Tuning with the Bergen Muffler

Postby cbergen » Mon Jan 15, 2007 11:39 pm

With the Bergen Muffler designed to run on the G26 engines installed, some slight needle changes may be necesary.

So far, we have found it necessary to richen the needles, both low and high about a blade width from where the engine was tuned previously.

Start with this and work your way from there, paying attention to high frequency vibes that may indicate the engine is still on the lean side.
