Lake George NSW
i made this in an attempt to reduce a large spread of EGT’s, #1 was lean and #4 way too rich.
it is made from 3 inches of 2 1/4″ 6061 and two smaller diameter tubes i cut from an old windsurfer boom.
i inserted it in the SCAT between the airfilter and the carb, about 1 1/2 inches from the carb.
the EGT’s are now a lot better.
