okay, the bike turns on and i have the choke fully opened and when i open the throttle it turns off on me. What i noticed is that on one of the carbs there's a sound like "poof". I put starter fluid and that's the only time that it starts and then after like 10 to 20 secs it turns off. Can somebody help me out.

Check for sticking float valve needle or incorrectly set float level. Float level too high = rich fuel air mix and float level too low = lean mixture.

Sticking float valve needle is a common problem.

I should add that it is probably best to avoid using starter fluid as it washes the cylinder walls of lubrication.
