Re-installing carburetor to airbox
Hi all. I have been using this forum for a while but never made an account till now. I have a bit of a problem so I am seeking help. I have a 2007 250r that needs the carburetor put back on.
I have spent hours looking for videos or forums for re-installing the carburetor, but have not been able to find any help. It took a while to get the carburetor off as I don't think it has ever been removed. When I went to put it back on, I noticed that the carburetor does not slide onto the boots for the airbox. I tried putting it into the boot and tried putting the boot on the carburetor as well. The spring doesn't seem to help anything and it seems the carburetor just sits up against the boot. I need some guidance on how to get the carburetor to go back onto the air box side. I was able to get it attached to the engine much easier. Thanks |

I had the same problem, and never really fixed it until I separated the battery box from the air box, and made my air box brackets. Now it goes together and stays together easily. You can find various air box separation instructions around. I was able to unbolt the electrics on the right and the coolant reservoir on the left, and use a hacksaw blade with a handle to carefully saw the two apart. My thread about the brackets shows what I did to ensure the airbox stays firmly against the carbs:

Also, the rubber runners from the carbs to the airbox get old and stiff, and seem to shrink a little. I have used pliers to "bend" the edges that go over the carb out to get them started back onto the carb. I'm sure the right way is to get new runners that are pliable and cure the problem for some years. Also make sure to push the spring back before trying to slip the runners on, they don't do much but will make it tough (impossible?) to slide the rubber on.
ps: welcome to the board

If you haven't watched his video maybe worth a look. Reverse to install obviously.

I had the same problem. I rolled the small springs back toward the airbox, loosened the screws under the battery and pushed the airbox forward as far as it will go and re tightened the two bolts. That worked for me. Don't forget to roll the small springs back over the carb intake. The next time I'm going to elongate the two bolt holes under the battery so I can push the airbox even further forward. Bill |

I got the bike back together and with all the small mods I did, it rides like a brand new bike. I put a stage 3 jet kit on it, and did a bunch of tweaking. I was about to close the garage discovered this. What does it go to? Been looking online and did a reverse image search and didn't find anything either.

I found it through a parts diagram. Its 11044 smack dab in the middle. When I get a chance to put it back on and run the bike, I'll post a video. Also, I'm on mile so the image is all messed up and I'm not sure how to remove it.

I haven't tried this on carbs before, but if you get a little bit of silicone spray-can stuff, you can rejuvinate rubber with it. Stick the stiff old rubber parts into a zippy bag, spray the silicone into the bag, covering the part(s), and then some. You want plenty in there, and it's cheap enough. Leave it for about a week and your rubber is soft and supple. If not, leave it longer.

It comes in many different flavors: but it's all pretty much the same crap. I've only used this trick on smaller rubber parts before and I'm not sure how it works on the microscopic level, but I'm assuming the silicone penetrates the rubber to some extent (or something). So, making sure the rubber intake boots are clean would probably help, and a thicker rubber like an intake boot probably takes a little longer. |

Thanks, I'll have to give it a try sometime.

Not the same part. I'd go look at mine, but it's strapped in my van with tie-downs at the moment and I won't be able to look under the seat until tomorrow. I think it may be part of the air box hold-down parts.
