Tune-Up-Date

After installing the new heads, and getting the tune up on the dyno.
The tune up was a huge waiste of money. The jets were put back to what I had originaly, The powervalve was replaced to what I put in the first time.
Once this was done a friend form the car club had an aniliser that measured the air fuel ratio. An ajustment to the vacum secondary spring to make the secondaries come in later.
After a test drive yiu could feel the defference straight away. The sound of the engine was gruntier as well.

This was really good as the Marsh Rodders drag Day was fast approaching....
