Re: engine problem
If you keep having problems after the good advice above, check your fuel line. I had a similar problem when I first finished my bike. I would get fuel flow, and it would start and run ok with no load, but under load, it would starve out and die. It was clearly starving. I put on a clear fuel filter below the tank. You could see it run dry. I took off the tank and shut-off cock, and rinsed and blew them out, and also disconnected at the carb and made sure there were no air pockets. I didn't 'see' anything in cleaning, but theory is there was some piece of metal filing or such. All fine now. And make sure the gas cap is venting. There is no fuel pump, it just has to trickle down, and does not take much to shut off or slow down flow.
