I'm having a small hiccup in the midrange and was thinking it could be a possible air leak in my old carb boots. I had visually inspected the old ones before I fired it up for the first time and although they were cracked on the outside the insides still looked solid. To try to remedy the hiccup I thought I'd start with the obvious possibilities first. I bought new carb boots because I knew it would be something I needed to do in the near future anyways. While I was in the carbs again I noticed some small debris around the jets. Most likely just dust from the air filters from sitting so long. I cleaned them up and threw everything back together with the new carb boots. The good news is there was noticeable improvement. The bad news is the hiccup is still there, just smaller. Could this be due to the old filters just not providing enough flow? Are the tiny jets that aren't removable the cause of this? Since I can't remove them I haven't been able to give them a really good cleaning.. The bike runs really strong in the low range all the way to the midrange, it hiccups at the midrange, then continues on to the high range. I've noticed if I roll off the throttle a little and hold it steady the bike will run itself through the hiccup and I can get back on it. If anyone has had any advise on some possible fixes I'd appreciate it!
