Hi guys This issue is driving me nuts! What happens is the bike starts to hesitate and bog down after roughly 5 seconds or more of full throttle. Ill then have to back off the throttle and itll be ok while just cruising, but if i then stop then engine will stall for sure, and it wont start back up straight away unless I apply full choke. Even if i back the throttle off before it starts hesitating it will almost always stall as i pull up the to the lights etc which is annoying and embarrasing as i cant start it back up straight away. If i apply full choke it will start immediately, so obviously its a fuel problem. Could someone tell me where the mixture screw is on the carb on this bike? Presumably its a mixture issue? Btw unless i go full throttle for more than a few seconds, the bike runs fine and never misses a beat. The problem occurs whether hot or cold! And it's a 2007 model. Plz help! I know a fair but about cars but mainly fuel injected, and im fairly nift with a spanner so if someone could just explain to me what they think is going on with the fuel i should be able to tune it up. Is it gradually flooding? Or running leann? Maybe the carb cannot get enough fuel and is being starved? But then why would it start on throttle close?
