I just got the bike after it has been sitting for a while. When we first got the bike it didn't run at all. I emptied the gas tank, soaked the carbs in carb cleaner, and idled a full tank of new, clean gas through the carbs and the bike idles like a champ, but takes nearly 20 minutes to get to the point where you can actually rev the bike past half throttle without it stalling. For a while the bike ran great, was able to rev to full throttle with no problem. Well the other day I went to go take it for the first ride and it revved great, and as soon as I went to go ride it, it won't rev past half throttle. No matter what, riding downhill, uphill, flat or even just sitting in neutral, the bike doesn't want to rev past where it would for half throttle no matter the throttle position. Is this a problem with the secondaries, if there are any? Also, is it normal for the bike to take that long before it's even remotely rideable? Thanks everyone!
