believe me, that's possible. When I got mine, it worked fine for 2 days (albeit with a funky idle) and then stopped working completely the third day because so much crud had clogged up in the carbs.



OP, if the bike is back up and running currently, maybe taking the carbs completely off to clean them isn't 100% necessary. Try just running some SeaFoam (or other carb cleaner) through with your next tank of gas. It certainly won't hurt anything, even if it's not necessary. It's a good idea to run some carb cleaner through every few tanks anyways.

Technically, a traditional choke uses a "choke valve" which is a sliding perforated tube used to throttle the air intake (not gas) at low velocities, while butterfly valves are traditionally used to choke off the airflow at higher throttle openings. The symbol for a choke circuit is the butterfly valve, and this has been extended to use on enricher circuits, and even to idle speed adjustment on fuel injected bikes by Ducati. If any of that makes sense to you, remember that applying full throttle technically means completely restricting the intake and stalling the engine.

Here is the air box mod if you have to remove the carb:
