Had the tupperware off recently for a clutch change. Replaced the exhaust studs, nuts and copper washers too. Checking for gas leaks after tightening up I measured the header pipes using an IR thermometer. Interestingly found #1 about 100℃ hotter than the rest at idle speeds. Approx. 240 ℃ the other 3 around 150 ℃ Usually equate EGT with mixture and thought #1 might be too lean (ie hot) Plug colour was similar across all 4. Readings taken at idle speed and not mid range as per normal road speed RPM's.
Anyone else out there ever bothered to check this temp. ?
Just curious :)

When i changed my exhaust to a Remus I noticed on the the stock exhaust that all the ports had different measurements due to the welds being very thick. If I ever put the stocker on i am going to clean up all the welds. If your exhaust is like mine it could contribute to a cyclinder running a little hotter from the restriction.
