never don't give up on her yet. i am not an expert nor do i claim any crazy carb skills but i got my older bikes to run and it was not impossible find some time and find the manual then figure out what you are looking at 1. idle screws 2. needle clip 3. jet size 4. carb sync try to find out what was stock adjustments then look at what was done to the bike new pipes, aftermarket air filter if you have upped the airflow you need to up the fuel rate
