I own a 2005 MV Agusta F4 1000$ with 20,000 miles. I've put 6000 of those miles on the bike. I've been diligent with the maintenance and have taken it to the dealer for basically everything. I had the major 15,000 mile service a few months after I bought it. I haven't done any crazy modifications. I've added the Muzzy fans and that's about it. Recently, the dealer replaced a fuel injector relay.
Anyway, my bike starts up no problem. It's when I start to ride that things get nightmarish. Idling at a light, she sounds like an old VW Bug that is about to cut out at any minute. Some times she dies, sometimes she doesn't. One thing for sure is that I have to feather the clutch and rev the engine to get her going. When I'm on the highway, if I open the throttle nothing happens for about 5 seconds and then I'll be hit with a surge. It doesn't matter what gear I'm in. Even with a steady throttle, the bike will surge. It feels as though it's getting a lot of fuel and then not enough. With this problem, turns become things to be avoided because I'm afraid a surge will kick in while I have her leaned over. I've tried fuel additives, changing gas stations, all to no avail. I live in a pretty humid and hot area. Lately, it's been 89 degree but with the humidity it feels like 95 degree. I really hope you guys can shed some light on the situation. I'm very frustrated and don't know if I can take it any more. I haven't had one trouble free ride yet. It's a pity, because she so beautiful to look at, but not to ride. Any ideas?
