I have been messing around with getting my engine running right for a few weeks now. It really seems like I have a fuel problem and I just need to play with the carb but Im asking just incase its something else. First the bike was really lean so I got a different stock carb that I can adjust and the guy says it had a #60 jet in it. Im going to change that back to #58. The bike starts fine first kick. I adjusted the idle down and let it warm up to take it for a ride to see how it runs. It warmed up just fine but when riding it really seemed to sputter and almost surge then died out after about 5 mins of riding and now wont start. Im thinking its to rich now and its flooded but I was looking for any other ideas. The spark plug is black btw and the o ring going from the intake manifold to the carb is pretty bad so I need to replace that too. Any advice would be great. Thanks.
