Hi everyone. I need some help. I just got a 1996 Yamaha Kodiak that I traded a couple of guns for. It's a 400cc 4x4. It will crank up and idle just fine. When I give it too much throttle, both in neutral and when actually riding, it starts spitting and sputtering. It is backfiring too. If I give it full throttle really fast, while in neutral, it bogs down and tries to die. If I ease into it, it'll rev up all the way. I can drive it down the road, but have to give it easy throttle. And even then, it'll start bogging down, regaining power for a second, and then just keep repeating till it finally just wants to die. It has a brand new fuel petcock, fuel lines, and carburetor. It also had a brand new intake boot (carb-to-head boot). But the previous owner ripped it, when he installed it. I thought that was the main problem. So I just temporarily repaired it tonight, till the new one that I ordered gets delivered, but it's still having the same problem. Has anyone ran into this before, and figured out what it was yet? Could it have possibly jumped time? I appreciate any help. Thanks!!
