Hey all, here’s the problem I am having. I bought my 1999 Vmax in May of last year. I bought it from an elderly gentleman. Drove two hours home from Orlando, Florida to where I live on true west coast. The bike ran perfect. It has 35,000 miles on it. It is an excellent condition other than needing just a little polishing. Molested the only mods that it has is a Kirker exhaust system. I drove the bike to work after that a few times and around the neighborhood. I always keep it on a battery tender. Started it up at least once a week when I wasn’t using it. Usually just push the choke all the way down and starts right up and then ease off the choke fairly quick and it would run fine. Last few times I went to start it after sitting for a little while it’s starting to get progressively worse and not want to run.
The bike has run perfect and all of a sudden this started happening. Trying to make a long story short, I bought brand new factory plugs (NGK) , gap them to the correct gap (0.35) I change the fuel filter so try a factory Yamaha filter. The old one looked like it had not been changed in a long time. I also changed the fuel pump with a brand new factory Yamaha fuel pump. It will idle a little bit better now with the choke on, and I can get the choke almost off with it barely running. It will not let me give it gas or it will stall. If I spray starting fluid in the carbs, I can give a throttle as I’m spraying it and it will rev all the way up and run fine as soon as I let off it, it will idle with the choke on a little bit, but I cannot give throttle or it will die. I just don’t understand how this has all of a sudden happened. I have a 2004 big dog with a 107 S&S motor on it. I am very familiar with that bike. But this bike is a whole different ball game for me with the four carbs. Any help would be greatly appreciated. Thank you all so much.
