Starting to look for a credible shop in the Seattle area or as far as Oregon to get a port job done. I currently have the time advanced 5 degrees, 35mm carbs open pod filters, 21mm domes and Pro- Circut exhaust. Took off boost tube and put on billet intake with built in cross over. Other than that, stock motor running premium pump gas, not quite wanting to go trick ot alcohol, yet... My style of riding is sand, hill climbs, and drag racing with buddies nothing like pro. Heard of a dune port before not sure if that is even a port. Any advice would help, thanks.
