Dented #3 & #2, 4-1 pipes

[xj11john]

I'm thinking the reason why I have one plug and carb that acts alittle funny is because the Pipe coming off #3 cyl. is pretty dented, not much room for exhaust to go by.

with that said anyone ever had similar experience, and what did you do to get the dent out of your header pipe(s). ??

crushed

i've had a header pipe almost crushed flat and the plugs still looked fine on mine.You must be XSperieancing carb issues.

.. yeah, the bottom two pipes on my 4 into 1 on the "Ugly" bike are flattened some also ..i thought this would be a problem but the plugs all have the same color and the bike runs pretty good
.. unless yours are pinched all the way flat this might not be your problem

I guess it is a carb issue since it doesnt seem to affect you alls plug color, thanks for the input.
