I have a 1989 Raider that I just got back to running. Everything is running well except when you 1st start it up. The idle runs around 2000rpm and once warmed up it runs around 700rpm. After 1st starting it up (no problem starting it at all) if you put it in gear and give it gas, it acts as if it is flooding out. Once you do get it running, it will bog down going up a hill to the point of almost not pulling itself up the hill. On a flat stretch of road it will backfire and bog down when trying to accelerate. Once warmed up and running for about 30 minutes, it runs perfectly. No problems with pulling or accelerating.
