Hey guys, I just picked up an '89 Ninja 750, and had a couple of questions. The place I got it from said they did a full tune up on it back in November, which included going through the carb, and replacing the jets. He said they went with factory specs on it. It has a Muzzy exhaust, and the guy said they put the K&N kit on it, in place of the stock air box. It's got just under 20k on it. I'm getting a dead spot around 4-5k, but below, and over that it's just fine. I can run right through that accelleration and never notice it, but if you hang too long there at cruising, it falls flat until it breaks through 5k. They told me the carb just needs to be readjusted because they didn't take into consideration the exhaust and intake, so it's running lean in the rpm range. My question is, does that sounds correct, and if so, how do I go about making the proper adjustments?
This is my first bike, so I'm still learning the mechanical side of it. I've read a lot on here, and it seems that might be a little big for a beginner, but I'm extremely cautious when it comes to riding, and other people on the road. And yes, I'm already signed up for a course.
