I have a 1998 zxi 1100. It has always been hard to start but once I get it started it runs all day with no problems. I solved the problem by installing a kit that lets me manually pump gas into the carbs before starting it. It seems like I have to pump a lot of gas into the carbs when the engine is cold before it starts. I've heard of others with the same problem who solved it with this kit. Is this common to zxi 1100's, or is there something else I should have done; e.g. rebuilt the carbs?
