Bogging out at 5000rpm

[Jvillari7]

Hi guys,

Im new to the forum, but in the summer my bike started acting up. I have a 1983 GS450 when I was riding once I got to second gear around 5k rpm the bike would start bogging out, and eventually turn off. I had my carbs clean, and don't where to start my diagnosis. As of right now I want to get my bike working for the spring time.

Best,
James

Is the bike stock of modified, and if modified detail out how. For example, if you have pods or a loud exhaust the carb jetting needs will have changed. Also, what maintenance have you done? Valve adjustment? Clean air filter? Stuff like that.

Check to see if your getting fuel flow. If it was running ok before, something may have clogged up the petcock, the vacuum line may have come off the petcock or the vacuum port or it may be clogged.
