Hi all, new to the forum, having serious issues with my sporty.

Little back story, picked up a 2002 883r, and it ran reasonably well. I replaced the air cleaner and it didn't seem to change much. Took the carb off to check things out and upon putting it back together it wouldn't start. Took it into the dealer, they cleaned out the carb, and the fuel system, ran fine after that, with just a couple carb farts.

I was recently on a ride and the bike started farting out of the carb after the outside temperature dropped dramatically, about 25 degrees. Now the bike won't start, it will occasionally idle for 20 seconds, then drop off. If i give it any throttle during the idle it will die.

Do I have a jetting issue? If so should I start with the pilot jet?

Thanks for the help!

 

I'd leave the jets alone at this point, problems that start all of a sudden like this aren't typically a jet issue. The first place to start is checking the vacuum line that runs from the carb to the back of your petcock. Make sure it not cracked or rotted, same for any other Vacuum lines like the one to the VOES.

Next you'll want to check for intake manifold leaks.
