So Ive had my bike for about a month now and have found it is an ongoing project. Im learning alot and have figured out alot of my problems on my own with a little help from all of the nice people on this forum. Thanks all. Any how my current problem is that I am not getting full power and its like the bike choses when it wants to run full bore. So to describe it. I will start the bike and warm it up for a minute or so. Then I will ride it light and warm it up a little more for the first few blocks of my ride. When I hammer on it sometimes it opens wide and some times it makes a lower tone sound out of the exhaust and will only go about 15mph. When it opens up randomly I can reach about 30-33. I want the throtle to be more responsive. I have played with the idle screw and have it right where it sounds healthy. the gas is 30:1 which is what the bike directions call for. I am stumped as to why it only opens up when it wants to. any suggestions? The bike is fairly new and broken in too. Thats all the info I can think of right now. Any suggestions would be much appreciated thanks
