I own a 00 M2 this winter I did not put anything in the gas tank to prevent the gas from changing.So when I started the bike up last week It sounded like it was only running on one cylinder.I tried to run The old gas out of the system but it has gummed up.I am a auto tech but of the new generation,meaning I dont know much about carb systems other than general operation. I am thinking of removing the carb and cleaning it out. If anyone has done this before please let me know how difficult it is to remove the carb.From looking at it does not seem to be a problem.But I would like some advise being this is my first time removing a carb from a buell. | ||

It is easy. VERY EASY, A little too easy  But seriously, be very careful of the diaphram on the top of the carb (under that big black plastic circle) if you get gas on it it will expand, also if you rip it you are looking at $50 to replace it. Just take your time and it will be fun. P.S. Check your plugs first that is useally why mine runs like crap. | ||

I think you just fouled a plug. There's nothing about the carb and intake that would cause one cylinder to not get air/fuel. If you're set on taking your carb apart, I would tape the frame rails around the carb area. You can scuff the paint pretty easily wiggling the carb around. Not an issue if your still using the Helmholz - you'd never see it anyway. Like Spidey says, it's pretty simple. And thank goodness, there's only one. I'll never spend another weekend over a bank of four Mikunis again... | ||

bigbx1, Might want to try spraying carb cleaner or contact cleaner into the air jets in the belmouth of the carb before completely removing the carb (you just have to remove the airbox to gain access to the carb throat). Sometimes you will get lucky and thats enough to clean the slow jet. The air jet on the bottom left with the larger diameter orifice is the slow circuit, the one on the right with the smaller orifice is the main circuit jet. If that fails, might be worth pulling the the carb. Couple things to watch pulling the carb: fuel fitting on 2001 and down carbs has a platic fuel inlet that can break if your abusive to it (newer ones have a brass fitting). Make sure to unbolt the choke cable from the bracket before pulling the carb, and watch the VOES vacuum line when re-installing making sure it didn't pop off. Good luck! | ||

Bigbx1, Consider the possibility of a bad intake gasket at the head. When they first fail it usually drops a cylinder when cold and may clear up as the cylinder comes to temp. It's an easy fix and is pretty common for the rubber in the seal to go bad after a couple of years. SteveH | ||

Hey Bigbx1, Did you fix the problem? I just fired up my S-3 after the winter sit and had the same thing happen to me. I'm interested to see if you solved the problem. |
