Lean cylinders?

[mattmcuomo@yahoo.com]

Anyone else have the two inside cylinders look like they're running too lean? Am I being paranoid?

I think that it is just the nature of an inline, air-cooled, four cylinder for the inner cylinders to run hotter. They are not getting the same air flow and they have less fin exposure to the air.

My inner two header pipes also tend to blue a bit more than the outer two (especially at the top edge near the flange). Some OptiGlanz and some Autosol metal polish usually takes care of the discolouring for a few months.

I figured that the two inside run hotter, I'm being paranoid. I don't mind the look really.
Thanks

How do the #2 and #3 plugs look? If they're about the same as #1 and #4, I wouldn't be too concerned.

Good question, I haven't looked

Every aircooled inline 4 i've ever had runs hot on #2. Nature of the beast.

Boy do I wish my headers looked like that.

How can I make my outside ones look as cool as the inner two?

Propane torch, lots of care, and some learning as you go.
