Problems when throttling... Again

Hey everyone. I've been having problems with my 02 recently. It has left me stranded at work a few times already. Just 2 months ago, I took my bike to the shop to get a full carb cleaning and some other work done since it was not running very well.

Problem: After the carb cleaning, the bike was running ok for about a month. Then, it started having issues throttling. I was riding to work and it seemed like the engine was choking in the front cylinder. Shortly after, it would just choke and die when adding any throttle.

I was able to get it to throttle only if I closed off the air intake my 75%. I put some seafoam in the tank and ran it with the partial intake closure and it seemed to have blown whatever was blocking out. It then ran ok for a bit, but 2 weeks later, same issue... But this time, the seafoam only worked for a day.

What could be my issue now?

Use the forum search for problems with,"Choke Plungers".These can become corroded and stick.

Also check the drain hole in the front cylinder spark plug well. I can get gunked up and not drain after some time, allowing water/debris to build up in the spark plug well and short out the front cylinder. I had that happen to me once after getting hit with a heavy down pour.

Re: Problems when throttling... Again

If checking your spark and carb choke system don't work, you may want to see that there are no debris or rust particles in the tank. You could try adding a clear inline fuel filter to help you see if anything is getting past the petcock and straight into your carbs.
