Xj650 going back to airbox from pods

Hi guys,

Had a bit of a search with not much luck.
My bike is currently running pod filters (how I bought the bike) but for registration issues i need to change it back to the original airbox. I've found a second hand airbox that's in good condition, however will I need to retune the bike and possibly re jet the bike if it's been running pod filters? If someone could point me in the right direction that would be great

 

If the carbs have been jetted differently than stock for the pod filters, yes. Unfortunately there is no way to know until you remove the carbs and open them up. Which you will need to remove to install the airbox anyway...

 

To get the airbox in you will have to take the carbs out so... definitely not an issue checking the jets but don't forget getting the airbox in is going to be exciting without engine relocation... don't be too shy to use a heatgun to give the airbox a bit of flex when you are jamming it back in otherwise.
Good luck! and I think, even if just for wet weather, putting the airbox back in is a great idea.

 

You also need to ensure the diaphragm springs have not been shortened (or exchanged for something softer) and the diaphragm hole in the vacuum piston enlarged.

 

I actually didn't have much trouble at all installing an airbox in the 81 650 maxim. Pulled the carbs, carb to head boots, seat, sidecovers, and the starter. With some careful wiggling and looking at the other maxim to see just where it needed to be it went it without much trouble at all

 

I cracked the airbox part putting mine back in but I plastic welded it back together using a soldering iron and a few cable ties as the filler.
Worked a charm and the bike works like a charm now... even when it is raining.
