Hey. Had some time today so I cleaned the carb on my recently acquired super fever 2. When I bought it the airbox was screwed into the case like it should, but as a result was not attached to the carb. Well between the reed intake and the carb there is supposed to be a piece marked "insulator" in the repair manual. I think the thickness of that missing is what's preventing the airbox from going on right.
Also derestricted the CDI. Another part to search out! There's a kymco dealer in town so may have to go there. Couldn't find it on ebay, etc.

Racing Planet is a good supplier of ZX parts. They are across the big pond so shipping can take a month or more, but sometimes less.
I may have the insulator you need, somewhere. I used 2 of them when I was running the stock intake and carb to solve the same problem you speak of. I think the intake pipe shrinks and no longer reaches. I will look around tomorrow.

Racing planet has this. 22 bucks plus a long wait. Kymco 1621A-GAM-9110 INSULATOR ASSY CARB Go on ebay and look for this part # Honda 16211-GAM-000 INSULATOR, CARBURETOR  Kymco ZX50 and Honda Elite 50 shared a lot of the same parts. This is one of them. |

I like RacingPlanet but really expensive gor me in Canada.
Parts only ever took 1-2 weeks to get to me tops.

Any chance of DIYing your own gasket? Perhaps from a local auto parts shop?

I finally found them. I will get them out to you tomorrow if you want them. The O rings are hard so some sealer may be needed to seal them up. Take note if using both spacers longer 8mm bolts will be needed, be certain the bolt on the back side is not too long. It will hit the carb and cut a hole in the passageway that is nearby. I found that out the hard way.  |

Keep in mind that this part is not symmetrical. If you install it backwards you will restrict the the flow a tiny little bit.

I found that out the hard way. Wow! Yes I'll gladly take them. Thanks for the note their asymmetry. I wonder what potential negative effects the lack of the insulator could have had? I figure the temp of the carburetor likely was higher with it missing. |

I figure the temp of the carburetor likely was higher with it missing. The goal of the isolator is in its name. You are going to have heat(engine/cvt), that's going to travel up the intake. This spacer helps keep the heat from the carburetor. If the carb get real hot, there a chance of vapor lock and it will be hard to start when hot. Plus the cooler the carb/fuel, the better its going to run. Most carbureted cars had spacers between the intake for the same reason. On other scooter intake configuration they use a rubber spacer. Gy6 scooters put this spacer between the cylinder and the intake. |

I also need to get an air filter. That is an easy part to find so I hadn’t mentioned it. The one in it has some of its foam missing...
Only two of the screws holding in the air box halves were installed. Does that matter at all? Should I throw more screws in there once I get an intact foam filter?

Id find/get a piece of filter foam and cut your own. It wouldn't hurt to add more screws to the air box cover. |

I just dropped your insulators at the post office.

The insulators came on Thursday! Thanks. If it weren’t negative degrees in my garage I would try them on right away... I think the derestricted variator will arrive today.
One thing I was considering is installing a switch on the CDI. Has anyone done that? Since it’s derestricted by bridging those two wires it would be simple to put a switch there and have the option to turn it on and off. Seems like a funny idea to have a kind of “turbo” switch. Has anyone done that? Would that cause any issues if used while running?
