Old Truck Junkie
I rejetted my carbs with a jetting kit from no one other then Lance. I let him know my altitude and the exhaust and no ears. Anyways after the installation I was having a problem with not reaching high rpms. At Lances advise I tried removing the EMGO filters. And still no change. I went throught the process of changing the jets and shims around, still a problem. However; when I removed the filters I did not remove the entire filter. I had left the rubber part on the carb inlet. This rubber part was causeing the problem. It partially covers the air ports at the mouth of the carbs. So what we did is go with what lance sent me and removed the entire air filter and wala, high rpms reached. I am waiting on my new K & N air filters. The moral of the story EMGO filters not good for this application.
