Hi guys, got a problem and i was wondering if anyone had any ideas. Problem started with the throttle sticking so i took off the air filter and noticed that only the left carb was sticking open ever so slightly, but only while running. The slide is not sticking at all and moves perfectly fine when not running. So with the air filter off i took it for a test ride and....problem fixed! Put the air filter back on and it would stick again. The air filter is clean so it seems to me that the problem has something to do with intake vacuum sucking the slide to the front of the carb. Any suggestions would be greatly appreciated! Thanks!
