Have a 2002 M2 with stock carb. Been coughing and back firing more than normal. Think a carb cleaning is in order. any one got a part #? do they sell a rebuild kit? Got about 25 K miles on bike thank you. |

It's probably your intake seals where they meet at the heads. With the bike running spray WD40 on them all over. If the bike speeds up or slows down that's your issue. Search in the KV or here and there's lots of info on the removal. I bet it is your intake seals. They're only good for about 2-3 years. If you don't hear a change it is your jetting/carb. Buy a $6 #45 pilot jet from your dealer and turn your airscrew to 2.5 to 3 turns out. No need to buy a whole kit. First take as much of the brass out and let it sit in carb cleaner for an hour or so. Alternate with lots of carb cleaner and compressed air each hole. Don't get carb cleaner on the top rubber diaphragm. When you spin it in don't force it, just until it slightly bottoms out. Record where you were to start from, just in case you have to put it back to get it to run. Try 2.5 out and turn slightly until you find the sweet spot. Small turns, then ride. If you need to go all the way to 3 you need a #48 jet and restart at 2.5 out. |

I would second the intake seals given 25k and perform the WD-40 spray test to rule that out. Assuming you haven't experienced the coughing due to a recent changing of the intake and exhaust I don't think you'd have to change the jet - But, if the carb has any sediment in it it could clog the small pilot jet and maybe a bleed hole or something that's creating the problem - again, if it's not an air leak at the front or rear of the intake manifold. And, if you didn't change the intake or exhaust. |

check your breather bolts, found mine finger tight, safety wired after a rebuild due to Cawater in tank. I have a force inlet. You may be able to make a french washer to retain the torque. A (french)washer has tabs is bent over the hex and the adjoining bracket. a fender washer may be suitable for this use. I do not remember the assembly as it was. |

I did the dyno-jet kit and after a few adjustments I have no problems. |

If you stick with the CV-40, I HIGHLY recommend the Thunderslide kit. Makes a world of difference. |

Aren't they called 'freedom washers' now? |
