I am all stock with a UNI filter and removed spark arrestor. I tore the Carb down and cleaned it built a solid 2 in PVC snorkle from the air box to the headlight height up front ill post pic when I figure it out. Also drilled the bottom of the lid where its solid, still sealed on top. I wound up with a cap for the end of the snorkle with a hole very close to the size of the stock intake tube size. Wide open is to much for stock jets. I did open the fuel screw about an 8th turn from factory. I did clip 4 coils off the Carb spring but did not drill the slide but will when I have it back out. She runs stronger then ever and the mixture feels and sounds perfect I would do it all over again!!

 

Today I found BIG GUN slip on for a vinson. It has been welded on so ill have to fix it up. Wondering if anyone has one and it specs I've read that it runs well with stock jets? I would like to be able to use my snorkel to full potential and open it up. Any info is appriciated if needed who should sell me jets
