Im in MN for the next week or so riding (here for weddings). What are you running for screws here? My lower pipe screw is about 1 and 1/8 out. Top pipe varys between 1 and 2. Carb screws are still bone stock as far as turns. I'd be curious to see what you run here and set up my 50 cal like that for the next week and see how much I can get out of it... THanks!
