FCR-MX 39mm oring mod without removal?

Recommended Posts

Hey guys, I have a fcr-mx from the previous owner that bogs on quick throttle opening. I think it needs the oring or wire mod done to solve this as jetting hasnt changed the issue. I dont have the time to take the carb off the bike right now as its also my daily driver and because it seems like a huge pain. I notice the stupid black cover still on the carb like in the picture I posted. Does anyone know if its just one screw on the front face(near the top) of the black cover to remove it? If so I think I should be able to take it off with just removing the gas tank and then from there I should be able to carefully slip an oring on or wire. I know its tight but someone mentioned on a popular FCR forum that it could be done with it still on the bike. Anyone else done the mod with the carb still installed?

yep that one screw and you can do it while its still on the bike

Perfect, Thank you. 

That was the forum I was talking about. I just didnt know if they meant you could do it, even when that cover was still on there. Every tutorial has the carb off the bike, I have never seen anyone do it with it still on. This will make things a lot easier for me.
