bank is running hotter than the front too. any thoughts ?
Or blocked carb. ( you don't say it's year ) Lots of small jets easily get blocked. Also italian electrics , clean all connections. Some years the ignition systems tend to die with low use.
