| Post subject: | exhaust design question |
Since I put the H1 engine on the suzuki frame I had to modify all 3 aftermarket pipes. I had my local welding shop do this. The outer pipes had a tiny wedge cut right after the front curve. Then were rewelded so the over all curve was brought up an inch or 2 depending on the pipe. But my middle pipe was cut to have the angle raised and rotated a little. All my cylinders have the same compression. But the outer pipes have a nice pressure pop to them at idle, and the center pipe doesn't. I am assuming I lost some design quality to the center pipe by modding it. Any ideas how I could fix this problem when i tear it all down this winter? I have tried jetting, packing and all that. I am pretty sure it is from my mod. Maybe a ridge from the weld on the inside? |

Your center pipe feeling different at idle is not caused by small changes made to your expansion chambers. Clogged pilot circuit, or bad sync, etc., are more likely causes. |

I have re synced them many times. Clogged pilot circuit...hmm I will have to give that a try.. It does seem to make a difference when I turn the air screw though. |

Good call Jim, I switched the center and right carbs around and the problem followed the carburetor. |
