[Aldrich]

hey need some help tunnin my 720 motor... I ride 4-8k feet, Right now it has 330/320 jets, Pilot size is 40 and air fuel is 2 turns out.

Thing wont start, when it does it bogs out.. Plugs are wet when i pull them, but to keep it to idle i have to prime it.


any ideas on what Jetting size, Pilot size and air/fuel turns thanks....

edit, running with single pipe

I'm not sure but my 99 670 with altitude compensator came stock with 350 mains. The dealer pre-delivery set it up with 320's for 10,000'. I am a surprised you are running rich.
