Try this on for size. i get blowback through the horizontall cylinder carburettor, when bike has warmed up. changed the coils, reguiator,battery and spark plugs. |

:confused: This sounds a bit strange, minimad. If you're having trouble on just one cylinder, why change the regulator and battery? If the trouble is spark, how come it only happens when the motor's warm? How about checking out the front carburetor? Does it blow back under acceleration, or at idle? Maybe the front carb is rich, so it runs OK only when cold. |

How well are your carbs synchronized, are you using reccomended plugs, and does the front plug look rich or lean? |

yes and yes. it's carbon fouling both spark plugs, with both bigger jets and small jets. it's like the motor start to run on one cylinder, and starts to fire at uneven times. can't reuse spark plugs again, even after cleanup. (motor won't start) |

So you're having trouble with both cylinders? |
