I've recently bought a used 2010 tank vision 250 topline khaos and, from the get go, I've had some trouble. While I am not new to motorcycles, I admit that I am not very knowledgable when it come to diagnosing certain issues. Here is a bit of background for the bike: the original owner bought the bike simply because it looked cool. He then decided to take it to a bar to show off and ended up drunk. He went to get on the bike but fell off, causing the bike to fall on its left side. He then tried to pick the bike back up and proceeded to drop it on its right side. This broke the front fairing, the front brake handle, and the left mirror. The foot shifter was bent back and the foot brake was bent as well. Know that you know about the bike her is what I've done so far and her is what is still wrong. I've straightened out both the foot break and foot shifter, I've fastened the loose front fairing and fixed, as best I could, the left mirror. Now here is what is still wrong with the bike. The idle needs to be adjusted, the foot shifter is loose and doesn't always shift, the bike will start just fine and shift into first gear just fine but, after stopping at an intersection, I try to take of and the bike will either, very slowly and with some sputtering, start going again, or just sputter and stall. I've also tried to up shift to second gear and the bike will immediately stall, no matter how smoothly I let out the clutch. I've also noticed that the spedometer doesn't work and the tachometer is very sporadic. I want to take this entire bike apart, clean it, and put it back together... Starting with the carbs. I want to get this bike back up and running but I just don't know where to start. Please help!!!
