Hello everyone I need a little advice. My 2002 VTX 1800 hasn't had any updates and it has 78,000 miles, bot too bad I guess. Anyway when I picked her up she had been road hard and put up wet. The previous owner laid it down a few times he dropped it a few times and just really beat it up. Caved in the entire left side of the tank I mean just abused it. Well I fixed her up and got her back in shape fix the tank and so on. She ran like a scalded dog. Soon after I started having that surging problem so I replaced the fpr. It helped a little but still breaks up at all ranges and continues to surge. I found the ground fix and meticulously went through every connection put Pookie on everything and successfully completed it. It helped significantly but still it's breaking up as well as surging and the only thing I haven't done to her is replace the plugs. I don't think that's the problem she still breaks up a little bit here and there and continues to surge. Any suggestions are greatly appreciated. One thought that comes to mind is a bad fpr? Im sure anything is possible but is that a common occurance? Getting a bad replacement fpr any idea? Thank you all in advance for any help. Stay safe.
